CNC Machining & Injection Molding — DFM/Moldflow Support, CMM Inspection, Prototype to Production Solutions.
We build production injection molds in China for transfer to customer-owned or contract molding facilities in the US, Europe, and other overseas markets. Before steel cut, we confirm mold standards, receiving-press interfaces, resin requirements, and CTQ features. Before shipment, we provide the agreed trial, inspection, and handover evidence needed for plant-side startup.
Recommended inputs: 3D/2D files · resin grade · annual volume · target press data · mold standard

Mold standards, press interfaces, trial evidence, inspection records, spare parts, and release documents are aligned before shipment.
An export mold is a production injection mold built and validated in China, then shipped to the customer’s own factory or designated contract molder for ongoing production. Unlike contract injection molding, the customer receives a production asset that must install, start, run, and remain serviceable at another facility.
SPI builds, trials, documents, protects, and ships the mold for production at your own plant or nominated molding facility.
SPI retains and operates the production mold, controls the molding process, and supplies approved finished plastic parts to your required delivery schedule.
The route becomes lower risk when the production requirements and receiving environment are confirmed before mold design approval.
Export tooling must be controlled as a transferable production asset, not only as a mold that produces acceptable samples in the supplier’s trial shop. Our process connects design review, mold manufacturing, T1/T2 validation, inspection evidence, and shipment release so the receiving plant has a clearer basis for installation and startup.
Project requirements are reviewed before the mold structure and manufacturing scope are released.
The mold structure is developed around the approved part geometry, production requirements, and customer plant interfaces.
Trial results are reviewed against the agreed sample, cosmetic, functional, and dimensional approval requirements.
The mold and its supporting records are prepared for transfer to the receiving factory or nominated molding facility.
| Mold standards | DME, HASCO, LKM, or customer-specified mold and component standards confirmed before design release. |
|---|---|
| Tooling structures | Production molds, single- or multi-cavity layouts, inserts, sliders, lifters, and hot- or cold-runner systems reviewed according to part geometry, resin, volume, and maintenance needs. |
| Plant compatibility | Locating ring, nozzle interface, mold height, tie-bar clearance, ejection, cooling, electrical, hydraulic, and hot-runner requirements aligned with the receiving press. |
| Inspection support | Dimensional inspection, CMM reports, FAI records, material or steel documentation, and PPAP-style support based on the agreed RFQ and approval scope. |
| Export handover | Trial evidence, approved design references, molding condition information, spare-parts visibility, packing records, and shipment documents prepared according to project requirements. |
An export mold must match the receiving press and plant standards, not only the plastic part drawing. Before mold base ordering and final design release, we align the machine envelope, injection and ejection interfaces, cooling, hot runner, auxiliary actions, handling, and maintenance requirements with the customer’s actual production site.
A mold can produce acceptable samples in the supplier’s trial shop and still create startup delays after shipment if the machine, utility, control, or maintenance interfaces were based on assumptions.
The following inputs should be confirmed before design freeze or steel release. The exact scope depends on the target press, mold structure, hot runner system, and receiving-plant maintenance standard.
| Interface group | What to confirm before release | Risk if missed |
|---|---|---|
| Mold standard | Mold base and component standard, approved brands, replacement components, drawing conventions, and spare-parts expectations. | Replacement parts and maintenance practices may not match the receiving plant. |
| Press fit and clamping | Mold width, height, thickness, weight, platen size, tie-bar spacing, mold-height range, clamp slots, and mounting method. | The mold may not load, fit, clamp, or operate safely on the selected press. |
| Injection and ejection | Locating ring, nozzle radius, sprue diameter, ejector pattern, KO layout, ejector stroke, return method, and required clearances. | Alignment, material transfer, ejection, or mechanical interference problems may delay startup. |
| Cooling connections | NPT, BSP, or metric threads, quick connectors, circuit identification, manifold layout, flow direction, and plant-side connection positions. | Waterline modification, connection errors, poor cooling, or additional setup work may be required. |
| Hot runner and electrical | Hot runner brand, voltage, zone count, wiring, connector type, controller compatibility, thermocouples, heaters, and sensors. | Electrical incompatibility or controller mismatch may prevent the hot runner from starting correctly. |
| Hydraulic and pneumatic actions | Connector type, pressure, stroke, sequence, limit switches, sensors, core-pull actions, and machine-control requirements. | Sliders, lifters, core pulls, or interlocked movements may not function safely. |
| Handling and maintenance | Lifting points, center of gravity, loading orientation, maintenance access, wear inserts, spare parts, vent cleaning, and hot runner service access. | Installation, preventive maintenance, repair, and component replacement may become slower or unsafe. |
You do not need a fully completed specification package to begin an engineering review. Five core inputs are usually enough for us to identify the likely tooling route, major design assumptions, missing plant-interface information, and the additional details needed for a more accurate quotation.
STEP, STP, X_T, IGS, or another usable CAD format for part geometry and mold-feasibility review.
PDF or DWG showing dimensions, tolerances, datums, CTQ features, surface notes, and drawing revision.
Exact resin grade where available, including filler, color, supplier, flame rating, or performance requirements.
Expected annual quantity, program life, prototype or production stage, and target launch or shipment timing.
Receiving press information and DME, HASCO, LKM, or other required mold standard, if already defined.
These details reduce commercial assumptions and help align mold structure, inspection scope, approval timing, and handover deliverables before the project starts.
Send the CAD file, drawing, resin, volume, and target mold standard first. Missing inputs can be identified during the initial engineering review before a formal tooling quotation is released.
Shipment approval should be based on the current mold condition and agreed release evidence—not only completion photos. Before dispatch, the customer should be able to verify that the mold matches the approved specification, the latest tool condition has been trialed and inspected, and the handover package can support installation, startup, and maintenance at the receiving plant.
Confirm that the mold structure, mold standard, approved design, and project-specific build requirements match the current tool.
Confirm that T1/T2 evidence, samples, correction records, and CTQ inspection results represent the latest mold condition.
Confirm that startup references, spare parts, protection, packing evidence, and required release records are complete before shipment approval.
The exact document scope is defined during the RFQ and approval process. Core handover records are supplied for the export program, while FAI, PPAP-style documents, steel certificates, and expanded validation records depend on the customer and industry requirements.
Final approved 2D/3D mold references, agreed mold standard, and relevant design-release information for maintenance and future changes.
Trial videos, sample status, molding conditions, visible mold movements, and correction records representing the current tool state.
Dimensional or CMM results for agreed fit, sealing, assembly, functional, cosmetic, and other release-critical features.
Steel-grade, insert-material, heat-treatment, and hardness evidence for specified core, cavity, and wear-sensitive areas.
Molding-condition references, waterline identification, spare-parts information, maintenance access notes, and relevant service records.
Rust prevention, shutoff-surface protection, secured moving actions, lifting information, crate condition, and pre-dispatch photographs.
Export mold cost and lead time depend on more than mold size or the number of machining hours. A reliable quotation should connect the tooling structure, expected mold life, receiving-plant standards, validation scope, correction allowance, and shipment-release work to the actual program requirements.
Undercuts, deep ribs, thin shutoffs, sliders, lifters, inserts, unscrewing actions, and difficult ejection increase design, manufacturing, fitting, and trial effort.
Cavity count, family layouts, hot or cold runner selection, valve gates, flow balance, and required automation affect mold cost, cycle expectations, and validation scope.
Resin wear, corrosion risk, expected production cycles, heat treatment, polish, texture, replaceable inserts, and maintenance access influence material and manufacturing decisions.
DME, HASCO, LKM, customer standards, target press interfaces, cooling connections, hot runner controls, sensors, and auxiliary actions must be included in the tool scope.
T1/T2 expectations, sample quantity, CTQ inspection, CMM or FAI records, cosmetic approval, PPAP-style requirements, and correction loops affect both cost and schedule.
Customer approval time, design changes, spare parts, startup references, rust prevention, packing, release documents, and shipment readiness must be reflected in the overall program plan.
Tool-build time should not be presented as one undivided number. The quotation should identify the schedule basis, customer approval points, assumed correction cycles, and whether packing and shipment release are included.
A lower tool price is not necessarily a lower total project cost. Compare whether each supplier has quoted the same technical, validation, and handover scope.
Anonymized Export Mold Program
This anonymized program summary shows how an automotive structural housing mold was prepared for transfer to a customer-designated production facility. Customer identity, part drawings, and confidential dimensional data are not shown, but the project stages and release responsibilities reflect the actual export-mold workflow.
The program required a production mold that could be installed and qualified at another molding facility after shipment. Before design release, the project team aligned the mold standard, receiving-press interface, resin assumptions, CTQ inspection scope, trial evidence, and handover requirements.
Mold-standard and machine-interface requirements were reviewed together with the part design, resin, CTQ features, inspection expectations, and planned release records.
T1/T2 evidence, sample condition, process information, corrective actions, and CTQ results were reviewed against the mold revision intended for shipment.
Approved design records, trial evidence, dimensional reports, molding conditions, spare-parts information, packing records, and handover documents were checked as one release package.
The mold was released against an agreed specification and a defined evidence package rather than a general “tool complete” confirmation. This gave the receiving team a clearer basis for installation, startup review, and follow-up after arrival.

Review Specification TemplateAnswers to common questions about export mold quotation inputs, international mold standards, receiving-press compatibility, trial evidence, inspection documents, lead time, and support after delivery.
We normally need the 3D CAD file, 2D drawing, resin grade, estimated annual volume, expected mold life, target launch date, CTQ dimensions, cosmetic requirements, receiving-press data, and preferred mold standard. Confirming these inputs before design approval reduces quotation assumptions and late tooling changes.
Yes. We can follow DME, HASCO, LKM, or a customer-defined mold standard when the required components, maintenance preferences, spare-parts strategy, and receiving-plant requirements are confirmed before mold design is released.
Before steel cut, we review the target press tonnage, platen size, tie-bar spacing, mold-height range, locating-ring diameter, nozzle radius, ejector stroke, clamping arrangement, cooling connections, and hot-runner interface where applicable. These requirements are recorded in the mold specification before final design approval.
The agreed release package can include T1/T2 trial videos, sample photographs, molding-condition records, corrective-action status, and CTQ or CMM dimensional results. The exact evidence scope is defined during quotation so shipment approval reflects the current mold condition and approved sample revision.
Depending on the project, the handover package may include approved 2D and 3D design files, mold specification, trial report, molding parameter sheet, CTQ or CMM report, steel and hardness records, spare-parts list, packing photographs, and shipment-release documents. FAI, PPAP, material certificates, and other quality documents should be specified in the RFQ when required.
Lead time depends on part complexity, mold size, cavity count, steel and component availability, hot-runner requirements, design approval time, trial and correction rounds, inspection scope, and shipment-release requirements. A project schedule is confirmed after the drawings, mold specification, and approval process have been reviewed.
We first review the receiving-press setup, molding parameters, installation condition, trial records, sample condition, and the reported issue to determine whether it is process-related, interface-related, or tool-related. Depending on the finding, support may include remote engineering review, replacement wear parts, adjustment guidance, or an agreed mold-correction plan.
