The metal processing industry uses different materials to produce durable and efficient products for other purposes. However, the best metal will meet the requirements of that particular application and the final product's design specifications. Below, we describe what to consider in the selection process for metal fabrication parts and features influencing your workload.
Before deciding on the kind of materials to use for your manufacturing, make sure that you try to understand the application that your manufactured products will be subjected to and the conditions that they are likely to encounter. Also, it is important to consider material characteristics, including, but not limited to, machinability, weldability, etc.
The machinability definition applies to how easily a given metal type can be cut (machined). The lower the cost of cutting metal, the less cost you will have for your project. However, you also do not want to cut your metal of choice in a way that is unacceptable or will not yield the desired outcome. Among the above alloys, steels exhibit some of the easiest machinability. On the other end of the discussion, some of the most challenging materials for the machine are found in stainless steel. Therefore, high-quality cutting parts are likely to be required to finish the cutting of the metal properly.
That being said, weldability is a term that directly relates to the metal's inherent ability to weld with similar other metals and any other material. With the diffusion welding process, several metals can be welded, and you can have your final result for the task you intend to accomplish. Hence, how weldable the metal you plan to use in your project is. In other words, does the metal need a lot of preparation before it gets ready for welding?
Furthermore, will it demand the use of sophisticated equipment and welding procedures? If so, you might have to add the inevitable expenses of such a decision. Steel is the most recommended metal for straightforward metals to be welded.
Mention metal on any given day, and it can be ascertained that, given the right time and condition, the material rusts. So, the term corrosion resistance indicates which end metal is resistant to corrosion. The process, which involves oxidation and exposure to chemicals, causes corrosion. Thus, if the result of your project is aligned with such exposure, then you need to contemplate a type of metal that corrodes less than others.
Tensile strength, on the other hand, refers to the ability of a metal type to endure a certain amount of stress or tension beyond which it will be irreversibly deformed and fail. In other words, the tensile strength describes the resistance of a metal to stress in general. Thus, tensile strength is quite helpful in determining the metals' stability because of their strength.
If you have an idea of what to expect with the different types of metals of this kind, you will be in a much better position to select the most appropriate metal for the type of project you have in mind. In contrast, aluminum has some of the lowest tensile strength among all metals. Stainless steel, on the other hand, has some of the best.
Can your chosen metal be easily combined with other materials if required? Of course, you should not select a particular type of metal that will give you trouble while fabricating your project.
However, if the whole project you are working on is made from the particular metal you chose, it is an entirely different story. Of course, you do not have to consider such interaction with other materials. But if you are constructing something, let's say a house, then there are some qualities that the metal you are using must have: it should be long-lasting, durable, easy to work with, and adaptable.
As mentioned, there are many categories of metals that you can use in your project, ranging from aluminum to stainless steel. Here, we briefly describe the most prevalent metals you will likely encounter while looking for a suitable material.
Steel is an alloy of carbon and iron. Carbon is the crucial alloy material that provides steel with tensile strength and hardness. Steel produces arms, ammunition, machinery, vehicles, buildings, and bridges. Moreover, steel types include stainless steel and carbon steel; according to their properties, both are used in different fields.
Copper is also characterized by good electrical conductivity, high flexibility, and corrosion resistance. Therefore, this metal application is widely seen in industries and the marine sector.
This metal is suited to applications where it has to withstand low temperatures, like refrigerators. Aluminum is lightweight and robust but should not be used above 392°F (200°C).
It is a metal characterized by low density and is commonly referred to as magnesium. This makes it ideal for vehicle parts and airplane manufacturing industries.
In manufacturing, keeping an operation profitable heavily depends on minimizing operating costs. This is even more important in high-volume manufacturing. Choosing the proper manufacturing technique is vital as it can make the process budget-friendly and increase efficiency by faster turnaround time. Metal stamping is an extensively preferred technique in the production quarter because of its price effectiveness. In this weblog, we can explain what makes steel stamping so cost-effective and some precautions that a manufacturer must recognize about this steel forming approach to ensure exceptional products. Understanding Metal Stamping Metal stamping is classified as a precision manufacturing process. The procedure includes urgent or stamping a shaped die on a metallic sheet to make a simple or complicated element. The process starts by feeding sheet metal into the stamping machine, after which the die is pressed on the sheet to reduce the specified shape. Standard metal stamping procedures also involve punching, bending, and embossing. Countless simple items can be made through metal stamping, such as cigarette lighters, drink cans, gun bullets, and solid gold jewelry. Why is Metal Stamping Cost-effective? Tooling Costs are Lower A significant reason operating costs are lower in a metal stamping operation is the lower tooling cost. Metal stamping is much more critical than other manufacturing methods because a single die is the most effective in making a custom shape. Different production techniques require separate molds or tooling for each character product. Fast Lead Time In metal stamping, the manufacturing cycle is much faster than in other production techniques like molding. As the die is already shaped accordingly, the manufacturing step only consists of pressing it on the metal sheet, which takes much less time than other methods. Hence, more units can be manufactured in a short amount of time, which reduces per-unit cost. Material Wastage is lesser Material wastage is a significant expense since metal sheets are expensive. Metal stamping helps reduce material wastage because the custom-shaped die is designed to press precisely on the sheet and has the correct dimensions for maximum unit production, ensuring that every metal sheet is utilized thoroughly. Design Flexibility Metal stamping techniques stand out because even complex-shaped products in various sizes can be produced quickly with a limited tooling setup. For startup manufacturing firms, this means a more excellent range of products with minimal setup investment. Parts Replacement Costs are Low Machine breakdown seldom occurs in metal stamping since the most crucial part, the die, does not need frequent replacement and can produce high output for a long time without getting worn down. Quality Control in Metal Stamping High-quality control is vital in metal stamping to prevent faults in metal parts design specs. ISO 9001:2015 section 3.6.2 defines quality as the extent to which an item's set of inbuilt homes fulfills requirements. Product quality can make or break a manufacturer's reputation, so implementing a quality assurance program in a metal stamping business is crucial. Moreover, a well-implemented quality assurance program enhances efficiency and productivity and eliminates product recalls, leading to time delays and additional costs. Prefabrication Inspections The prefabrication process starts with an inspection of the raw materials. They should have the properties required to satisfy the part specifications. An FMEA follows this. This systemic evaluation determines where and how the fabrication process could fail and evaluates the relative impact of various failures to identify the methods that require adjustments. APQP also applies to prefabrication inspection. It involves formulating a framework of manufacturing procedures and techniques that are satisfactory to the client. Fabrication Process Control This quality control procedure involves documenting and recording fabrication in real-time. The following list of standards are required. ● Pressure Equipment Directive (PED) ● Restriction of Hazardous Substances (RoHS) ● ISO 9001:2015 ● International Traffic in Arms Regulations (ITAR) ● Military Specifications (Mil-Spec) ● Internal quality policies Post Fabrication Confirmation The quality control system should cover the entire metal stamping process, so the final quality control measure involves 3D scanning to finish the quality inspection. Quality Testing Technology Used in Metal Stamping Statistical Process Control These systems use various machines and instruments to measure and control quality. Optical Vision Systems Such systems record exact measurements of stamp parts. For instance, a 2-axis optical comparator inspects the dimensions of a manufactured part. Functional and Custom Gauges Functional gauges are used to quickly check finished parts and determine if they are fit for assembly. Custom gauges develop design and quality standards for stamped parts. Digital Measuring Machines with Metrology Software Digital measurement machines enhance quality assurance by improving precision, speed efficiency, and control over what one measures. The metrology software engages optical gaging products to operate and maintain every measurement action to display and report. CMM Measurement and Layout Capability A coordinate measuring machine helps obtain measurements of physical objects by determining discrete points on the object's surface. For instance, our Brown & Sharpe CMM is part of a popular series ensuring that measurements are always high-speed and highly accurate. Reverse Engineering CAD Software Reverse engineering CAD software constructs a 3D CAD model of a natural part. The computer-aided program captures millions of data points and accurately measures the most complicated product. Conclusion The secret of metallic stamping efficiency lies in high-speed production and the capacity to cut targeted shapes without any wastage. Moreover, metal stamping can be effortlessly automated, bringing down labor prices. Metal stamping is also very smooth to upscale, which means that it is simple to increase production ability without a variety of funding sources.
READ FULLThere are different ways of manufacturing metal parts, and precision die casting is one of them. There are various reasons why people use this method. You can easily understand what makes it different from the standard die-casting method from its name. The precision level it gives is not possible based on the standard procedure. So, let’s find out what it is and how it works, What is Precision Die Casting? It is a method where metal dies are used to manufacture metal parts. The injection process takes place in it, where the molten metal is transformed into a required shape with cavities and other details. Its higher precision makes it better than ordinary die casting. The accuracy level in it is superior, which is why many parts are manufactured through it. Here are the advantages of using precision die casting. ● The parts that are manufactured using this method do not require further enhancement. ● Their tolerance level is higher than standard die-casting. ● You will find thin walls in them because of high precision. ● You will not find defects or the slightest chance of finding a few. ● Complex parts get better results when this method is used. Common Materials Not every material or metal is compatible with precision die casting; some are specific. Soft metals that can be easily molded inside a die have a lower heating point than metals like stainless steel and titanium. This is why soft metals are suitable for precision and die casting with moderate heating points. ●Aluminum ● Zinc alloys ● Tin alloys ● Magnesium alloys Many parts are manufactured with them because of their low heating point and lighter weight. Since aircraft and automobiles need lightweight parts, these metals are suitable for those applications. Their soft nature makes them an adequate choice for precision die casting. Procedure/ Types of Procedures of Die Casting The procedure is similar to standard die casting. In precision die casting, the die is more complicated with thin walls, which is why the accuracy and uniformity levels are higher in this method. The procedure is simple here, with a few steps followed without any complexity. Metal die formation The first step is to form a metal die, where the size, cavity, walls, and designs are selected. Rigid metal is used for its formation because of its high heating point. This metal die is different from the standard type because its detailing is sharper and more complicated. Molten metal production in furnace Then, molten metal is produced, which is supposed to be injected inside the die. The molten metal is either a single type or an alloy. This process has to take place inside a furnace, where the right amount of temperature is maintained to keep the molten form active. Injecting the molten metal through a piston Then, it is injected inside the die through a piston connected to the die. The piston presses it to fill the die completely, giving it the right shape and other details. Cooling process Then, the cooling process starts, and the mold is allowed to cool down. It takes a few minutes, and the molten metal takes the desired shape from the die. Ejecting the part from the die Lastly, the ejection occurs when the metal part is complete. The die is ready to release the metal part inside it. Finishing part “If required” Since it gives precise production, there is no need to do extra work unless there is any flaw or excessive layer. The overall quality of the metal part is accurate in terms of design and size. Applications Of Precision Die Casting Various industries use this method for the bulk production of metal parts at low cost. They don’t use any modern machinery to achieve precision since this precision die casting is enough. Since all machines, automobiles, and aircraft of the same model need uniform parts, industries rely heavily on this method. The precision level makes this method an evergreen type for everyone. ● Auto parts ● Machine parts ● Aircraft parts ● Surgical equipment ● General appliances’ shells or frames Advantages Of Precision Die Casting Some prime advantages make this method stand out in industrial ways. These advantages are the optimum needs of all industries. Since every sector wants all the metal parts in the exact and accurate sizes, you can expect that from this method. ● Precision ● Uniformity ● Strength ● Complex designs Conclusion This was all about precision die casting, from production to advantages. People who are either involved in the production or procurement process know how essential this method is. It is also one of the most cost-effective methods used in the industry.
