Mould name:Preform Mould?Shaping Mode:Blow MouldPreform Mold, Preform Molding, Preform Moulding, Preform Molds, Preform MouldsHow preform mold is good?What is the impact of hot runner nozzles select it, I learned a little of the following: product quality, product design, plastic raw materials, molds, cycle time, gates, nozzles, runner, temperature controller, and an injection molding machine performance and so on. When we have a very accurate understanding of these, it is possible to choose the right for a hot runner nozzle. Choosing the right preform mold?1, product weight: different weight for hot runner product requirements are completely different.2, plastic raw materials: Different materials have different Plastic processing variables, those variables will affect the choice of processing hot runner system.3, mold: Cavity like how much? Distribution nozzle distance how? Processing what kind of material? Etc. These are related with the optional hot runner system mold elements.4. cycle: rapid production cycle means increased nozzle requirements. For example, the nozzle to accurately transfer the heat, but also durable.5, gate: For point-gate, in order to maintain a good balance of heat in each molding cycle, the sharp-tongued heat must have melted seal material and cooling functions. The valve gate is used mechanical methods to seal the gate.6, the nozzle: nozzle size can be general, temperature distribution, physical characteristics, the materials (copper, steel, etc.) as well as ease of maintenance and price make that distinction.7, the flow path: use the hot runner system avoids the generation of the material, thereby saving raw materials, while eliminating the need to manually in the past, robots or other means to remove the feeding process.8, the temperature control: Each nozzle must be connected to a relatively complex temperature controller9, performance injection molding machine: the ability to install a given size die, to provide sufficient clamping forc
