Plastic Pump Mold
Plastic pump molds are specialized molds used in the injection molding process to produce various types of plastic pump components.
These molds have specific features tailored to meet the requirements of pump manufacturing.
DSW is a manufacturing company in Ningbo City, China, with 50 years of experience in plastic pump mold, and plastic injection molding.
We are experts in plastic pump mould, insert molding, over-moulding, and custom injection molding.
The key problem in making a plastic pump mold, it is important to identify the specific issue that is being faced.
For instance, if the mold cavity cannot be completely filled, it could be due to low die temperature, material temperature, or injection pressure and speed, uneven plasticization of raw materials, poor exhaust, insufficient liquidity of raw materials, or premature curing of polymer melt due to unreasonable structural design.
Similarly, if air is trapped in the cavity to create bubbles in the part, it could be due to the air being unable to escape from the parting surface, the ram, or the vent when the two melt fronts meet.
Therefore, it is important to analyze the causes of the problem and propose related solutions.
The solutions could range from using more fluid materials, filling the thick wall before filling the thin wall, increasing the number of gates and runner size, reducing thickness inconsistency, ensuring uniform wall thickness, adding a vent at the last filled place, redesigning the gate and runner system, increasing injection pressure and injection speed, increasing the amount of injection, increasing material cylinder temperature and mold temperature, and more .
