Polished Plastic Injection Mould For Precision Part Production
Details of Polished Plastic Injection Mould
High-Gloss Moulds Built for Dimensional Accuracy
With deep experience in the moulding industry, we offer a premium-grade range of Polished Plastic Injection Moulds designed to deliver smooth finishes and tight tolerances in plastic component manufacturing. These moulds are widely used in sectors requiring both functionality and surface appeal, such as automotive, electronics, medical, and consumer goods.
What Is a Polished Plastic Injection Mould?
A Polished Plastic Injection Mould is a custom-fabricated steel or alloy tool used in injection moulding machines to form plastic parts. The interior surfaces are polished to a high degree to ensure a flawless, glossy finish on the final product, reducing the need for post-processing.
Common Industries Using This Mould Type
These moulds are used in:
- Precision electronic enclosures and gadget housing
- Transparent parts like LED lenses and display covers
- Medical device casings and sterile-use plastic components
- Automotive interiors, knobs, panels, and trim pieces
- Packaging for cosmetics and personal care products
These products are used in industrial applications where both form and finish matter equally.
Key Engineering Features
- CNC-machined cavities with mirror-grade polish
- Mold base built from hardened P20, H13, or stainless steel
- Optional hot-runner systems for efficient material flow
- Venting channels to prevent burn marks or voids
- Tight shut-off lines for crisp edges and parting lines
7 Key Benefits of Polished Plastic Moulds
- Produces parts with smooth, glossy, or optically clear surfaces
- Reduces secondary operations like buffing or coating
- Enhances plastic flow and fill for complex geometries
- Increases mould lifespan with corrosion-resistant polish
- Delivers accurate replication of tiny design features
- Prevents dust or particulate adhesion to finished parts
- Ideal for transparent and high-clarity plastic materials
Material Compatibility and Finish Range
- Works with PC, PMMA, ABS, PP, and high-gloss polymers
- Surface finish options: SPI A1 to A3 (mirror-grade polishing)
- Compatible with multi-cavity and single-cavity formats
- Mould temperature control supports material-specific shrinkage
- Suitable for both horizontal and vertical injection machines
Why Polished Moulds Are Chosen for Premium Parts
These moulds are used in commercial and industrial applications that demand both functional accuracy and a refined finish. From transparent display panels to gloss-finished cosmetic cases, they deliver consistent, production-ready results without extra processing time.
Key Considerations Before Ordering
- Confirm surface finish standard required (SPI, VDI)
- Select a steel grade based on the expected volume
- Account for part geometry, gate location, and venting
- Ensure compatibility with injection pressure and resin type
