3-D has been popular in mold design
3-D solid design greatly simplifies the standardization and synchronization between design and manufacturing, reduces errors, speeds up delivery, and achieves more reliable results. […]
Injection Molding Process
The fused materials in the mold cavity restore from viscous and fluid state to glassy state after being cooled. After complete cooling and molding, […]
What is Injection?
When the screw stops rotating and moves backward, the mold clamping part begins to work to close the mold and the injection unit subsequently moves forward to make the nozzle and mold spruing gate joint with each other; […]
Introduction To Plastication
The raw materials of plastics fall into the charging barrel from the hopper and are sent forward by the rotating screw. While in the charging barrel, the plastics, on the one hand, receive heating and warming from outside of the barrel, and on the other hand, are compacted due to the gradual reduction of the [...]
Screw Injection Molding Machine
The screw injection molding machine differentiates from the plunger injection molding machine mainly in that the horizontally-pushed plunger in the charging barrel is replaced by a rotary screw which undertakes all the fusion, plastication as well as injection of the materials in the charging barrel. […]
Plunger Injection Molding Machine
The plunger injection molding machine pushes forward the fused plastics in the charging barrel […]
Introduction to MPI
According to the TIR made by testing workers and the TVR by quality inspection department, the MPI (Manufacture Processing Instruction) can thereby be formulated, wherein the following aspects are included: […]
Mold Verify Report is very important
Mold Verify Report (TVR) is based on the products acquired from mold testing to assess whether corresponding molds reach the requirement through the measurement thereof. […]
Discuss deformation of plastic products during injection molding
The improper design for the structure of plastic parts, the incorrect setting of injection molding technical condition, inappropriate design of mold feed system, […]
How to solve ejector mark issue in injection molding
During ejection, white ejector mark usually appears on the plastic parts in contact with the ejector pin and such ejector mark will easily crack during actual use of the products. The causes thereof comprise: […]
