Plastic trophy 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 plastic trophy parts moulding 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 plastic trophy parts moulding products, we can make corresponding plastic parts, which is mainly done through injection molds.

The injection molding of plastic trophy parts requires comprehensive consideration of multiple factors, including material selection, mold design, process parameter control, and quality inspection. The following is a summary of key points:

1. Material Selection

Plastic trophies are commonly made of thermoplastics (such as ABS, PS, and PP). The appropriate material should be selected based on the intended use (decoration, collection, durability, etc.). Consider the material's physical properties (strength, temperature resistance), surface characteristics (gloss, ease of processing), and shrinkage (which affects dimensional accuracy). For example, decorative trophies require high-gloss materials (such as ABS), while shatter-resistant trophies can choose PP.

2. Mold Design (Core Step)

Trophy designs often have complex structures (such as three-dimensional shapes, parting lines, and decorative patterns). Mold design focuses on the following key points:

Design Dimensions and Specific Requirements

Parting surface design: Avoid complex shapes and set parting lines appropriately to prevent flash and infill. Planar or beveled parting surfaces are preferred. Cavity Structure: Complex curved surfaces require optimized wall thickness (generally 3-8mm). Cooling channels should be added to thick-walled areas to prevent shrinkage cavities. Ribs should be designed to avoid stress concentration.

Gating and Ejector System: Gates should be positioned away from decorative patterns, using side gates or point gates. Ejector pins or pins should be evenly distributed to prevent deformation.

Mold Material: Steel molds are preferred for large-scale production (durability, with a lifespan exceeding one million cycles); aluminum molds are suitable for small-scale production (low cost, but with consideration for wear).

Surface Treatment: High-gloss polishing or electroplating are required after molding to avoid defects such as burrs and sink marks (especially for transparent materials).

III. Process Parameter Control

Rational process parameters are key to ensuring trophy quality and production efficiency:

Parameter Type Setting Points

Barrel Temperature: Adjust according to the material (e.g., ABS is typically 210-250°C, PS 240-280°C), taking into account both melt uniformity and material properties. Injection Pressure and Speed: Complex cavities require higher injection pressure (50-120 MPa) to ensure complete mold filling; speed adjustment should be made in steps (slow injection for filling, fast injection for holding pressure).

Dwelling Time: Sufficient holding time is required (typically 10-30 seconds) to prevent shrinkage or sinking caused by cooling shrinkage.

Cooling Time: Thick-walled areas require longer cooling times (30-60 seconds), while thin-walled areas require shorter cooling times (15-30 seconds) to avoid deformation due to large temperature differences between the inside and outside.

IV. Precautions During the Molding Process

Drying: Hygroscopic materials (such as PA) require pre-drying (at 80-100°C for 2-4 hours) to prevent moisture-induced pores.

Mold Preheating: Increasing the mold temperature (50-80°C) can reduce material sticking and improve surface quality.

Production Batch Adaptation: Large-scale production requires steel molds and automated equipment (such as robotic part handling); small-scale production can use aluminum molds with manual assistance. Cycle Optimization: Use a hot runner system to minimize weld marks and reduce waste; regularly clean the screw to prevent material residue.

V. Quality Inspection and Post-Processing

Defect Detection: Focus on inspecting for issues such as short spots (incomplete injection), bubbles (air inclusion), and warpage (uneven cooling). (This can be detected using illumination or a coordinate measuring machine).

Dimension Calibration: Adjust mold dimensions based on material shrinkage (typically 0.5%-2%) to ensure the final trophy meets design requirements.

Post-Processing: After molding, gates must be cut, burrs removed, and the surface polished (e.g., mirror finish). Electroplating or spraying can be used to enhance the appearance if necessary.
