Custom plastic moulded parts moulding

In addition, our company has established cooperative relationships with plastic raw material suppliers, printing manufacturers, etc. to ensure the supply of raw materials and printing quality. Through our rich experience and perfect supply chain, our company can provide customers with high-quality customized custom plastic moulded parts products to meet their specific needs. At the same time, we have 10 years of professional foreign trade service experience, understand the foreign trade process, and better serve our customers. For custom plastic moulded parts products, we can make corresponding plastic parts, which is mainly done through injection molds.

Phase One: Requirements Analysis and Design freezing

This is the cornerstone of the project, with the goal of "getting it right the first time".

In-depth demand communication

Functional requirements: Usage environment, mechanical properties (strength, toughness), temperature resistance, chemical resistance, flame retardancy (UL94), electrical performance, etc.

Appearance requirements: Surface texture (high gloss, matte, etched texture), color standard (such as Pantone color number), assembly surface requirements.

Precision and compliance: Critical dimensions and tolerances (GD&T), assembly interfaces, industry certifications (FDA, ISO 13485, RoHS, etc.).

Business objectives: Target cost, project schedule, life cycle production estimate.

Manufacturability design analysis

Core collaboration: The design team of the mold manufacturer works in coordination with the customer.

Key points of analysis

Wall thickness uniformity: It is recommended to be 2-3mm to avoid shrinkage and warping.

Demolding slope: Ensure smooth demolding, usually ≥1°.

Reinforcement rib and pillar design: Follow the principle of "60% flesh thickness" to prevent shrinkage marks.

Parting line planning: Determine the optimal position and balance appearance and function.

Pre-review of the gating system: Evaluate the position and type of the gate and optimize the filling.

Deliverable: DFM report, including detailed modification suggestions. The design will be frozen upon written approval by the client.

Material selection

Recommend resins (such as ABS, PC, PP, PA, POM, etc.) according to requirements, and provide material data sheets and certification information.

Phase Two: Mold Design and Manufacturing

Molds are the core assets that determine the quality of parts and production efficiency.

Mold design

Mold flow analysis: A key step. Through CAE simulation to predict filling, cooling, shrinkage and warpage, potential defects (cavitation, weld marks, shrinkage) can be addressed in advance, and the flow channel, cooling and pressure holding schemes can be optimized.

Structural design: Complete the full set of design including the mold base, cavity/core, slider/inclined top, cooling water circuit and exhaust system.

Precision machining and assembly

Processing: High-precision processing is carried out using processes such as CNC, EDM, and slow wire electrical discharge machining.

Surface treatment: Mirror polishing or etching treatment is carried out as required.

Assembly and debugging: Precision assembly is carried out by senior fitters to ensure the smooth operation of all moving mechanisms.

Phase Three: Mold testing and process Optimization

At this stage, the mold is verified and the mass production process benchmark is established.

First mold trial: Debug using production materials to produce the first batch of samples.

Sample evaluation and process debugging

Dimensional inspection: Use a three-coordinate measuring machine for full-size comparison.

Appearance and function inspection: Verify the appearance standards and assembly performance.

DOE Process Optimization: The system adjusts parameters such as temperature, pressure, and speed to lock in the optimal process window.

Project approval: The customer signs and approves the sample, and the marking design and process are frozen.

Documentation: Output the final injection molding process card and inspection instruction manual.

Phase Four: Mass Production and Process Control

Ensure the long-term stability and consistency of production.

Standardized production

Operate strictly in accordance with the locked process parameters.

Automated pick-up and packaging are achieved by using mechanical arms.

Statistical Process control

Key parameter monitoring: Real-time monitoring of injection time, peak pressure, etc.

First piece inspection: To be carried out each shift or after mold change.

SPC control chart: Conduct statistical monitoring of key dimensions to achieve preventive quality control.

Phase Five: Quality Assurance and Delivery

Final inspection

100% visual inspection or AOI automatic optical inspection.

Functional spot checks.

Packaging and delivery: Customized packaging that is scratch-resistant and anti-static is adopted, and delivery is made on time.

Document delivery: Provide complete quality documents such as shipment inspection reports and material certificates.

Mold maintenance and after-sales service: Regular maintenance and technical support are provided.
