The characteristics of auto part molds:

1 .Large size: auto part like car bumpers, fenders, hoods, grilles, doors, backseats, front covers are in larges size, so the injection molds are need to be made in large size as well. This would require the injection mold makers to invest on large size machines.

2 .Complex surface: part with complex surface need to be machined by high speed and high precision CNC.

3 .High quality: There are many parts on a car, which are matched precisely. It requires not only accurate size, but also beautiful appearance and reliability. Especially lamps, instrument panel and other parts.

Mold flow analysis is highly recommended in design stage. For a long melt flow auto parts like car bumpers and grilles, application of mold flow analysis can provide the optimum gating solution and minimize injection molding cycle, multiple hot nozzles are employed frequently.

Mould steel:S136, NAK80, 738H, SKD61, P20, 718, 718H, 2738, 738, etc.

Plastic Material: ABS, PP, POM, PS, PVC, HDPE, HIPS, etc.

Mould base: LKM

Hot runner: YUDO, Mold Masters etc as specified.

Standard parts: DME, HASCO, etc.

Plastic injection molds for automobile

Tips of producing injection molds for plastic automotive components

1 .Automotive parts generally not only requires dimensions accuracy but high quality surface quality.

2 .In order to obtain high surface quality, parts are not allowed to have fusion lines/air lines and shrinkage marks on the surface. Therefore, the hot runner feeding system should be adopted to avoid the sharp angle affecting the flow in the mold design.

We uses good quality of steel S136,NAK80 and P20 for making cavities, cores and inserts of molds. We produce the molds of standards of DME,HASCO,MISUMI according to customer’s specification.

Mestech manufactures products from engineered resins (polycarbonates, GF nylons, PET, PP, etc.) to cosmetic parts such as acrylic instrument lens and bezels. Secondary operations such as sonic welding and pad printing are used as well.
