PlasticNavi follows mold projects from the approved product design through mold design, manufacturing, trials, corrections and customer sample approval. Our mold design director has more than 20 years of mold-industry experience, and the mold design engineers each have more than 10 years of experience. Their practical knowledge of mold construction, injection molding, resin behavior, steel and component standards helps keep design decisions connected with the way the mold will actually be manufactured, tested and used. Our mold design engineers understand the injection molding process and, while maintaining the required part quality, consider how the mold design can reduce molding cycle time and control injection molding costs.
Before mold design begins, product, mold and tooling engineers review the latest approved part data, resin, expected production quantity, cosmetic surfaces, critical dimensions and customer mold requirements. DFM confirms draft, wall thickness, shut-offs and other risks, together with the proposed positions and shapes of parting lines, gates and ejector-pin marks. Mold-flow analysis can be used when required to study filling, cooling, deformation and related molding concerns.
Mold designers develop the tool around the approved product, production conditions and agreed mold standard. The team understands mold manufacturing, injection molding, resin behavior, mold steel and component standards including HASCO, DME and MISUMI. AutoCAD, Pro/E, SolidWorks and UG support the engineering work, and the customer reviews the mold design before manufacturing begins.
After mold-design approval, the tooling engineer prepares a manufacturing timetable and follows every manufacturing stage against the agreed milestones. Weekly updates include current progress, completed operations, the next planned steps and the latest available machining photographs, allowing customers to compare the schedule with actual tooling progress.
Each mold trial is evaluated against the approved product requirements. The team records molding conditions and reviews sample appearance, dimensions, assembly fit and functional results. Issues are converted into clear correction actions, followed through during mold adjustment, and verified in the next trial until the samples meet the agreed requirements and are ready for customer approval.
Mold Flow Analysis when required → Mold Design → Customer Mold Design Approval → Tooling Timetable → Mold Manufacturing → Weekly Progress Updates and Actual Machining Photos → Mold Trial → Sample Analysis and Measurement Reports → Correction or Additional Trial when required → Customer Sample Approval.
This sequence gives customers a clear view of the tooling route, while the detailed material, measurement, workforce and release controls are covered in the Quality Standards above.
PlasticNavi’s dedicated tooling factory is equipped for the complete mold-making process. Facilities include high-speed and medium-speed CNC machines, EDM, wire-cutting, grinding, drilling, lathes, milling machines and the supporting equipment required for mold manufacturing. High-precision inspection equipment and defined measurement procedures are used to verify steel components, dimensions and tooling work during production.
Dedicated molding machines are reserved for mold trials, supported by experienced mold-testing technicians and inspection personnel. Bringing mold manufacturing, measurement, trial molding and correction work into one coordinated workflow improves response time, supports consistent technical follow-up and helps us offer competitive mold pricing.

Quality controls are applied throughout mold planning, material purchasing, machining, trial molding, measurement and final release. The following standards help PlasticNavi maintain reliable tooling and consistent project follow-up.
Before a mold project begins, experienced engineers hold a project meeting to review and discuss each mold system, identify technical risks and consider the long-term reliability of the completed tool.
Mold steel and mold bases are purchased from established suppliers such as LKM and MINGLEE, with material certificates available to verify quality. For mass production, original plastic resin is purchased from the original manufacturers, official distributors or customer-approved suppliers.
Steel heat treatment is carried out by a qualified supplier from a recognized steel company, according to the requirements of the selected mold steel and tooling application.
Steel components are measured after each relevant machining process so dimensions, precision and machining accuracy can be checked before the next manufacturing stage.
Workers receive comprehensive training for their assigned mold-manufacturing operations, supporting consistent attention to detail throughout machining, fitting, assembly and related tooling work.
After mold testing, the project team meets to review the molding conditions, sample results and any issues found during the trial. Engineering, tooling, molding and quality personnel then discuss the required corrections and follow-up actions together.
After mold testing, part samples are measured against the supplied product drawings. Results are recorded in a detailed measurement report for review and project follow-up.
Before a mold is packed, every insert is inspected to confirm condition, fit and quality. Finished plastic products also follow defined inspection procedures covering appearance, dimensions, assembly and functional performance according to the project requirements.
These standards support PlasticNavi’s commitment to reliable molds, consistent production quality and customer satisfaction.
