Wall Thickness Guidelines For Injection Molded Parts

Aug 16, 2019·Wall thickness is ultimately dependent on the material you choose. The chart below outlines some general material thickness guidelines. MATERIAL. UNIT (INCHES) ABS. 0.045 - 0.140. Acetal. 0.030 - 0.120. Acrylic.

Wall Thickness - Minnesota Rubber & Plastics

Non-uniform wall thickness causes dimensional control problems, warpage and other part integrity issues. Production techniques on thin walls become quite complicated. For efficient, high volume production, we recommend a minimum wall thickness of 0.025 – 0.030 (0.635 – 0.762mm) on small parts, 0.040 – 0.050 (1.02 – 1.27mm) on larger parts.

Wall Thickness Design of plastic injection molded products

Commonly adopted wall thickness of various plastics. It is recommended that general plastic products adopt a wall thickness of 1-6mm, and the maximum can reach up to 8mm. The most commonly adopted wall thickness is 1.8-3mm, which is dependent on the type and size of the plastic part. Table 2 shows the parameters of commonly used wall ...

How Does Uniform Wall Thickness Improve Part Design?

Jun 14, 2018·By maintaining a uniform wall thickness, the part will cool as uniformly as possible. Injection molding is a pressure-driven process, and the molten polymer will take the path of least resistance. When there is variation in wall thickness, molten polymers take preferential flow to the thicker walls. This leads to air trapping, formation of weld ...
