Kaihua Innovative Technology(06): Low Pressure Injection Molding
1.What is low pressure injection molding The low-pressure injection molding process is a packaging process that uses a very low injection pressure (0.15-4MPa) to inject the hot-melt material into the mold and quickly solidifies it. Temperature, impact resistance, vibration reduction, moisture-pr...Read more -
Kaihua Innovative Technology(05): Stack Mould
Different from conventional molds, the cavity of the stack mould is distributed on two or more layers, which is equivalent to stacking and combining multiple molds together. The most common two-layer die stack is usually installed by two single-layer dies back-to-back, and the parting surface is ...Read more -
Steel to Plastc Promotes Automotive Lightweight
Steel to plastic mainly uses engineering plastics such as PP, PC and ABS to replace traditional steel as aotomotive’s body parts, reducing the weight of the whole vehicle to 1/4-1/8 of the original weight, and realizing the lightweight of the vehicle, meanwhile reducing vehicle fuel consumption. ...Read more -
Injection Technology of Thin Wall
When the wall thickness is less than 1mm in injection molds, it is called thin wall, and a more comprehensive definition of thin wall is length-thickness ratio L/T (L: the process from the main flow of the mold to the farthest point of the finished product; T: the thickn...Read more -
Gas assistance
Gas assistance refers to the use of high-pressure inert gas (N2) injected into the molten plastic to form a vacuum section and push the molten material forward to realize the processes of injection, holding, and cooling. Due to gas has efficient pressure transitivity, it keeps the pressure consis...Read more -
