Improper cooling water channels affect product quality and production efficiency

Cooling water channels need a uniform and efficient layout

Molds & Tooling cooling water channelscooling uniformitymold design

Product breaks unevenly at the gate

Gate breaking requires optimizing gate size and cooling

Molds & Tooling gate breakinggate designcooling

Runner cross-section, length, and layout design unreasonable

Runners need balanced layout and appropriate cross-section

Molds & Tooling runner designcross-sectionlayoutcold slug well

Product has silver streaks, poor plasticization, or unstable color

Back pressure needs to match speed, balancing venting and shear

Molds & Tooling back pressureventingshearplasticization

Cold slug marks appear on the product surface

Cold slug marks require increasing nozzle temperature and reducing cold slug sources

Gate type, size, and position design affect product quality

The gate needs to be reasonably designed according to material and product

Molds & Tooling gate designgate typegate position

Product deforms on demolding or dimensions unstable

Cooling time needs to be reasonably set according to material and wall thickness

Product has sink marks, unstable dimensions, or flash

Holding pressure needs to be set according to shrinkage rate and gate freezing time

Improper draft angle design, product sticking to mold or deforming

Draft angle needs to be designed according to shrinkage rate and product depth

Wall thickness >5mm thick-walled products have prominent sink marks and bubble problems

Thick walls require extended holding pressure and cooling time
