The Hexamold Quality Assurance Process

Hexamold applies documented quality controls throughout mold manufacturing, plastic production, assembly, and packaging. Each inspection plan is tailored to the product’s drawings, tolerances, materials, appearance standards, performance requirements, and destination market. For reference, ISO 9001 outlines internationally recognized principles for quality-management systems.

Before production begins, we review your CAD files, technical drawings, critical dimensions, cosmetic requirements, testing methods, and acceptance criteria. These specifications form a project-specific quality-control plan for consistent production and traceability.

Incoming resins, metals, colorants, and additives are checked against the approved material specifications and supplier documentation. Material identity, grade, color, and relevant certifications are verified before manufacturing.

Before volume production, Hexamold inspects initial samples against the approved drawings and CAD data. Depending on the project, the First Article Inspection report may include critical dimensions, appearance, material, assembly fit, and functional test results for customer approval.

During production, trained inspectors monitor critical dimensions, appearance, process stability, and functional requirements. Scheduled inspections help identify variation early and reduce the risk of defects affecting an entire batch.

Finished products undergo a final inspection before packaging and shipment. We verify agreed dimensional, cosmetic, functional, labeling, packaging, and carton requirements to ensure the order meets customer specifications and is ready for distribution.

Precision Mold Manufacturing

Hexamold designs and manufactures custom injection molds for consumer, packaging, automotive and industrial applications. With more than 30 years of experience, our toolroom integrates DFM, CAD/CAM, CNC machining, EDM, assembly, and mold trials.

Each mold is engineered around part geometry, resin, tolerances, surface finish, and production volume. Documented trials and dimensional inspection verify sample quality against agreed requirements before tooling release.

Custom Injection Molding

Hexamold provides custom injection molding for OEM and B2B customers, supporting projects from mold trials and pilot runs through repeat volume production. We process engineering thermoplastics and thermoplastic elastomers for complex, functional plastic components.

Controlled injection pressure, temperature, cooling, and cycle time help maintain dimensional accuracy, surface quality, and batch consistency. Integrated tooling and production support efficient manufacturing while reducing defects, material waste, and unit costs.

Custom Blow Molding

Hexamold manufactures hollow plastic products, including bottles, containers, reservoirs, and ducts, for packaging, automotive, consumer, and industrial applications. Our extrusion and injection blow molding services use resins selected for each product’s geometry and performance requirements.

Precision tooling and controlled processing help maintain wall thickness, dimensions, strength, and surface quality. Integrated mold manufacturing, inspection, assembly, and packaging support projects from design development through volume production.

Precision CNC Machining

Hexamold provides precision CNC machining for prototypes, mold components, production tooling, and low-volume end-use parts. Our capabilities include 3-, 4-, and 5-axis milling, alongside turning, for metals and engineering plastics.

Machining from customer CAD data, we support complex geometries, specified tolerances, and consistent surface finishes. DFM and dimensional inspection help verify component quality, whether CNC machining is a standalone service or preparation for molded production.

FDM 3D Printing and Rapid Prototyping

Hexamold provides FDM 3D printing and rapid prototyping using ABS, PC, TPU, and other engineering thermoplastics. We help engineering teams evaluate geometry, fit, assembly, ergonomics, and basic functionality before investing in production tooling.

Integrated DFM and prototyping help identify design risks and reduce avoidable tooling revisions. As projects develop, customers can transition to CNC machining, mold manufacturing, and injection molding through the same manufacturing partner.

Assembly, Labeling and Packaging

Hexamold provides contract assembly, labeling, kitting, and packaging to prepare products for retail, distribution, and international delivery. Options include product labels, barcodes, traceability markings, protective packaging, inserts, cartons, and custom-printed corrugated boxes.

Workflows follow customer requirements for protection, presentation, and cleanliness. Inspections check label accuracy, barcode readability, component quantities, and packaging integrity, while integrated manufacturing and packaging reduce supplier handoffs and simplify quality control.

Plastic Contract Manufacturing FAQs

Hexamold provides integrated services including DFM review, mold manufacturing, injection molding, blow molding, CNC machining, FDM 3D printing, quality inspection, assembly, labeling, packaging, and global delivery. We support OEMs, product companies, engineering teams, and procurement professionals from initial design through volume production.

For an accurate quotation, provide available 3D CAD files, 2D drawings or authorized samples, preferred material, dimensions, tolerances, surface requirements, expected order volume, packaging needs, and destination market. If some details are not finalized, Hexamold can identify the information needed during the project review.

Yes. Hexamold provides design-for-manufacturability review to identify potential issues with wall thickness, draft angles, undercuts, tolerances, material selection, parting lines, assembly, and tooling. Addressing these details before mold manufacturing can reduce tooling revisions, production defects, material waste, and overall project risk.

Yes. FDM 3D printing and CNC machining can be used to evaluate geometry, fit, assembly, and basic functionality before production tooling. After mold manufacturing, trial samples can be inspected and reviewed before the project advances to pilot runs or volume production.

Injection molding is generally used for solid plastic parts, housings, fittings, automotive components, and products with detailed features. Blow molding is designed for hollow products such as bottles, containers, reservoirs, and ducts. Hexamold evaluates the product geometry, material, performance requirements, and production volume before recommending a process.

Pricing and lead time depend on part size, geometry, tolerances, mold construction, cavity count, material, surface finish, production volume, inspection requirements, assembly, and packaging. Minimum order quantities also vary by process and product. Hexamold reviews these factors before providing a project-specific quotation and production schedule.

Quality planning is based on the customer’s drawings, tolerances, materials, appearance standards, functional requirements, and destination market. Depending on the project, controls may include incoming-material inspection, first-article inspection, in-process checks, dimensional verification, final inspection, and pre-shipment validation.

Yes. Hexamold can coordinate component assembly, labeling, kitting, protective packaging, retail packaging, cartons, inspection, and export preparation. From Zhangjiagang, Suzhou, China, we support international customers with finished products prepared according to their packaging, documentation, and global delivery requirements.
