Process Related
We offer parallel processing where design optimization and tooling preparation happen simultaneously. Our rapid prototyping services using CNC and 3D printing can validate designs early, reducing iterations. Clear communication and prompt feedback from your team also significantly speeds up the process.
We have a structured change management process. Minor adjustments can often be accommodated during tooling phase. Major changes require impact assessment including timeline and cost implications. We always provide transparent communication about feasibility and alternatives.
We need your CAD files (STEP/IGES preferred), material requirements, quantity expectations, quality standards, and any specific functional requirements. The more detailed information you provide, the more accurate our initial assessment will be.
Yes, DFM analysis is a core part of our design phase. We review your design for manufacturability, suggest optimizations for cost reduction, quality improvement, and production efficiency. This helps prevent costly issues later in the process.
Time & Cost
Key factors include part complexity, mold cavity count, material selection, quality requirements, and design iterations. External factors like material availability and your approval timeline also impact delivery. We provide realistic timelines based on these variables.
Cost optimization strategies include design simplification, material selection, multi-cavity tooling for higher volumes, and eliminating unnecessary tight tolerances. Our DFM analysis identifies specific cost-saving opportunities for your project.
Standard injection molds typically take 4-8 weeks depending on complexity. Simple single-cavity molds may be completed in 4-5 weeks, while complex multi-cavity or family molds can take 6-8 weeks. We provide detailed timelines after design review.
Yes, we offer flexible payment terms for established clients and large projects. Typical structure is 50% down payment, 40% at first article approval, and 10% upon delivery. Terms can be customized based on project scope and client relationship.
Technical & Materials
We work with a wide range including ABS, PC, PA (Nylon), POM, PP, PE, TPU, and engineering grades like PEEK, PEI, and glass-filled variants. We also handle specialty materials for specific applications like food-grade, flame-retardant, and conductive plastics.
We offer texture finishing, polishing, painting, printing, plating, anodizing, and specialized coatings. Surface treatments can be applied to both molds (for molded-in textures) and finished parts. We help select the best option for your aesthetic and functional requirements.
We routinely achieve ±0.05mm for critical dimensions and ±0.02mm for precision applications. Tolerances depend on part geometry, material properties, and mold design. We discuss realistic tolerances during the design phase to balance quality and cost.

Yes, material selection consultation is part of our engineering support. We recommend materials based on your mechanical requirements, environmental factors, aesthetics, cost constraints, and regulatory compliance needs. Our experience with diverse applications helps guide optimal material choices.
