According to the difference of the pouring system,
the type of plastic mold is as follows.
1. The edge gate mould. The runner and gate on the parting line. They are stripping together with the product when open the mould. The design the most simple and easy processing, low cost, so many manufacturers use the edge gate mould to production-manufacturing.
2. The pin-point gate mould. Runner and gate is not on the parting line, generally on the product, so the design of a set of gate parting line, the design is more complex, processing difficulties, the general according to the requirements of the product to determine whether the use of pin-point gate mould.
3. Hot runner mould. This kind of mold structure is roughly the same as pin-point gate mould, the biggest difference is the runner in one or more of the constant temperature hot manifold and hot sprue, not have cold material demoulding, runner and gate directly on the product, so the runner does not need to release. This system is also known as the no-gate system, can save raw materials, applicable to the more expensive raw materials, higher requirements of the situation,
plastic mold parts design and processing is difficult, the cost is higher.
