(3) hot runner mold: This mold construction and fine nozzle substantially the same, the biggest difference is that the flow channel in one or more climate of the manifold plate and the heat pump in his mouth, no cold feed stripping, and pouring runner port directly on the product, so the runner does not require a release. This system is also known as the contact angle method without intake system, saving raw materials for raw materials more expensive, higher product requirements, the design and processing difficulties, tooling costs high. Hot runner systems, also known as hot runner system, mainly composed of hot sprue bush, hot runner plate, thermostat electrical box. The most common hot runner system with a single point and multi-point hot runner thermal gate two forms. Single-point hot runner is directly injected into the molten plastic cavity hot runner with a single set, it applies to a single gate single cavity plastic mold; multi-point hot runner hot runner plate by molten material to the respective branches Heat and sprue bush and then into the cavity, which applies to single-chamber or multi-cavity mold into the material compression molding commonly known pressing contact angle is one of the oldest methods of molding plastic parts. Compression molding is added directly to the plastic mold cavity has a temperature of open and closed mold under heat and pressure melt the plastic into a flow state. Because of the physical and chemical effects contact angle meter, leaving the plastic hardened into a certain shape and size of the room temperature is kept constant plastic parts. Compression molding is mainly used for forming a contact angle meter thermosetting plastic, such as phenolic molding powder, urea-formaldehyde and melamine-formaldehyde molding powder, glass fiber reinforced phenolic, epoxy, DAP resins, silicone resins, polyimide, etc. molded plastic, also forming unsaturated polyester dough (DMC), sheet molding compound (SMC), BMC (BMC) and the like. Under normal circumstances, often with the structure by compressing the film, the lower mold, the compression mold into an overflow, no overflow, semi-overflow-type categories.
