28th September 2026

Custom PP + TPE grip parts are important to the comfort and performance of a hand gripper. The PP base provides strength and assembly support, while the TPE surface improves friction, touch and non-slip handling.

PP and TPE hand gripper parts shown with precision injection mold — PP structure and TPE overmolding need to be designed as one system.

Design and Tooling Review

The PP base, TPE edge, bonding area, ribs, texture, wall thickness and visible surface should be reviewed before mold construction. A stable mold plan helps reduce flash, sink marks, poor fit and inconsistent grip feel.

Custom molded PP and TPE grip tightener parts with injection mold — Custom molded grip parts require balanced material flow and clean edge control.

Injection Molding Quality Checks

Key checks include TPE edge quality, bonding area, surface texture, parting line, flash, color consistency and fit with the matching assembly. Maifeng Precision supports mold design, mold manufacturing and precision injection molding for PP + TPE grip parts.
