A Collapsible cores are commonly used for injection molded parts with internal undercuts, deep cavities, or complex internal features that require efficient demolding. Typical applications may include certain packaging closures, bottle-neck related parts, and functional plastic components. Final suitability depends on the actual part design and mold structure.

A High-precision machining is one of our core strengths. The achievable tolerance depends on the part geometry, material, heat treatment, surface finishing, and inspection requirements. Once we review your drawing and key dimensions, we can recommend a realistic tolerance range and quality control plan for your project.

A Yes. We support custom manufacturing based on 2D drawings, 3D models, or sample requirements. We can also review your application needs—such as demolding method, part geometry, cycle time, and material behavior—and suggest practical improvements to component structure and tolerances for production and maintenance.

A We specialize in high-precision mold components and custom machining services, including mold components, CNC machining parts, and collapsible cores. Based on your mold structure, product design, and production targets, we can also support custom tooling solutions for more reliable molding performance and easier maintenance.

A We focus on the mold components and CTQ features that most directly affect sealing, fitting, and repeatability, such as core pins, cavity inserts, neck rings, thread-related diameters, and sealing lands. Key dimensions are checked during production and reviewed again before shipment using methods such as CMM inspection and fit-related verification. This helps reduce cavity variation, improve sealing consistency, and lower the amount of fitting work needed during mold assembly and trial runs.


How do you control cavity-to-cavity consistency in a 24-cavity cap mold?

A

Yes. We support custom machining of collapsible core components for precision mold applications. These parts are often used in molds with internal undercuts, thread features, or complex inner structures where stable movement, fitting accuracy, and wear resistance are important. You can also visit our case study article to see how collapsible core components are used in actual mold projects.

A Yes, we can. We support custom manufacturing based on provided drawings or physical samples—including standard and non-standard mold components, precision CNC parts, collapsible core mechanisms, and more. Based on your specific industry application (e.g., packaging, medical, automotive), we conduct a comprehensive process evaluation regarding dimensional tolerances, concentricity, surface roughness, material specifications, and heat/surface treatment requirements to formulate an optimal manufacturing plan. Once your requirements are confirmed, we proceed with prototyping or small-batch production; full-scale mass production commences only after the samples have successfully passed inspection. You simply need to provide your 2D/3D design files (in formats such as STEP, IGES, DWG, etc.), material and hardness specifications, critical dimensions and tolerances, and details regarding the intended operating conditions.
