Injection Molding Tolerances: What Is Achievable?

Injection molding tolerances vary by material, part geometry, and mold design. Standard commercial tolerances are typically ±0.1mm, while precision tolerances can reach ±0.01mm or better. Factors affecting tolerances include: material shrinkage rate, mold temperature control, injection pressure consistency, and mold wear over time. Yinzan Technology holds tight tolerances through precision machining, scientific molding practices, and rigorous CMM inspection. Our typical capability is ±0.01mm on critical dimensions and ±0.05mm on general dimensions.
