TigerHubs defines critical dimensions, appearance standards, material requirements and functional checks before production, helping customers receive consistent molded parts that meet drawing and assembly requirements.
Engineering Validation Before Production
We review wall thickness, draft angles, gates, cooling, shrinkage and critical dimensions before tooling. T1 samples are checked for dimensions, appearance, fit and function before the mold is approved for production.
Controlled and Traceable Molding
Approved resin grades, material batches and key molding parameters are controlled throughout production. Mold number, cavity number, production batch and inspection records remain traceable for repeat orders and issue investigation.
Inspection Based on Part Requirements
Critical dimensions, cosmetic surfaces and functional features are inspected against the approved drawing and master sample. Dimensional reports, CMM inspection, FAI, Cpk studies or PPAP documentation can be provided when specified for the project.

Frequently Asked Questions
Learn MoreInjection molding cost is mainly determined by tooling complexity, mold material, cavity count, part size, resin, surface finish, production volume and inspection requirements. The initial mold creates a higher upfront cost than processes such as CNC machining or 3D printing, but the unit cost normally decreases significantly as production volume increases. The most accurate way to estimate cost is to review the CAD model together with the expected lifetime production quantity.
The practical minimum depends on the tooling strategy and commercial requirements. Prototype injection molds can support very small validation runs, while production tooling becomes more economical as quantity increases. TigerHubs evaluates tooling cost and piece-part economics together instead of applying one fixed MOQ to every program.
Common materials include: ABS, PC, PC/ABS, PP, PE, HDPE, LDPE, PA, POM, PMMA, PBT, PET, TPU, TPE, PPS, PEEK and PEI. Additional grades can be evaluated based on strength, temperature, chemical resistance, appearance, electrical requirements and project-specific needs.
A common design reference is approximately 0.5–5.0 mm, depending on material and geometry. Uniform walls are generally preferred because large thickness changes can increase sink, warpage, cooling imbalance and cycle time.
A general starting range is approximately 0.5°–2.0° per side. Deep features, textured mold surfaces and certain materials may require greater draft. Final draft should be reviewed during DFM.
Low-volume injection molding can be used for pilot production, bridge manufacturing, product launches and demand validation before committing to long-life tooling or higher production volumes.
Yes. T1 sampling is a critical step in the TigerHubs tooling workflow. Initial molded parts can be reviewed for dimensions, appearance, mold filling, ejection, sink, warpage, flash, weld lines and functional requirements before repeat production begins.
Yes. DFM review can evaluate wall thickness, draft, undercuts, gates, parting lines, ejection, ribs, bosses, cosmetic areas and critical dimensions before tooling release. The objective is to identify manufacturing risks while they are still easier and less expensive to change.
Yes, multi-cavity and family-mold strategies can be evaluated when production requirements justify them. Cavity count depends on part geometry, annual volume, mold size, filling balance, required production rate and tooling budget.
Insert molding and overmolding can be evaluated for compatible part designs and material combinations. These processes can integrate threads, electrical components, reinforcing elements, grips, seals or other functions into the molded component.
