Precisión Lewei ______
Herramientas para un rendimiento óptimo
Lewei Precision applies strict tooling tolerances and quality standards to support reliable injection molding services across prototyping and production. Typical tooling tolerances are planned based on part geometry, material behavior, and mold class, with tighter control applied to critical features that affect fit, function, or assembly. Non-critical dimensions are managed with practical tolerance ranges to balance performance, manufacturability, and cost efficiency.
To ensure dimensional accuracy, all tooling and molded parts are verified using calibrated inspection equipment, including CMMs, height gauges, and pin gauges, depending on feature requirements. Where required, we provide First Article Inspection (FAI), detailed dimensional reports, and material certifications to confirm compliance before production release. This structured approach ensures consistent quality, repeatability, and confidence in every injection molding project.

Preguntas frecuentes sobre el mecanizado CNC
How much do injection mold tooling services cost?
The cost of injection mold tooling services depends on part complexity, mold size, tooling material, number of cavities, and required surface finish. Prototype tooling is typically more affordable, while production tooling costs more due to durability and longer tool life.
What affects injection mold tooling lead time?
Lead time is influenced by mold complexity, cavity count, tooling material, surface finish requirements, and the level of validation needed. Early DFM feedback and clear requirements help reduce tooling lead time.
Which tooling material is better: aluminum or steel?
Aluminum tooling is ideal for prototypes and low-volume injection molding services due to faster machining and lower cost. Steel tooling is better for high-volume production, offering higher durability and longer service life.
Can you match a specific surface finish or texture?
Yes, injection mold tooling can be finished with polished, matte, textured, or functional surfaces to meet cosmetic and performance requirements for injection molding services.
What files are required to quote injection mold tooling?
We typically require 3D CAD files such as STEP or IGES, along with material selection, quantity targets, and surface finish requirements to provide an accurate tooling quote.
Do you provide DFM feedback before tool manufacturing?
Yes, we provide DFM (Design for Manufacturability) feedback to optimize part geometry, reduce tooling risk, and ensure smooth injection molding production before cutting the tool.
How is the injection mold validated before production?
Mold validation includes pre-production inspection, T1 sampling, dimensional checks, and corrective adjustments to ensure the tool performs reliably in injection molding services.
Can low-volume tooling be scaled to mass production later?
Yes, tooling strategies can be planned to support low-volume production first and later transition smoothly to production tooling without changing suppliers.
What tolerances can you achieve for injection molded parts?
Typical molded part tolerances depend on part geometry and material, with tighter tolerances applied to critical features. Final tolerances are confirmed during tooling review and validation.
Do you offer tool maintenance or replacement inserts?
Yes, we support tooling maintenance, repairs, and replacement inserts to extend mold life and maintain consistent quality throughout injection molding production.
