Request an injection molding, overmolding or stamping quote
Submit your 3D CAD models and 2D engineering drawings for a direct technical review and quotation. Our European coordination desk in Cagliari and toolmakers in Ninghai evaluate tooling layout, resin options, cycle parameters, and delivery terms, issuing structured quotations covering mold investment and unit pricing within one to two European business days.
Submit drawing package and project parameters
Upload 3D CAD files (STEP) and 2D engineering drawings (PDF). Our engineering team reviews geometry for tooling feasibility and delivers complete pricing.
RFQ technical submission checklist for engineering buyers
Ensure your drawing package includes these parameters to expedite tooling analysis and quotation turnaround.
| Project parameter | Preferred engineering format | Why this information matters to the toolroom |
|---|---|---|
| 3D CAD geometry | STEP (.stp) or IGES (.igs) format | Allows direct volume calculation, parting line analysis, and draft verification |
| 2D engineering prints | PDF or DWG format with title block | Indicates critical fit tolerances, thread callouts, datum surfaces, and inspection notes |
| Polymer or metal alloy | Specific trade name or generic callout (e.g., ABS, PC, SUS304) | Determines tool shrinkage percentage, gate sizing, and cooling channel layouts |
| Annual & batch volume | Estimated initial run and annual forecast | Determines optimal mold cavity count (single cavity vs multi-cavity tooling) |
| Cosmetic surface finish | SPI polish class, VDI texture, or mold-tech specification | Sets toolroom polishing hours, bench labor, and required draft angle clearance |
| Regulatory documentation | RoHS, REACH SVHC, or food contact declaration | Ensures raw resin supplier certificates and batch traceability reports are scheduled |
| Delivery terms & port | FOB Ningbo, CIF destination, or DAP European facility | Allows precise international ocean freight and customs brokerage calculation |
What happens next: Our four step quotation evaluation flow
Step 1 Technical receipt: Your CAD files and drawings are reviewed under non disclosure terms by our European liaison desk in Cagliari to verify geometry completeness and tolerance annotations.
Step 2 Toolroom DFM review: Toolmakers in Ninghai evaluate mold filling, parting line locations, draft angles, gate options, and potential sink marks.
Step 3 Commercial quotation: We issue a formal written proposal detailing tooling cost, lead time to T1 samples, part unit prices across volume tiers, and delivery terms.
Step 4 Sample validation: Upon tooling completion, first article inspection reports and physical samples are delivered to your facility for sign-off before batch production starts.
Non disclosure agreements and CAD confidentiality
We treat proprietary product designs with strict professional confidentiality. We routinely sign bilateral Non Disclosure Agreements (NDAs) prior to receiving proprietary 3D CAD models.
CAD models and customer prints are stored on secure access-controlled servers and are utilized exclusively by our engineering team for tooling estimation and production purposes.
Direct coordination in European business hours
Inquiries from European engineering and procurement teams are managed directly by Isurus Works Studio in Cagliari, Italy.
This direct European channel ensures that technical discussions, design modifications, and commercial terms are addressed smoothly during European working hours, eliminating time zone friction and communication misunderstandings.

Frequently asked questions
Direct technical answers on processes, tooling, standards and commercial terms.
What 3D CAD file formats are accepted for technical review?
We accept STEP (.step or .stp), IGES (.igs), and Parasolid (.x_t) files for 3D modeling, accompanied by PDF or DWG engineering drawings for 2D tolerances and specifications.
Will Ningbo Haiming Electronics sign a Non Disclosure Agreement (NDA)?
Yes. We routinely execute bilateral non disclosure agreements before reviewing customer proprietary drawings, ensuring strict intellectual property protection.
How quickly will I receive an engineering evaluation and quotation?
Standard inquiries with complete 3D CAD files and specified order volumes receive initial engineering review and pricing within one to two European business days.
Can we inspect physical trial samples before committing to full batch production?
Yes. Physical T1 samples and full first article dimensional inspection reports are produced and delivered for customer evaluation and approval prior to production release.
What commercial payment terms apply to tooling and piece part orders?
Standard tooling terms involve a deposit to begin mold machining with balance upon sample approval. Production part runs are invoiced on standard commercial export terms.
