Advanced Mold Design & Craftsmanship
The mold adopts a scientific 1*2 cavity layout, which balances production efficiency and mold operating stability, avoiding cavity unbalance and product dimensional deviation caused by multi-cavity crowding. The 2-pin point gating design is reasonably distributed according to the fluidity characteristics of PP and TPE materials, ensuring uniform melt filling, effectively reducing internal stress of products, and preventing warping, shrinkage and cracking of PP/TPE molded parts.
Made of 1.2344 high-quality mold steel with precise vacuum quenching and tempering treatment to achieve HRC 48-52 standard hardness. This process greatly improves the mold’s high-temperature resistance, fatigue resistance and abrasion resistance, enabling the mold to maintain high precision and stability under long-term continuous injection molding working conditions and extend the overall mold service life. Both front and back mold surfaces are finely processed with standard VDI 24# texture, with uniform texture depth and clear grain, making the finished plastic products have delicate hand feel, beautiful appearance and strong anti-scratch performance.
In addition, the mold is optimized with a high-efficiency cooling water channel system, which accelerates product cooling and shaping, shortens molding cycle time, and significantly improves production capacity while ensuring product dimensional accuracy. The overall mold structure is reasonable, with precise matching of moving and fixed molds, low failure rate, and convenient later maintenance and repair.
Material Adaptability & Product Advantages
This mold is specially optimized for the molding characteristics of PP and TPE materials. PP material has the advantages of light weight, corrosion resistance and good toughness, while TPE material features soft touch, environmental protection, non-toxicity and good flexibility. The customized gating and cooling system perfectly adapts to the different melting and cooling characteristics of the two materials, realizing one-time precise molding of PP hard parts and TPE soft parts composite products.
Compared with ordinary molds, this 1.2344 high-hardness mold has stronger pressure resistance and deformation resistance, no burrs, no shrinkage depressions on the surface of molded products, and consistent VDI 24# texture effect in batches. The 2-cavity design doubles the production efficiency on the premise of ensuring product quality, greatly reducing production costs for customers.
Application Scenarios
This high-precision PP & TPE injection mold is widely used in various industries requiring soft and hard rubber plastic parts production, including daily consumer goods, electronic accessory parts, household appliance plastic parts, automotive small plastic parts, medical auxiliary plastic parts, toy accessories and other fields. It is suitable for customers who pursue high product appearance requirements, stable batch quality and high production efficiency.
Quality Assurance & After-sales Service
All molds are strictly manufactured in accordance with international injection mold standards, through multiple precision testing processes including hardness testing, dimensional inspection, mold trial testing and surface texture inspection. Every mold will complete sample confirmation before delivery to ensure stable molding and qualified product appearance and size. We provide professional mold after-sales support, including mold maintenance guidance, technical support and follow-up modification services, to ensure long-term stable operation of customer production lines
