In outdoor electronic devices, automotive parts, building components, and household appliances, plastic shells are exposed to sunlight, rain, and temperature fluctuations for extended periods. UV radiation is the primary factor leading to material perform
Precision mold, as the "mother machine" of industrial production, transforms design blueprints into reality with manufacturing precision at the micrometer or even sub-micrometer level, truly embodying industrial art that blends materials science, mechanic
The structural design of non-standard customized plastic shells must fully consider the simplicity and automation of the assembly process.
The mold surface needs to be polished to reduce surface roughness, reduce gas adsorption and melt adhesion, and further optimize the venting effect.
The outer shell structure should avoid sharp corners or sudden changes in local thickness to prevent heat concentration from causing deformation or cracking.
Traditional cold runners cause the melt to cool and solidify within the runner, leading to a decrease in pressure at the filling end and potentially causing uneven shrinkage.
