Product Overview
This customized plastic mount bracket is a precision structural accessory widely used for equipment fixing, electronic assembly and mechanical connection. We develop matching custom injection mold for this bracket, supporting single cavity or multi-cavity mass production according to customer output demand.
The part features dual counterbore mounting holes for screw locking, rounded end contours and undercut notch structure at the bottom. Our mold design optimizes ejection and parting line layout to avoid flash, sink mark and deformation during injection molding.

Mold Design Highlights
✅ Undercut Optimization: Bottom recess adopts slide/lifter structure for smooth automatic demolding without secondary manual trimming.
✅ Balanced Filling: Optimized runner layout eliminates uneven shrinkage around two mounting holes, ensures concentric tolerance of inner bore.
✅ Durable Cavity: Hardened mold steel improves wear resistance, stable dimensional precision for long-term batch production.
Application Fields
Equipment fixed support, household appliance internal bracket, automotive small assembly, electronic module fixing base.
FAQ
Q1: Can we change cavity quantity of this bracket mold?
A1: Yes, we can design 1×1/1×2/1×4 cavity layout based on your monthly production volume to balance mold cost and production efficiency.
Q2: Which material is recommended for high-load usage?
A2: Glass-filled PA66 or POM is preferred for heavy load; ABS is for general indoor assembly.
Q3: Is bottom undercut need manual demolding?
A3: Our mold adopts built-in lifter mechanism to realize automatic ejection, no extra post-processing required.
