Capacity of Research and Development
KINGSMAN has a powerful team for research and development, which is capable of manufacturing the perform molds with one cavity to ninety-six cavities including the injection system. At the same time we can manufacture perform molds especially according to customers' injection molding machines. We also design cold parts, hot runners and other main exchangeable components to fix on the imported perform molds.
Mold Features
1. Features of the perform mold. No cutting of valve gate is employed to reduce the labor cost.
2. Advanced hot runner system assures lower level of AA value.
3. Reasonable- designed cold water channels increase cooling effect and shorten the cycle time.
When thermoplastics are moulded, typically pelletised raw material is fed through a hopper into a heated barrel with a reciprocating screw. Upon entrance to the barrel, the temperature increases and the Van der Waals forces that resist relative flow of individual chains are weakened as a result of increased space between molecules at higher thermal energy states. This process reduces its viscosity, which enables the polymer to flow with the driving force of the injection unit. The screw delivers the raw material forward, mixes and homogenises the thermal and viscous distributions of the polymer, and reduces the required heating time by mechanically shearing the material and adding a significant amount of frictional heating to the polymer. The material feeds forward through a check valve and collects at the front of the screw into a volume known as a shot. A shot is the volume of material that is used to fill the mould cavity, compensate for shrinkage, and provide a cushion (approximately 10% of the total shot volume, which remains in the barrel and prevents the screw from bottoming out) to transfer pressure from the screw to the mould cavity. When enough material has gathered, the material is forced at high pressure and velocity into the part forming cavity. The exact amount of shrinkage is a function of the resin being used, and can be relatively predictable.To prevent spikes in pressure, the process normally uses a transfer position corresponding to a 95–98% full cavity where the screw shifts from a constant velocity to a constant pressure control.
