Designed with 8 independent cavities, the mold can produce 8 qualified plastic caps in one single injection cycle, greatly improving daily output and reducing unit production cost. The balanced cavity layout ensures uniform melt filling and consistent cooling for every cap, avoiding size deviation, weight difference and unqualified sealing problems in mass production.

1.2344 mold steel is famous for excellent toughness, thermal stability and wear resistance. After professional heat treatment to HRC 48-50, the mold core and cavity resist high-pressure and high-temperature impact during long-term HDPE injection. It is not easy to deform, crack or wear, effectively extending mold service life and lowering frequent maintenance costs.

The pin point gate structure enables fast and uniform HDPE melt filling. After molding, the gate breaks automatically during ejection, leaving almost invisible gate marks on the cap surface. No manual trimming or secondary processing is required, saving labor costs and ensuring neat and beautiful cap appearance. Meanwhile, it effectively prevents flash, shrinkage and short shot defects.

The core and cavity adopt high-precision polishing treatment. The smooth mold surface ensures easy demolding, no scratches, no flow lines and no rough texture on finished HDPE caps. All products present a glossy and clean surface, meeting high-standard food packaging appearance requirements.

The entire mold manufacturing process and steel material meet food contact safety standards. No harmful substances precipitate during production. The molded HDPE caps are safe and non-toxic, fully suitable for drinking water, food, condiment and edible oil packaging scenarios.

This HDPE cap mold is widely applicable for mass production of plastic caps for purified water bottles, beverage bottles, edible oil bottles, sauce jars, seasoning containers and other daily food packaging products, supporting long-term stable industrial continuous production.

We adopt strict CNC precision machining, standard heat treatment process and multi-layer quality inspection for every mold. Before delivery, full mold trial and testing are conducted to ensure stable operation, qualified product sealing performance, excellent appearance and ultra-long service life.

Q1: What plastic materials are compatible with this mold?

This mold is professionally optimized for food-grade HDPE materials. It can also adapt to similar plastic materials such as PP, which are commonly used for food packaging caps, ensuring stable molding and qualified product safety.

Q2: What is the service life of this 1.2344 steel cap mold?

With 1.2344 steel and HRC48-50 professional heat treatment, the mold has excellent wear resistance and stability. Under standard maintenance, its service life can reach 500,000 to 800,000 shots, suitable for long-term mass production.

Q3: Why choose pin point gate for plastic cap molds?

Pin point gate features fast filling speed, balanced melt flow and automatic gate separation during ejection. It leaves almost no trace on the cap surface, requires no manual trimming, greatly improves production efficiency and ensures uniform and beautiful cap appearance.

Q4: Is this mold fully compliant with food safety standards?

Yes. The 1.2344 mold steel is non-toxic and pollution-free, and the whole production process adopts food-grade production specifications. The molded HDPE caps have no harmful precipitation and fully meet food contact safety requirements.

Q5: Does the 1×8 cavity design cause unbalanced filling?

No. We adopt balanced runner layout and precise flow simulation before mold making. All 8 cavities achieve synchronous filling, consistent cooling and identical product size, weight and appearance, with zero unbalanced molding problems.
