Due to its unique spatial location, the instrument panel is increasingly distributed with operational functions that not only reflect the basic driving status of the vehicle, but also the control of the vents, audio, air conditioning and lighting gives more safety and driving pleasure. Therefore, the instrument panel has safety, functionality, comfort and decoration. First of all, it needs a certain degree of stiffness to support its attached parts for proper operation at high speed and vibration; and it also needs better energy absorption to reduce the impact of external forces on the front and passenger side in the event of an accident.
The dashboard usually includes parts such as dashboard body (shell), instruments, air-conditioning control system, air duct/air outlet, operation panel, switches, sound control system, defroster, defogger, glove box, left cover, decorative plate, etc. Most dashboards also include accessories such as storage box, driver’s glove box, speakers, and functional parts such as clock, metal reinforcement, ashtray, cigarette lighter, cup holder, etc.; some mid- to high-end cars Adopt high-end product design such as satellite navigation system, cell phone intercom system, temperature sensing system, etc.
Today we come together to learn about hard plastic instrument panels, which are made of rigid plastic by injection molding process and are widely used because of their simple process and low investment, some or all of which are coated with decorative paint or soft-touch paint to improve the appearance, tone or texture. Blister dashboards are molded or pressed outside the frame to absorb bonded skin or laminate skin during injection molding to give them a skin-like appearance. made by the traditional artificial skin process.
The main process steps of instrument panel of auto plastic parts mold.
Hard plastic instrument panel: injection molding (instrument panel body and other parts) → welding (main parts) → assembly (related parts).
Auto parts dashboard is a widely used processing technology for dashboard by cutting dry plastic particles in injection molding machine and melting them by heating in a barrel to manufacture hard plastic dashboard body, plastic and soft plastic dashboard skeleton and most other related parts. Hard plastic dashboard materials mostly use PP, while dashboard skeleton materials mainly include PC/ABS, PP, SMA, PPO (PPE) and other modified materials. Other parts are made of ABS, PVC, PC, PA and other materials according to different functional, structural and appearance requirements. Injection molding technology has been increased, modified and selected for different applications of equipment, resulting in multiple sub-processes such as gas-assisted injection molding, sequential valve injection molding, compound injection molding, insert injection molding, two-color injection molding and secondary injection molding.
