OEM High Precision CNC Aluminum Prototype Mould
This product is a set of fully CNC machined aluminum mould inserts,
used for rapid prototype injection moulding of handheld tool grip
plastic parts. Aluminum moulds feature ultra-fast processing
cycles, low cost and short lead time, ideal for small-batch trial
production, product verification and pre-mass sampling.
Product Overview
The picture shows multiple finished aluminum cavity plates with
symmetrical ergonomic grip cavities. Each plate contains two
identical handle-shaped forming cavities, machined via high-speed
CNC milling. Aluminum moulds are widely adopted for new product
validation before steel mould mass production, supporting small
volume trial runs of PP, ABS, TPE and other common plastics.
Core Technical Features
✅ Lightweight Aluminum Alloy Material Advantage
Material: 6061 / 7075 aerospace grade aluminum alloy
Low density, fast heat conduction, cooling efficiency 2–3 times
higher than steel moulds, greatly shorten injection cycle
Easy CNC machining, lead time cut by 40% compared to steel mould
Service life: 1,000 ~ 10,000 shots, perfect for prototype,
pre-production sampling, small batch orders
✅ High-Speed CNC Precision Machining
3-axis / 5-axis high-speed CNC milling for complex curved ergonomic
handle contours
Surface roughness Ra ≤0.8μm after fine milling, can be further
polished or textured
Dimensional tolerance controlled within ±0.02mm, meet prototype
assembly verification requirements
Integrated positioning pin holes, cooling channel holes and locking
notches one-time machining
✅ Independent Conformal Cooling Circuit
Built-in water cooling channels inside each aluminum plate, closely
surrounding the grip cavity to stabilize melt temperature,
effectively avoid warpage, sink marks and shrinkage defects on
curved handle parts.
✅ Flexible Mould Application
Single cavity / double cavity layout customizable based on customer
sample demand
Compatible with small to medium horizontal injection machines
(80T–200T)
Support single material injection or simple overmold prototype
testing
