The molding process for plastic motorcycle parts requires a comprehensive consideration of material properties, mold design, and injection molding techniques. The following describes the specific process and key steps:
1. Material Selection and Pretreatment
Thermoplastics (such as ABS, PP, and PS) are commonly used for motorcycle parts. Selection should be based on the part's function (e.g., decorative effect and strength requirements):
ABS: Offers excellent overall performance, impact resistance, and easy molding, making it suitable for exterior parts (e.g., handlebars and instrument panels);
PP: High-temperature resistance (up to 100°C) and chemical resistance make it suitable for impact-resistant components (e.g., engine guards);
PS: Offers excellent transparency and is used for decorative parts (e.g., transparent covers).
Pretreatment: Hygroscopic materials (e.g., PA) require pre-drying (at 80-100°C for 2-4 hours) to prevent pores. This step can be omitted for non-hygroscopic materials (e.g., ABS).
2. Mold design and manufacturing (core link) Mold quality directly affects the molding effect of parts, and the following design points need to be focused on: 1. Mold structure design Parting surface: Planes or inclined surfaces are preferred to avoid complex shapes that lead to flash or insufficient filling; motorcycle parts (such as headlight covers and decorative parts) mostly use plane parting [3]. Cavity and core: Complex curved surfaces need to optimize wall thickness (3-8mm), and cooling channels should be added to thick-walled areas to prevent shrinkage holes; rib design should avoid stress concentration (such as the support structure of trophy parts) [3]. Material selection: Steel molds (such as H13, S136, with a service life of over one million times) are selected for large-scale production; aluminum molds can be selected for small-scale production (low cost, but attention should be paid to wear). 2. Auxiliary system design Gate and ejector: Gates should avoid decorative patterns (such as handlebars) and use side gates or point gates; ejector pins/ejector pins should be evenly distributed to prevent deformation. Cooling system: Injection molding requires the design of a sufficient cooling circuit (such as circulating water cooling). The recommended mold temperature for PP parts is around 80°C (weld marks are likely to form below 40°C, and warping is likely to occur above 100°C). 3. Manufacturing technology Promote CAD/CAM/CAE technology and optimize mold structure through 3D modeling; hot runner technology can reduce the waste of raw materials (applicable to multi-cavity molds). III. Injection molding process 1. Material heating and plasticization Granular plastic enters the feeding chamber through the hopper and is heated and mixed by a reciprocating screw (spiral screw) (the temperature is adjusted according to the material, such as ABS 210-250°C). After melting, a uniform plastic melt is formed [2]. 2. Injection into the mold cavity The injection molding machine quickly injects the melt into the mold cavity at high pressure (50-120MPa). The filling process needs to control the speed (slow injection to fill the mold, fast injection to maintain pressure) to ensure that complex structures (such as the curved surface of the headlight cover) are completely filled [2][3]. 3. Cooling and solidification
The melt is cooled and hardened in the mold cavity. The time is adjusted according to the thickness of the part (30-60 seconds for thick walls and 15-30 seconds for thin walls) to avoid deformation caused by excessive temperature difference between the inside and outside [3].
4. Demolding and trimming
After cooling, the mold is opened to remove the part, the gate (such as side gate, point gate) is cut off, the burrs are ground, and polished if necessary (such as transparent parts need mirror treatment).
IV. Quality control and post-processing
Defect detection: Focus on checking short spots (insufficient filling), bubbles (air mixing), and warping (uneven cooling). This can be verified by light or three-dimensional coordinate measuring machine.
Dimension calibration: Adjust the mold size according to the material shrinkage rate (usually 0.5%-2%) (such as PP shrinkage rate is about 1.0%-1.5%) to ensure that the final part meets the design requirements.
Surface treatment: Decorative parts require high-gloss polishing or electroplating (such as handlebar decorative strips); functional parts (such as engine cooling fins) can be sprayed or baked to enhance durability.
