Precision Manufacturing Made Fast and Easy

by Carlo Padilla (Content Writer)

Manufacturing parts for products - from everyday objects to appliances, professional tools, and medical equipment and so on - is a complex process, especially when it comes to components with complex design and geometry. Luckily, modern-day technology makes it possible to mass-produce complex parts from a single image created using special software. To do this, there are several manufacturing processes available. Among the most popular are CNC machining, injection molding and die-casting. To find out which process best suits the needs of your business, let's go over each one.

Die-casting

Die-casting is a mass manufacturing process that shapes molten metals by injecting them into a mold cavity called ‘die’. Because the metal used in this process has to be liquefied, the most common materials are alloys with a low melting point such as zinc, magnesium and aluminum.

Die-cast alloys are very popularly used in automotive components such as wheels and engine parts because they are wear-resistant despite being lightweight – contributing to a vehicle’s durability and fuel economy.

Plastic injection molding

Similar to die-casting, plastic injection molding utilizes a mold to create parts but with molten plastic instead of metal. Thermoplastics – polymers that can be molten and solidified repeatedly such as PP, PE, PVC and ABS – are typically used for this process. Injection molding machines can produce parts with impeccable precision and compliance to customer specifications – and are able to do so thousands or even millions of times in succession, hence the method’s adoption by millions of manufacturing companies.

Sourcing

Choosing which manufacturing process is right for your business ultimately depends on the material requirements for your parts. Through Global Sources, you can find certified manufacturers that offer the production of these parts for competitive prices and reasonable lead times. Check out a few samples as follows.
