Phase 1: Requirements Analysis and Design - The Cornerstone of Success

This is the starting point of the project, aiming to "do it right the first time."

In-depth Requirements Communication:

Functional Requirements: Part's operating environment, load, temperature resistance, chemical resistance, flame retardancy rating (e.g., UL94 V-0).

Appearance Requirements: Surface treatment (high gloss, matte, textured, spray painting, electroplating), color (provide Pantone color code).

Precision and Regulations: Dimensional tolerances (comply with GD&T standards), assembly requirements, industry certifications (e.g., FDA, RoHS).

Budget and Timeline: Target cost, project timeline, expected output.

Product Design Optimization and DFM (Design for Manufacturability Analysis):

Core Value Element: Close collaboration between the mold supplier and your design team.

Analysis Content:

Wall Thickness Uniformity: Recommended 2.5-3.0mm to avoid shrinkage and warping.

Draft Angle: Ensure smooth demolding, typically ≥1°.

Reinforcing Ribs and Screw Studs: Rationally designed (rib thickness ≤ 60% of main body wall thickness) to prevent back shrinkage.

Rounded Corner Transitions: Avoid stress concentration and improve plastic flow.

Parting Line Determination: Select the location with minimal impact on aesthetics and function.

Gate Location and Type: Evaluate the optimal gate point, balance filling, and reduce weld lines.

Output: Professional DFM report providing detailed optimization suggestions and confirmation with you.

Material Selection:

ABS Basic Characteristics: High strength, good toughness, easy to process, easy to dye, and easy to surface treat.

Grade Selection:

General Purpose Grade: Most commonly used.

High Impact Grade: Used for parts requiring higher toughness.

Heat Resistant Grade: Used for parts operating in high-temperature environments.

Electroplated Grade: Specifically for applications requiring electroplating.

Second Stage: Mold Design and Manufacturing - The Birth of Precision Tools

The mold is the "mother" of the product; its quality directly determines the quality of the parts.

Mold Design:

Mold Flow Analysis: A standard feature of modern precision injection molding. Computer simulations of plastic filling, cooling, shrinkage, and warpage predict and resolve issues such as air pockets, weld lines, and shrinkage, optimizing the gating and cooling systems.

Structural Design: Design of the mold base, cavities/cores, slides/ejectors (for undercuts), cooling channels, and venting systems.

Precision Machining and Assembly:

Machining Processes: Machining of mold cores and inserts using CNC (Computer Numerical Control), EDM (Electrical Discharge Machining), and wire cutting processes.

Surface Treatment: Specific treatments for the cavities, such as mirror polishing (for high-gloss surfaces) and VDI texturing (e.g., leather texture).

Mold Assembly (Fitting): Precision assembly and adjustment of all parts by a senior fitter to ensure smooth and error-free movement of all components.

Third Stage: Mold Trial and Process Optimization - Verification and Fine-tuning

This is the crucial bridge connecting the mold to mass production.

Initial Trial Molding (T0): Install the mold on the injection molding machine, perform preliminary adjustments using production materials, and produce the first batch of samples.

ABS-Specific Process Adjustment Points:

Material Drying: ABS must be dried at 80-85℃ for 2-4 hours to prevent silver streaks on the product surface.

Mold Temperature: Use a relatively high mold temperature of 60-80℃. High mold temperature is key to obtaining a high-gloss surface, reducing weld lines, and lowering internal stress.

Injection Speed: Medium to high speed injection is generally used to obtain a glossy surface.

Holding Pressure and Time: This is crucial for controlling shrinkage (sinking). Sufficient holding pressure is required to compensate for shrinkage.

Sample Evaluation and Adjustment:

Dimensional Measurement: Use a coordinate measuring machine (CMM) and a 2D image measuring instrument to check critical dimensions.

Appearance Inspection: Inspect for defects such as shrinkage, flash, air bubbles, and weld lines.

Functional Testing: Perform assembly, strength, and other related tests.

Engineering Confirmation and Sample Approval: Improved samples will be submitted to you for engineering verification and your approval.

Process Parameter Locking: The final optimized parameters will be recorded in the injection molding process condition table as the mass production standard.

Fourth Stage: Mass Production and Process Control - Ensuring Stability

Ensuring that every molded product meets the standard.

Molding Cycle: Mold Closure → Injection → Holding Pressure → Cooling → Mold Opening → Ejection → Part Removal (automatically completed by a robotic arm).

Statistical Process Control (SPC):

Key Process Parameter Monitoring: Real-time monitoring and recording of injection time, peak pressure, material temperature, etc., to ensure process stability.

First Article Inspection (FAI): A comprehensive inspection of the first product at the start of each shift or after mold change.

Regular Sampling Inspection: Regular inspection of product appearance and key dimensions.

Quality Control Chart: Monitoring the stability of key product dimensions to achieve predictive management.

Phase 5: Quality Assurance and Delivery - The Final Checkpoint

Final Inspection and Packaging:

100% Visual Inspection or AOI (Automated Optical Inspection): A complete visual inspection of all products is conducted.

Protective Packaging: PE bags, bubble wrap, and partitions are used for packaging to prevent scratches and contamination.

Outgoing Quality Control (OQC): The batch to be shipped is inspected according to AQL sampling standards to ensure overall batch quality.

Document Delivery: Necessary quality documents are provided with the shipment, such as the Outgoing Quality Control Report (OQC Report) and Certificate of Conformity (COC).

Mold Maintenance and Care: Regular maintenance, rust prevention, and replacement of vulnerable parts are performed on the molds to ensure long-term stable operation.
