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 |

Surface Finishing Options
We offer high-quality injection molding services to produce precise, durable, and cost-effective parts.
-
Sandblasting
High-speed sand particles clean metal surfaces, removing oxides and dirt, creating a uniform texture.
-
Anodizing
Electrochemical reaction forms a hard oxide layer, improving aluminum's corrosion resistance and appearance.
-
Electroplating
Metal ions are deposited onto surfaces using electric current, enhancing corrosion resistance, hardness, and gloss.
-
Powder Coating
Electrostatic powder coating enhances weather resistance, scratch resistance, and provides uniform coverage.
-
Painting
Paint layers enhance appearance and protection, suitable for various colors and weather resistance needs.
-
Chroming
Chromium plating on metal surfaces improves corrosion resistance and gloss, commonly used for decorative parts.
-
Polishing
Mechanical or chemical treatment smooths and shines the surface, enhancing aesthetics and gloss.
-
Chemical Plating
Chemical reactions deposit metal layers on the surface, providing uniform coating and enhanced corrosion resistance.
-
Electropolishing
Electric current dissolves surface metal, removing burrs and improving smoothness, commonly used for stainless steel.
