From mold base processing to trial molding and sampling, the timeline is not fixed and typically ranges from 2 to 6 weeks, depending on the complexity, size, structure of the mold, customer requirements, and factory scheduling. Below is a reference for the main stages:
- Mold Base Processing and Material Preparation: After receiving the design drawings, standard mold bases or customized rough mold bases are purchased and undergo rough machining (e.g., milling, drilling). This stage usually takes about 3-7 days.
- CNC Precision Machining: Involves fine milling, EDM (electrical discharge machining), wire cutting, etc., for core components such as cavities, cores, sliders, and lifters. For medium complexity, this typically takes about 1-2 weeks.
- Mold Assembly and Polishing: All machined parts are assembled, the mold is closed, and the cavity surfaces are polished. This stage generally requires 3-5 days.
- Trial Molding and Debugging: The mold is mounted on an injection molding machine for the first trial shot. It is repeatedly debugged based on issues with sample dimensions, appearance, and structure until standards are met. This stage has the most variability: simple molds may be completed in 2-3 days, while complex molds may require 1-3 weeks or even longer.
In summary:
- Simple molds (simple structure, fewer cavities): The entire process may be completed within 2-3 weeks.
- Medium-complexity molds (with sliders, lifters, etc.): The entire process takes approximately 3-5 weeks.
- High-complexity molds (multi-cavity, high precision, special materials): The entire process may exceed 6 weeks.
Key influencing factors:
- Design Maturity: Frequent design changes can significantly extend the timeline.
- Part Machining Difficulty: Deep cavities, thin walls, and micro-structures increase machining and polishing time.
- Supply Chain and Production Scheduling: Timely supply of materials/standard parts and factory order backlog.
- Number of Trial Iterations: More issues with the samples lead to longer debugging time.
For a more accurate delivery estimate, please provide the specific 3D mold drawings, technical requirements (material, number of cavities, lifespan, etc.), and sample acceptance criteria for evaluation.
