High Precision Injection Molding Machine for Automotive Lighting
Today, there are many companies who manufacture a wide range of plastic parts and components for the automotive industry. With the rising demands in the automotive industry, the high quality of the manufactured parts, maximum availability of the production systems and stable processes are important. Among all the categories of auto parts, the car lighting has been considered as a high-precision and challenging injection molding product. There are both exterior and interior automotive lighting applications that are all best accomplished with lenses, covers, and housings created through the plastic injection molding manufacturing process. Due to its complicated mold design and strict inspection, the manufacturers must decrease the defect rate.
Moreover, there are some trends that need to be aware of, such as LED technology, complex shapes and designs of products, material innovation, and the development of intelligent and automation capabilities. These trends will guide injection molding machine manufacturers to continuously improve processes and technologies to meet market demands and the development of the automotive industry.
In this article, we are going to introduce the TPIIR injection molding machine, designed specifically for high-precision automotive lighting production.
1. Special design of turntable
The turntable of the injection molding machine is one of the key elements to achieve high precision in the automotive lighting producing process. With the special design, the turntable can avoid tilting and ensure its accuracy of position.
2. European servo motor system & controller
To raise speed without decreasing accuracy, our TPII uses a European servo motor system. Moreover, with a European controller, it can bring more flexibility to fit complex mold design and to operate multiple actions. Especially for modern car lights, which become more complex shaped and unique designed to enhance aesthetics and lighting effects.
3. Single cylinder injection molding system
With simplicity, the single cylinder injection molding system offers more flexibility in operation. Operators can adjust the injection parameters based on product requirements to meet different production needs. Besides, it ensures the stability of injection and keeps precision while producing automotive lighting. Due to strict quality control of car lights, manufacturers need to possess high-precision molding techniques to meet these complex requirements.
4. Special design of screw
When we use a PC as the raw material to car light, considering its characteristics, a specially designed screw is a way to solve. Due to its high viscosity and low fluidity, you need an injection molding machine with high injection pressure. If the pressure is too low, the surface would not be smooth. Then, to ensure excellent quality, we use a specially designed screw with a smooth surface where the material can easily pass through. This ensures that the raw material won’t get stuck in the screw or barrel which might cause black specks.
5. Two-platen designed & Multi-color designed
With more complicated and diverse designs of car lights showing up, the flexibility of customization is a profitable option. TPIIR is a two-platen plastic injection molding machine, which provides more flexibility of customization due to its structure. And it can also be customized as a multi-colored machine. With our wide experience in customization, CLF has developed 2 color 2 stage, 3 color 2 stage, 3 color 3 stage, 4 color 4 stage, 4 kinds of machines for car lights production.
Case study：1800TPIIR plastic injection molding machine for automotive lighting
One success story involves a partnership with a leading Taiwanese brand of automotive lighting. The company
developed a new car light mold, which needs 4 injection units. However, they requested not only multi-color design
but also asking for a machine that can inject two, three, and four components. Furthermore, the diameter of the
turntable needs to be longer than 2200mm but the length of the machine has to be shorter than the 1600T machine.
Based on their needs, the turntable was designed to turn in 90, 120 and 180 degrees, which could fit a different mold in two, three or four components. Besides, with a European controller, the operation of the machine would be more flexible. In the end, this highly customized multi-color injection molding machine successfully operated in the first test.
To sum up, automotive lighting is one of the high-precision auto parts to produce. With diverse appearance, complex mold design and new technology for car headlight presents a bigger challenge for manufacturers to improve their production process. An injection molding machine with special design of turntable and screw, it can decrease defective rate. Using a single cylinder injection system, European servo motor and controller to keep stability, raise precision and create flexibility to operate more complex processes. Moreover, customized as two-platen design or multi-color/component is one of the options to optimize your production. However, among all the features, to achieve a high-precision automotive lighting production solution, the TPIIR series may be the most valuable investment.
