The injection molds designed and produced by KRMODL are compatible with a variety of different types of raw material processing requirements, such as PP/PPE Injection Molding, ABS Injection Molding, PC Injection Molding, TPU/TPE Injection Molding, PEEK/PEI Injection Molding and Silicone Rubber Molded. Common injection molding raw materials and mold features:
1.ABS
Excellent overall performance, impact resistance, heat resistance and easy processing, low shrinkage. For ABS raw material injection molding design, attention should be paid to the design of the gating system and cooling system. The runner should be short and thick. The gate can be selected from the side gate, point gate or latent gate to balance the fluidity and surface quality. The cooling water channel should be evenly distributed, 10-15mm away from the cavity surface to avoid interference with the ejection mechanism.
2.PP
Semi-crystalline material, excellent fluidity, high shrinkage, chemical corrosion resistance but poor high temperature resistance. When designing injection molds, it is necessary to avoid direct gates. Needle gates or hot runners are recommended. The raw materials of injection molds are usually pre-hardened steel or aluminum alloy. Nitrided steel can be selected when wear resistance is high.
3. PC
High transparency and strong impact resistance, but high melt viscosity, easy hydrolysis, and narrow molding temperature range. The runners and gates of the injection mold need to be wide. Fan-shaped gates are recommended to reduce flow resistance. The mold material usually chooses S136 high mirror polished mold steel, and avoids the use of release agents to prevent surface defects.
