Posted by Keats Manufacturing on | Comments Off on Vehicle / Car Electrical System
Modern cars have a range of electrical connectors and terminals that control the internal system. This complex equipment controls and operates dozens of functions while providing critical real-time information to the driver. As the world makes the transition from ICE (Internal Combustion Engine) to electric-powered vehicles, the technology and components needed to support that transition will change as well. The main components of an ICE vehicle’s electrical system are the starter, battery, and alternator. The battery is a source of energy for the starter, while the alternator provides power to the car.With electric vehicles, there is no longer a need for a starter or alternator. The main battery provides enough power for the propulsion of the vehicle as well as the operation of all of the other components within the vehicle.
How Does Your Car’s Electrical System Work?
The primary function of a car’s electrical system is to generate and store energy while supplying electrical current to power the various car systems, including power windows, digital devices, electrical gauges, a central locking mechanism, and more. This system offers precision control and convenience of operations.
The electrical system is incorporated throughout the vehicle to ensure communication between all parts of the car with the help of a central computer. Power is distributed from the main battery through a PDU (Power Distribution Unit) to all of the other components within the vehicle.
Most electric car batteries operate between 300-800 volts which is substantially different from the traditional 12 volts from ICE vehicles. This system has very different requirements for components. Since the battery provides the power needed to propel the vehicle as well as operate all of the different functions and controls these cars have circuits with high amperage and bigger parts to efficiently bear the load without failure.
Vehicle Electrical System Precision Metal Stamped Parts
How does Keats play a role in the automotive electrical system? We produce precision metal stampings, wire forms and assemblies. We specialize in copper alloy parts which can be found in nearly every component within the vehicle electrical system. Some examples of the components which Keats supplies parts for are ECU (Electronic Control Unit), Power Steering Sensor, Internal and External lighting systems, Adaptive Suspension Sensor, Ignition Coil, Fuse Box and many more
Some of the main components of a car’s electrical system include the following:
Terminals
A terminal is a conductor attached to the end of a wire within the vehicle that easily connects the various electrical parts within your car. Nearly all of the terminals within a vehicle are produced using the progressive stamping process. Once produced they are crimped to the ends of wires and become part of a larger wire harness. These terminals are responsible for electrical conductivity by providing power to the vehicle’s systems along with mechanical and electrical resistance to withstand harmful elements. Therefore, the durability and high quality of the car terminal connectors are crucial.
Bus Bars
Bus bars are an amazing engineering feat that helps make complicated systems of power distribution simple, flexible, and more affordable. The battery bus bar is typically located inside the panel boards, busways, or switchgear and conducts an electrical current. This component enables the new electrical circuits to branch off at any place along the busway route, rather than branching off the primary supply at a single location. The car battery terminal bus bar connects high-voltage equipment with low-voltage devices within battery banks and high-voltage devices with electrical switchyards. There are also busbars located within the fuse box which play a key role in distributing electricity throughout the vehicle. Busbars are almost always made from copper. Keats specializes in the production of automotive bus bars using progressive die stamping and stage tooling in order to ensure the most stable and cost-effective production of these critical components.
Wire Harnesses
Wire harnesses are bundled wires and data circuits, but they are so much more than that. Think of a wire harness as the nervous system of the vehicle. Every switch, light bulb, sensor, assembly, regulator, gauge, or button needs to receive power from the wire harness and oftentimes provide a signal back to another component. As vehicles become more and more complex through the use of sensors, the need for more complex wire harnesses with more connection points becomes larger. At Keats, we specialize in developing the terminals that attach to the end of each and every wire in the harness and work directly with our customers to develop custom stamped terminals and connectors to meet the changing needs of the electric vehicle market.
Switches
The EV switches within the car’s electrical system shut off or switch the power supply off from a battery circuit system. These switches protect the car as well as those around it from accidental electrical shock. The most common or easily recognizable example of an automotive switch is the one used to raise and lower the windows. Switches provide high-performance safety due to their interlocking design, which prevents a false power supply. Keats supplies critical components that are used within these switches such as spring terminals.

Posted by Keats Manufacturing on | Comments Off on Key Considerations When Choosing a Metal Stamping Partner
Metal stamping is a manufacturing process that employs a specialized press, as well as tool and die set, to form sheet metal into a specified shape and size. Industry professionals employ metal stamping processes to produce a wide range of industrial parts and products. When looking for a metal stamping partner, there are several considerations to bear in mind. You’ll want to vet a company that offers the greatest value for your project.
The following piece provides an overview of some of the key factors to consider when choosing a metal stamping partner. In addition to metal stamping capabilities, qualities such as a broad selection of other fabrication and finishing services, extensive industry experience, and high quality standards are indicative of a high-value partner.
Partner vs. Supplier
When sourcing a metal stamping company, it is important to know the difference between a supplier and a partner. While a supplier has the metal stamping capabilities necessary to fulfill the project, a partner offers the required metal stamping services and more. The latter should be able to assist with all project needs, including design and engineering assistance, manufacturing, and/or finishing services. These offerings help shorten production timelines and reduce production costs.
Advanced Stamping Capabilities
While specialization is good, narrow specialization is not. For example, some projects may not overtly indicate which metal stamping process is appropriate. A metal stamping company that offers a wide range of in-house stamping capabilities—e.g., bending, blanking, coining, piercing, etc.—is better able to accommodate such projects. However, for projects that required advanced metalworking—i.e., deep draw stamping—it is essential to work with a specialist to ensure greater precision and accuracy in the finished parts.
Tooling Design and Development Services
Metal stamping companies that maintain an in-house tooling design and development team have greater control over part and process quality. As they have the ability to create custom tooling for every project, they are better able to ensure production proceeds as intended.
Secondary Services
As indicated above, a metal stamping partner should ideally offer more than just metal stamping capabilities. These secondary operations—provided in-house or through a network of reliable vendors—allow clients to receive a full-service stamping solution. Some of the other fabrication and finishing processes a partner may offer include:
Heat treatment
Forming and welding
Painting and electrocoating
Passivation and sterilization
Pre-plating and post-plating processes
Precious and non-precious metalwork
Specialty edge cleaning and deburring
Assembly
Kitting & Custom Packaging
Industry Experience
Regardless of whether you [the customer] are in the aerospace, automotive, construction, appliance, or other industry, any potential metal stamping partner should have experience producing parts and products for your industry. This quality ensures the partner is familiar with any requirements or restrictions specific to the industry (e.g., using FDA compliant materials for medical devices).
Production Capacity
Both the type of equipment employed and the lead time for raw material orders estimated affect a company’s production capacity. A metal stamping partner should utilize metalworking equipment that allows them to complete projects efficiently without sacrificing precision or accuracy.
Quality Management
The International Organization for Standardization (ISO) develops and publishes standards aimed toward ensuring the quality, safety, and efficiency of products and services. The ISO 9000 family of standards focuses on quality management principles regarding a company’s products and processes. Companies certified to ISO 9001 comply with the ISO’s criteria for quality management systems, meaning they are knowledgeable about best practices regarding quality and sustainability, and are actively and adequately working to integrate them.

Posted by Keats Manufacturing on | Comments Off on Is Precision Metal Stamping Right for Your Application?
Precision metal stamping is a manufacturing process that utilizes a custom tool and die set installed in a stamping press to turn sheet metal into the desired components. It is used in a wide range of industries to create large quantities of parts and products with high precision, accuracy, and speed. While this process offers manufacturing advantages, it is not appropriate for every production project.
The following article discusses some of the considerations to keep in mind when determining whether precision metal stamping is right for your project. It provides an overview of the process, the benefits it offers, and the typical industries that use it.
An Overview of Precision Metal Stamping
Metal stamping—also sometimes referred to as pressing—relies on specialized tooling (i.e., a tool and die set) and equipment (i.e., a press) to form metal sheets and coils into the required shape and size. The pressure exerted on the workpiece by the press forces the material to conform to the shape formed by the tool and die. This process can occur in a single stage or across several stages, depending on the simplicity or complexity of the end product. Precision metal stamping operations largely rely on the use of automated equipment, which ensures the finished components are both precise and accurate.
In addition to higher precision and accuracy, some of the other advantages the precision metal stamping process demonstrates over other manufacturing processes include:
Greater product and process quality. Accuracy offered by the precision metal stamping process translates to a lower error rate during production. This means there is a smaller chance of producing faulty or flawed parts making it into the hands of customers.
Lower production costs. A generally automated process, precision metal stamping mitigates the need for manual labor. This quality also results in a lower error rate, which translates to less material utilization and waste during a production run.

Posted by Keats Manufacturing on | Comments Off on Aluminum Alloys for Metal Stamping
Aluminum alloys are grades of aluminum containing other elements that enhance the strength, durability, and other properties of pure aluminum. Adding different alloying elements allows the material to perform in a range of applications.
Elements often added to aluminum include:
Silicon
Iron
Magnesium
Copper
Zinc
Manganese
These elements can make up at least 15% of the final alloy by weight. Here we’ll explain the properties and types of aluminum alloys, as well as what makes a good alloy for metal stamping.
What Are Aluminum Alloys?
Aluminum alloys contain aluminum as the predominant metal along with other alloying elements. There are two major forms of aluminum alloys: wrought and cast alloys.
A cast aluminum alloy is an alloy that is melted in a furnace and poured into a mold to cool and solidify. Finished components have a low melting point, and the process creates cost-effective products. However, cast alloys generally have lower tensile strength than wrought alloys. Wrought aluminum alloysare alloys worked in solid form with the help of specialized tools. Aluminum stamping utilizes these alloys, which can be separated into two categories: wrought non-heat-treatable and wrought heat-treatable.
Cast and wrought aluminum have different identification systems. Cast aluminum alloys are identified by three digits followed by one decimal place. Wrought alloys follow a four-digit system, in which the first digit identifies the principal alloying element. The second digit, if not a 0, signifies a modification of the alloy, while the third and fourth digits identify the specific alloy. For non-heat-treatable alloys, a suffix is added to the number to indicate temper designation.
Aluminum Alloy Properties
One of the major benefits of aluminum alloys is their excellent strength-to-weight ratio: they are strong without being heavy. Because they are light, they are often used in commercial projects and transportation applications, where reduced weight results in cost savings.
Since they are light and effective, aluminum alloy parts last longer and require less raw material to make. These and the following characteristics make aluminum alloys ideal for metal stamping operations:
Thermal and electrical conductivity
Flexibility and malleability
Shiny, smooth finish requires little maintenance
Corrosion resistance
Strength at low and high temperatures
Types of Aluminum Alloys
There are three types of aluminum alloys:
Wrought non-heat-treatable
Made up of high-purity aluminum alloys (1xxx series), manganese alloys (3xxx series), and magnesium alloys (5xxx series), all of which are used for metal stamping
Hardened mainly through cold working
Wrought heat-treatable
Consists of copper, magnesium, or zinc as alloying elements
Includes 2xxx series, 6xxx series, and 7xxx series
Precipitation hardening enhances the alloy’s strength
Cast aluminum alloys
Includes non-heat-treatable and heat-treatable alloys
2xxx, 3xxx, 4xxx, 7xxx, 8xxx series
Strength levels are not as high as those of wrought heat-treatable alloys
Aluminum Alloys for Metal Stamping
Aluminum is available in various alloys and tempers. The best product varies by project. Here are a few factors to keep in mind when choosing an aluminum grade:
Level of workability or formability
Level of corrosion resistance
Strength level
Typical applications
Weldability or machinability
Type of heat treatment
These are the characteristics and applications of the common aluminum alloys used for metal stamping:

Posted by Keats Manufacturing on | Comments Off on Steel Alloys for Metal Stamping
Steel is one of the most widely used alloys and is comprised of carbon (less than 2%) and manganese (1%). Other small amounts of silicon, phosphorus, sulphur, and oxygen are also present. Steel is an integral component to almost all forms of production and construction, ranging from surgical equipment to household items.
This type of metal is 100% recyclable, and steel products last for approximately 40 years. It is produced from either the Blast Furnace Basic Oxygen Route (BF-BOF) or from the Electric Arc Furnace (EAF) route. Both of these routes contribute to the production of crude steel. The Blast Furnace Basic Furnace Oxygen Route utilizes the following to manufacture crude steel:
Iron ore
Coal
Limestone
Steel scrap
The Electric Arc Furnace Method utilizes all of these and electricity for crude steel manufacturing.
Since the magnetic properties remain unchanged, this metal can be continuously recycled. Recycled steel can serve as input for BF-BOF and EAP methods, contributing to the production of many new steel products. They contain approximately 37% of recycled steel. Because of its lightweight structure, cost efficiency, corrosion resistance, and energy efficiency, steel is used in almost every type of building and construction process. Applications constructed with this material include:
Automobiles
Buildings and infrastructure
Metal products
Mechanical/electrical equipment
Domestic appliances
Types of Steel Alloys
There are more than 3,500 grades of steel that are integral to engineering and construction projects. All contain forms of sulphur, phosphorus, and manganese. Manganese is beneficial to steel’s sustainability; however, too much phosphorus and sulphur in the alloy can have detrimental effects on steel’s durable properties.
There are four categories of this material:
Carbon Steels are used in 90% of steel production and contain trace elements of alloy products. They are classified into three subcategories: low, medium, and high. Low carbon steels contain up to 0.3% carbon, medium steels contain 0.3-0.6% carbon, and high steels contain more than 0.6%. They can be formed into a variety of shapes, ranging from Flat Sheet to Structural Beam.
Alloy Steels are used for pipelines, transformers, auto parts, power generators, and electric motors. Heat applications soften the material for welding and cutting applications. They contain:
Manganese
Silicon
Nickel
Titanium
Copper
Chromium
Aluminum
Stainless Steels are extremely resistant to corrosion, due to its high chromium content (10-20%). They are grouped into three subcategories, based on crystalline molecular structure:
Martensitic (cutting tools, dental, and surgical equipment)
Tool Steels are durable and heat resistant. The addition of tungsten, molybdenum, cobalt, and vanadium makes the raw material suitable for the production of dental and surgical equipment.
