Injection Molding Surface Finishes
Enhance the appearance, texture, and functionality of your injection-molded parts with a wide range of finishing options.
As Molded
Description
Parts come directly from the mold without additional processing, showing the natural texture and gloss level defined by the tool steel and machining quality. Ideal for functional prototypes and cost-sensitive applications.
Advantages
- Most cost-effective finish
- Fastest lead time
- Consistent surface defined by mold quality
SPI Finished
Description
A standardized mold polish system (A1–D3) that defines different gloss levels, from optical-grade high polish to controlled matte textures—ensuring predictable appearance and mold consistency.
Advantages
- Industry-standard classifications
- Reliable surface repeatability
- Supports glossy, semi-gloss, and matte finish needs
Polishing
Description
Mechanical polishing enhances smoothness and visual clarity while reducing surface defects, weld lines, and minor imperfections. Ideal for aesthetic products and parts requiring better transparency.
Advantages
- Higher surface shine
- Removes minor tool marks
- Improves part cleanliness
Silk Screening
Description
A printing technique that applies logos, icons, labels, and patterns onto molded parts using mesh-based ink transfer, suitable for branding and durable graphic applications.
Advantages
- Customizable colors and patterns
- Affordable for medium–high volumes
- Strong adhesion for most plastics
Pad Printing
Description
A flexible printing method using a silicone pad to transfer fine graphics onto complex shapes, enabling detailed logos, symbols, and text on small or curved parts.
Advantages
- High detail accuracy
- Suitable for uneven/curved surfaces

- No inks or chemicals needed
Injection Molding Design Guidelines
Follow proven design principles to ensure manufacturability, reduce defects, and optimize cost, quality, and part performance in injection molding projects.
Features
Description
Wall Thickness
Maintain uniform wall thickness to prevent warping, sink marks, and uneven cooling. Typical range for common thermoplastics like ABS/PC is 1–3 mm, though this varies based on part size and material properties. Optimized thickness improves structural integrity and reduces material waste.
Draft Angle
Apply adequate draft angles (typically ≥1–2°) on vertical faces to ease part ejection and extend mold lifespan. Deeper draws or textured surfaces may require greater draft angles.
Ribs & Bosses
Reinforce parts with ribs and bosses without increasing wall thickness. Proper rib-to-wall ratios (typically 0.4–0.6× wall thickness) reduce stress and distortion while maintaining lightweight structures.
Corners
Use rounded corners (radius ≥ 0.5× wall thickness) instead of sharp edges to reduce stress concentration, improve material flow, and minimize sink marks or cracking.
Undercuts
Minimize undercuts where possible, or implement side-actions/sliders for complex geometries. Reducing undercuts simplifies mold design, decreases cycle time, and maintains dimensional accuracy.
Tolerance
Set realistic tolerances based on material properties and process capabilities. Typical achievable tolerances for precision injection molding:
±0.05 mm for critical features
±0.1 mm for general features

Injection Molding FAQs
Plastic pellets are melted, injected into a steel mold under high pressure, cooled, and then ejected as a solid part. The cycle repeats quickly, enabling fast, consistent, and cost-efficient mass production.
China offers competitive pricing, faster tooling lead times, mature supply chains, and extensive engineering expertise. Custom injection molding manufacturers like Livepoint combine high-precision tooling, automated production, and strict QC to ensure global-standard quality.
Costs depend on part complexity, mold design, materials, surface finish, and production volume. Simple molds may start at a few thousand dollars, while complex, multi-cavity tools cost more. Per-unit costs decrease significantly with higher volume.
Custom injection molding offers a powerful combination of high precision, material versatility, and cost efficiency for medium- to high-volume production. It can create complex geometries with consistent quality and supports a wide range of engineering plastics tailored to mechanical, thermal, or aesthetic requirements.
However, the process also comes with certain limitations. The upfront investment in mold fabrication can be substantial, and design changes after tooling is made may lead to additional cost and delays. Production is highly efficient once the mold is finalized, but it is less flexible for very low-volume or rapidly changing designs.
Despite these challenges, custom injection molding remains one of the most reliable and scalable manufacturing solutions for durable, repeatable plastic parts.
Yes. Once your mold is built, you can reorder at any time with no additional tooling cost, unless design changes are required or normal wear requires refurbishment.
No. Livepoint offers free mold storage for our customers. Your molds remain securely maintained and ready for repeat production whenever you need them.
