PEI plastic aluminum composite roller consists of two separately CNC machined raw parts: solid aluminum inner core and curved waist PEI plastic outer sleeve, after precision dimensional matching to complete tight assembly without adhesive filling. Independent CNC turning processing for each raw piece ensures the PEI plastic aluminum composite roller keeps stable concentricity during long-term rolling operation.
The aluminum core section of PEI plastic aluminum composite roller is made from premium solid aluminum bar via CNC turning and bore machining, the stepped structure of aluminum core provides reliable positioning and load bearing for outer plastic sleeve, improving the overall structural stability of PEI plastic aluminum composite roller under continuous rolling load.
The outer curved waist sleeve of PEI plastic aluminum composite roller adopts high-performance engineering PEI plastic raw material. PEI plastic endows PEI plastic aluminum composite roller with superior high temperature resistance, excellent self-lubricating property and great anti-abrasion performance. The special concave waist outline design of PEI plastic outer body effectively limits component offset during guiding movement.
This PEI plastic aluminum composite roller is extensively applied as guiding roller, conveying wheel and positioning roller in automation production lines, precision testing equipment and electronic assembly machinery. PEI plastic aluminum composite roller matches with fixed shaft components to complete smooth material guiding and transmission work.
Customization service for PEI plastic aluminum composite roller includes core diameter, outer roller size, waist radian modification, different engineering plastic material replacement and aluminum surface treatment options. Each finished PEI plastic aluminum composite roller undergoes concentricity and dimension inspection before delivery. With over 20 years of CNC custom machining experience, GRANDIND supplies qualified plastic and metal composite machined parts for worldwide buyers.
