3. Machining and Fabrication
Machining represents one of the most critical stages in the mould making process. Modern mould manufacturers in China employ highly advanced CNC machining centers, laser cutting machines, and ultra-precision milling tools. During this phase, the rough raw materials are transformed into components that will eventually form the mould.
Key aspects of this stage include:
- Rough Machining: This initial machining phase removes excess material and brings the workpiece closer to the desired shape. It uses high-speed cutting tools and often takes place on multi-axis CNC machines.
- Precision Machining: After rough machining, the workpiece moves into precision machining, where finer details and higher tolerances are achieved. This may involve micro-milling, grinding, or EDM (Electrical Discharge Machining). The precision of these operations is critical to ensuring that the mould will produce parts with the required dimensional accuracy and surface finish.
- Post-Machining Treatments: In many cases, additional treatments are required after machining. Processes such as polishing, surface hardening, or even cryogenic treatment can improve the mould’s wear resistance and longevity.
Advanced metrology tools, including coordinate measuring machines (CMM) and laser scanning systems, are used throughout this stage to verify that every dimension meets the design specifications. Rigorous quality control is applied at every step to ensure that the mould making process is not only efficient but also reproducible and compliant with international standards.
4. Assembly and Testing
In complex moulds that consist of multiple components, assembly is a critical part of the process. During this stage, all the machined parts are brought together to form the final mould assembly. Components such as sliders, ejector pins, and cooling channels are integrated and precisely aligned to ensure optimal performance.
The assembly process involves:
- Sub-assembly Integration: In cases where the mould consists of several sub-assemblies (for example, core and cavity parts), each sub-assembly is first tested individually and then integrated into the final assembly.
- Function Testing: Once assembled, the mould is tested for proper functionality. This may involve trial injections (if the mould is for plastic parts) or running sample material through the mould to assess quality. The purpose here is to verify all components are working in tandem and to identify any issues such as misalignment, improper clearances, or other defects.
- Iterative Improvements: Feedback from testing is used to optimize the mould. If any defects or variances are detected, the manufacturer may perform minor adjustments or rework portions of the mould to achieve the desired performance.
This stage is critical because it bridges the gap between theoretical design and real-world performance. By conducting thorough testing, the mould makers can be confident that the final product will meet customer expectations and operational requirements.
5. Finishing and Surface Treatment
