Cavity Mold: China-Based Plastic Injection Mold Manufacturer
Cavity Mold is a China-based plastic injection mold manufacturer in Shenzhen, Guangdong, supporting product designers, mechanical engineers, sourcing managers, OEMs, and procurement teams. We build custom injection molds and production tooling for plastic parts, with practical engineering support from the first design review through T1 trials and production follow-up.
Our main customer benefit is a clearer path from part concept to usable tooling. With more than 15 years of mold-making experience, we review manufacturability early, communicate the key decisions, and focus on molds that are ready for real production requirements.
Engineering, Machining and Mold Assembly
Company Overview
Cavity Mold is a China-based plastic injection mold manufacturer in Shenzhen, Guangdong. The company supports product designers, mechanical engineers, sourcing managers, OEMs, and procurement teams with custom injection molds and practical engineering support for production tooling.
With more than 15 years of mold-making experience, the team works from quotation and design review through mold manufacturing, T1 trials, modifications, and production follow-up. The focus is production-ready tooling, clear communication, and engineering decisions that help customers manage mold cost, lead time, quality, and maintenance.
Engineering and manufacturing capabilities
Good tooling starts before steel is cut. Our engineers review the part geometry, plastic resin, expected volume, critical tolerances, appearance requirements, and target schedule so that manufacturability risks are visible before mold construction begins.
- DFM and mold design: parting lines, draft, wall thickness, gates, cooling, ejection, sliders, inserts, maintenance access, and critical tolerances are considered during the design review.
- CNC and EDM machining: CNC milling and wire or probe EDM are used to produce mold components and detailed features for accurate fitting.
- Mold assembly and fitting: cores, cavities, inserts, sliders, and ejector systems are assembled and checked for alignment, movement, and maintainability.
- T1 trials and sample evaluation: initial samples are reviewed for filling, cooling, dimensions, appearance, fit, and function. When a change is needed, the tooling can be modified and the relevant checks repeated.
For projects that include part production, our injection molding support can help connect the tooling decision with the requirements of the finished plastic part. The exact scope depends on the part design, resin, tolerances, and production plan.
Clear milestones and approval points make responsibilities easier to follow for customers working from Europe, North America, or other international locations. We keep the engineering discussion connected to the commercial requirements, schedule, and next action.
Quality and Technical Control
Cavity Mold describes its factory as ISO 9001 registered as part of its quality-management and continuous-improvement program. For a current certificate, scope, or supplier-approval requirement, customers should request the applicable documentation during the quotation process.
- Material and component control: steel selection is matched to the required mold life, plastic material, part requirements, and customer specification. The company FAQ states that steel and heat-treatment certificates can be supplied with molds when required.
- Inspection and approval points: engineering reviews, 3D mold-design approval, T1 sample review, and modification checks provide visible points for customer feedback.
- Technical checks: dimensional, appearance, fit, and functional requirements are considered against the approved part information. Filling and cooling observations from the first trial help guide any necessary tooling changes.
- Project documentation: drawings, requirements, sample feedback, and agreed changes should remain aligned throughout the tooling process so that the final mold reflects the approved scope.

How to start a mold project
Send the information available for your project so the engineering team can review the requirements accurately:
- 3D CAD files such as STEP, IGES/IGS, or XT
- 2D drawings and critical dimensions or tolerances
- Plastic resin, grade, color, and any material specification
- Expected annual volume or planned production quantity
- Surface-finish, texture, appearance, fit, and functional requirements
- Target schedule, launch date, or other timing constraints
More complete information makes it easier to discuss mold construction, likely risks, and the next step. If some details are not final, send the current design and explain what is still under review.
