Special Shape Multi - Cavity Plastic Mould Parts For Plastic Insert Molding

Special Shape Multi - Cavity Plastic Mould Parts For Plastic Insert Molding​

When manufacturing plastic products via injection moulding, you can use either a single or a multi-cavity mould. What is the difference between the two and how can you choose the best one for your injection moulding project?
The difference between single-cavity and multi-cavity moulds.A single-cavity mould produces a single product per cycle, while a multi-cavity mould produces more than one product per cycle.

Product Detail

Pros of a multi-cavity mould
(1) The desired number of products will be finished sooner because of the shorter lead time per batch;
(2) You can produce more products with the same mould within the shot guarantee;
(3) A four-cavity mould has, in most cases, a lower total cost of ownership than four single-cavity moulds.
(4) More efficient use of the cycle time;
(5) Major scale benefits for stable processes;
(6) Lower part price.

Advantage

1) The product is large in batch size, and multiple molds can produce multiple workpieces in one injection cycle to improve efficiency.
2) The parts are small, but only larger injection molding machines are available. At this point, multiple parts can be placed in one mold for simultaneous production.
3) Each cavity must be in a state of stress balance as a whole, otherwise it will easily cause abnormal wear of the injection molding machine.
4) Pay attention to the balance of the runner casting system, with runner and gate control
5) One-mode multi-cavity is more complicated than single-cavity mold manufacturing, and the manufacturing price will increase according to the increase of the number of cavities.
