30Ton Clamp Forces Cold Runner Injection Molding For Electronic Products

Custom Plastic Cold Runner Injection Molding For Electronic Products

1 . We are a direct manufacturer specialized in OEM plastic products from design to rapid prototype to mould to production for more than15 years.

2 . Material: all kinds of plastic, such as ABS, PC+ABS, Acrylic, PVC, TPE, PBT, PC, PE, PP, PPS, PA, POM and all other engineering plastics with or without additives.

3 . Providing samples with important dimensions and customizing inspection report, material certification to customer for validation and verification.

4 . Normal dimension is controlled according to middle class tolerance specified in ISO and DIN.

Cold runner injection molding systems consist of two or three plates contained within the mold. The system injects the plastic into the mold through the sprue and feeds the runners, which lead to the parts in the mold cavity.

Nozzles. The nozzles can vary from vendor to vendor. The user must dispose of welded assemblies if any type of particulate penetrates the water jacket. Some nozzles have removable water jackets that allow for cleaning.
Nozzle Tips. Some manufacturers mount the nozzle tips securely to the end of the nozzle. Other vendors offer spring-loaded nozzle tips, which allows for thermal expansion of the mold when heated, which keeps the nozzle in constant contact and prevents leakages.
Runner Manifolds. Be aware that cold runner systems that have a gun-drilled runner manifold design tend to have “dead spots” at the end of the channels, where the material has cured and becomes hard to clean. Conversely, manifolds with a split-plate runner design allow the user to disassemble the plates for cleaning. It also allows for quick material and color changes.
Piston Assembly. Some systems rely on external air lines and barb fittings, but gun-drilled air passage ways eliminate the need for air hoses and barb fittings for each nozzle, which prevents damage to the air lines and connection errors.
Pneumatic Connections. Cold runner systems have either external air lines or an air terminal box with a quick disconnect coupler. The mating umbilical cord abuts with the molding machine to make the required connection from the valve gate controller to the cold runner system.
