Tolerances for Injection Molding
| Tolerance Level | Application | Tolerance Range |
| General Tolerances | Standard injection molded parts | ±0.1mm to ±0.5mm |
| High Precision | Tight tolerance for small or complex parts | ±0.05mm to ±0.1mm |
| Large Parts | Larger molded parts (e.g., automotive) | ±0.5mm to ±1.0mm |
| Thin-Walled Parts | Thin-walled products | ±0.1mm to ±0.3mm |
| Plastic Materials | Varies by material (e.g., ABS, Nylon) | ±0.1mm to ±0.3mm |

Injection Molding Surface Finish Options
Choose from molded textures, polished surfaces, coatings, printing, engraving, and decorative finishes to achieve the appearance, feel, branding, and functional requirements of your injection-molded plastic parts.
-
High-Gloss Polishing
Creates a smooth, reflective surface for consumer products, cosmetic housings, and appearance-focused plastic components.
-
Matte Surface Finish
Provides a low-glare appearance that helps reduce visible fingerprints and minor surface marks.
-
Mold Texture
Adds fine grain, leather-like patterns, or customized textures directly through the injection mold surface.
-
Custom Painting
Applies specified colors and protective coatings to achieve consistent appearance across molded components.
-
Silk Screen Printing
Suitable for applying symbols, operating instructions, graphics, and branding to flat or slightly curved surfaces.
-
Pad Printing
Transfers detailed graphics onto curved, recessed, or irregularly shaped injection-molded plastic parts.
-
Laser Engraving
Creates durable markings, symbols, identification details, or decorative patterns without using printed ink.
-
Soft-Touch Coating
Adds a smooth, comfortable tactile finish to handheld devices, control components, and premium product housings.
-
Vacuum Metallization
Produces a decorative metallic appearance on molded plastic components without changing the base material.
