Dependent on the part design and size, typically, for injection molded parts, the wall thickness will be in the range 0.5 mm to 4 mm (0.02 - 0.16 inch).
For parts made from most thermoplastics, nominal wall thickness should not exceed 4.0 mm. Walls thicker than 4.0 mm it is will increase time required for cooling and will result in increased cycle times
Changing the wall thickness of a component has a significant effect on the following key properties:
1.component weight
2.achievable of cycle time because more time 3.for cooling and injection
4.tolerances of product
5.achievable flow lengths in the mould
6.production cycle time of the component
7.rigidity of the moulded part
8.quality of the component in terms of surface finish, warpage and voids.
9. will affect to determines mechanical properties
What the Disadvantage when Thickness not Uniform
In the design of plastics components, it is important to aim for uniform wall thickness. Different wall thicknesses in the same component cause differential shrinkage which, depending on component rigidity, can lead to serious warpage and dimensional accuracy problems
what we should do when design a mold that have different thickness, look at the following picture, we should make as possible uniform or make the transition of product is gradual
Generally, the maximum wall thickness used should not exceed 4 mm. Thicker walls increase material consumption, more need time for cycle time considerably, and cause high internal stresses, sink marks and voids, look at picture below

Before purchasing sheets for industrial usage, price comparison plays a vital role. Customers often inquire about HDPE Sheet for Cable Reels price to evaluate cost-effectiveness along with quality. The price usually depends on thickness, size, and application-specific requirements. Many companies offer competitive rates without compromising on strength and flexibility. For industries handling cable drums and reels, finding the right balance between price and durability ensures better return on investment and long-term usage.
