Custom parts of any machine are fabricated to the exact specifications and special requirements of the customer. Although the manufacturing process varies a lot, quality control of all these components is important. In this blog, we are going to share some of the different ways these custom parts are manufactured and the most effective ways to ensure quality.
1. CNC machining
CNC machining is a manufacturing process in which pre-programmed software is used to cut or move material. It can also fabricate metal as well as plastic parts with unparalleled precision.
A typical CNC machining process consists of six major steps. However, there are some limitations of using CNC machining. For instance, most CNC machines use circular tools, so the shape of the part is limited to curved corners due to the tooling. If you want to straighten the edges of a custom part, it will be difficult to do so in a CNC machine.
The CNC machine also has limitations in tool design, material selection, and minimum thickness of the part. A good inspection company in China can help you in this task.
2: Sheet Metal Fabrication
Sheet metal is a commonly used metal for fabrication because it can be used to make durable metal parts to customer specifications. With sheet metal fabrication, steel or aluminum sheets can be made into high-quality custom parts.
Sheet metal can be used to make parts in a variety of sizes. These parts are used in a variety of industries including furniture, construction, automotive, and aviation.
There are two main ways to manufacture sheet metal: cutting and forming. Cutting is the process of applying a force to separate the metal and modify the material into the desired shape. This force can be obtained by shearing, heating, or abrasion.
Stamping is a crucial process of placing a blank or coil of flat metal into a stamping press and forming the metal into a web on the surface of the tool and die. It is a fast as well as cost effective method of mass manufacturing.
Metal stamping is commonly used to manufacture parts for the automotive, medical and aerospace industries. As the global market grows, the demand for metal stamping is increasing due to the need to manufacture complex parts in high volumes and quickly.
A high degree of accuracy and repeatability in stamping can be achieved by programming the machine or through computer control. In addition, electrical discharge machining (EDM) and computer-aided design (CAD) programs are often used to ensure accuracy.
4: Injection Molding
Injection molding is an important process of fabricating parts by injecting molten material into a mold. This process provides optimal performance and cost effectiveness for high volume production parts.
Injection molding is ideal for high-volume production, such as mass production, where the same part is produced in rapid succession over and over again.
One of the main reasons for choosing injection molding is that it can be easily scaled up from small to large production runs. While the initial cost can be high, the price per unit can be greatly reduced, resulting in cost savings in mass production.
How do I ensure the quality of my custom parts?
The manufacture of custom components is often critical to a given product and their quality must be tightly controlled. That’s why you need to address quality issues through explicit incoming inspection prior to component assembly.
For example, during the pre-shipment inspection, our inspectors check the following points and perform some field tests to make sure you get what you ordered.
In addition, if a custom part is critical, a structural data sheet (CDF) can be created to check the part; CDF verification is a low-cost alternative to having every electronic part in your product tested by a professional lab.
With a professional pre-shipment inspection company, you can always ask them to inspect specific areas/points as you need them. The inspector will perform the inspection and generate a report to ensure the quality of the part meets your requirements.
