Jun Xin is a professional manufacturer of thin-walled cup molds. The thin-walled cup molds we manufacture are round and square. The number of cavities ranges from 1 to 8 cavities, and the minimum wall thickness can reach 0.4mm, to ensure uniform wall thickness while ensuring the hardness of the cups.

Mould design:

Good mould design is the prerequisite for the manufacture of thin wall cup molds. Our company has a senior mold design team to analyze the mold structure and product structure in all aspects, including demolding angle, product surface miniature, pouring system, exhaust system, cooling system, etc. The most important and most prone problems of these molds will be repeated trials during mold structure design.

Cooling system design:

The design of the cooling system is a relatively complicated task, that is the cooling effect and uniformity of the cooling must be considered, and the influence of the cooling system on the overall structure of the mold must be considered. The specific location and size of the cooling system are determined; key parts such as the movable mold or cooling of inserts; cooling of side sliders and side cores; design of cooling elements and selection of cooling standard elements. By inserting BeCu into the mold to achieve rapid cooling, reduce the cooling time during injection molding, increase product production efficiency, and greatly reduce production costs.

Exhaust system design:

Thin-walled products have higher requirements for exhaust. In addition to avoiding surface burns and insufficient injection volume, excellent exhaust can also eliminate product defects and reduce mold pollution. We have rationally designed the venting method and size of the venting slot, which reduces the injection pressure and injection time, makes the molding of plastic parts easy, and reduces the energy consumption of the machine.

Mould steel selection:

S136 or H13 is generally recommended for fast thin wall cup molds. After quenching, the hardness of the core and cavity can reach HRC45-52, and the life of the mold can be improved, which is suitable for long-term efficient and stable operation.
