Thin wall mould design key points Jan 02, 2018


Seaco Mould is thin-walled products mold professional manufacturer, product design, should pay attention to the following major points:

1. Seal water surface design zero with zero.

2 box and the cover assembly ,the mating surface empty 0.15-0.2mm gap.

3. Cover edge and the box body fit, the design of space-time 0.8-1mm, specifically to see product size.

4. Ribs design generally thinner than the product, most of the ultra-thin products are transparent material,ribs tend to be too thick bubble.

Thin-walled products,Mold structure design points:

1. The shape of the product is simple, without any undercut and touch holes, similar to the cup, the product surface more than 3 degrees, can be designed as a side gas, oblique gas, valves and so on.

2. Stripper board height 1mm below, for the processing of ribs, stripper can be inserted.

3. Multi-cavity mold design methods: (1) Independent self-locking: multi-cavity independent self-locking Suitable for all shapes thin-wall class mold design, each cavity independent, the bottom of the mandrel seed into the core composite board. (2) the overall clamping: the wall thickness greater than 0.8mm, the machine is relatively small, hard to put in, the overall structure, but to be explained in advance.

4. Cavity, core structure design: (1), cavity composite plate generally used P20 steel. (2) The cavity at the bottom of the single-chamber barrel structure is empty, and the steel plate with 45mm height above the press plate must be ensured. Prevent the cavity to produce flash. (3), the cavity along the mouth with inserts, to reduce the cavity thin steel cracking. (4) gate inlet water jacket, reducing hot runner cooling time.
