Attention rules for injection mold design
1. Mold opening direction and parting line Each injection product must first determine its mold opening direction and parting line at the beginning of the design to ensure that the core-pulling slider mechanism is minimized and the effect of the parting line on the appearance is eliminated. 1) Af...Read more -

The process from mold design to mold trial (part 2)
In the last article, we talked about the part1 part of the mold design to the trial mold process, and then we will continue to explain it to you. 2. Proofreading, reviewing, tracing, and sending photos (1) The relationship between the mold and its parts and the drawing of the plastic part Whether...Read more -
Explanation of the process from mold design to mold trial
Draw mold diagram Before drawing the mold assembly drawing, the process drawing should be drawn, and it should meet the requirements of the part drawing and process data. The size guaranteed by the next process should be marked with the words “process size” on the drawing. If aft...Read more -
Top Ten Problems of Mold Trial
Common problems in mold trial 1: The main runner sticks to the mold The method and order of solving the problem: 1 Polishing the main runner → 2 nozzles coincide with the center of the mold → 3 lowering the mold temperature → 4 shortening the injection time → 5 increasing the cooling time → 6 che...Read more -
How does the “burr” of the injection mold occur?
Injection molding products refer to plastics that are heated, plasticized and melted by an injection molding machine, and then injected into the cavity of a molding mold for molding. After cooling down, the melt is solidified and demolded, and the injection molding machine is injection molded. Fl...Read more -
The 5 effects of mold temperature on the quality control of injection molded parts
1. The influence of mold temperature on product appearance Higher temperature can improve the fluidity of the resin, which usually makes the surface of the part smooth and shiny, especially to improve the surface beauty of glass fiber reinforced resin parts. It also improves the strength and appe...Read more -

Selection and installation of injection mold pressure sensor
The pressure sensor can be installed in the nozzle of the injection molding machine, the hot runner system, the cold runner system and the cavity of the mold. It can measure the plastic from the injection molding machine nozzle to the Plastic pressure somewhere between the mold cavities. This dat...Read more -
Analysis of the problems and causes of the injection mold!
The deformation, bending and twisting of deformed products are mainly due to the fact that the shrinkage rate in the flow direction is larger than that in the vertical direction during plastic molding, which causes the parts to be warped due to different shrinkage rates in each direction. It is a...Read more -
