Plastic Enclosures for Controller Unit

Dongguan Shenghua Plastic Mould has rich experience on tooling and injection molding plastic enclosures for various applications, such as electrical products, electronics products, hand-held devices, telecommunication devices and etc.

Plastic material used for custom enclosures are mainly ABS, PC+ABS, PC, PA66, Nylon/PA + Glass Fiber. Plastic material can be fire proof or retardant standard (UL 94 – V0).

We have 12 injection machines, ranging from 50 ton up to 450 ton, and can mold single part up to 1.5 kilograms in weight. Our injection shop runs on 2 shifts, 7 days a week.

Plastic Injection Molded Parts Quality Control Procedures We Follow:

1. Machine Inspection (On-The-Spot Inspection)

Parts are initially inspected directly out of our molding machine. Our machine operators are trained to identify and rectify the following defects:

1.1.Sink marks that form when the outer plastic shell hardens before the internal plastic has had an opportunity to cool.

1.2.Short shots caused when there is an inadequate amount of plastic material to fill the mold.

1.3.Burn marks caused by trapped compressed air during the molding process.

1.4.Flash marks, which is the excess plastic that extends from the end of the molded part

2. Finishing Station Inspection

Parts at the finishing station are inspected for consistent finishes and textures prior to silkscreen or pad printing.

3. Quality Control Department Inspection

Finished parts undergo one final inspection to ensure tolerances are met for every part. Optical projector and digital calipers measure for part accuracy to within =/-.005mm.

Why You Should Also Consider Importing Injection Molds to Your Own Country for Mass Production?

Not ALL plastic injection molds are necessarily cheaper to stay in China for mass part production, otherwise China would not have become the world’s largest mold exporter.

The following conditions will justify your bringing the molds to your own country for mass production:

1. High production volume and the plastic product is bulky, which translates to high transportation cost, even by ocean shipment.
    
2. Plastic products that do not require lots of labor for assembly, or assembly with many other non-plastic components.
    
3. Plastic product that calls for very short delivery time.
    
4. Plastic products that do not require silkscreen printing, pad printing, heat transfer printing or any other secondary treatments.

If the plastic part or product you intend to develop and produce falls under none of the above conditions, the chances are that it’s better to leave the injection molds in China for production.
