plastic molding machine 12-1

Producing complex and precise plastic parts is a key task in optics, consumer electronics, and consumer goods. In the face of the wave of digitalization, intelligence, and automation in the manufacturing industry, many companies have introduced advanced intelligent plastic molding machines to create highly automated workstations and production lines to meet the needs of high-quality, high-precision products and undertake high-value-added product orders. The plastic molding machine solutions provided by Topstar for four different products are listed below.

Plastic molding machine: Aspheric thick-walled lens solution

Aspheric thick-walled lenses are often used in optical devices and camera systems, where precision and clarity are critical. However, producing such lenses is not without challenges. During the molding process, problems such as air marks, bubbles, and shrinkage are prone to occur, all of which affect the quality of the final product. To solve these problems, Topstar has proposed a dedicated plastic molding machine solution, the core of which is a plastic molding machine with extremely low injection speeds and high-pressure holding functions. The low injection speed helps prevent the formation of excessive bubbles, while the high-pressure holding performance ensures that the thick-walled lenses do not shrink. In addition, we also use special optical screws to achieve adequate mixing and degassing, prevent material contamination, and ensure that transparent products do not turn yellow.

Plastic Molding Machine: LED Display Shield Solution

The production of LED display shields presents many challenges, including the risk of defects such as masking, lack of glue, deformation, and breakage during the molding process. These defects can significantly reduce the quality and reliability of the final product.

To overcome these challenges, Topstar used electric plastic molding machines with high-speed injection tables, high-precision metering controls and optimized machine components. Its IU430hs has an injection speed of up to 400mm/s and an acceleration of up to 2g. This high-speed capability ensures that the material is injected quickly and accurately, minimizing the possibility of deformation. In addition, high-precision metering controls are used to regulate the amount of material injected into the mold, ensuring that the LED display shield has the correct thickness and density. This reduces the risk of defects and ensures that the final product is strong and durable.

Mobile power housing and automatic nut embedding

The production of mobile power housing and automatic nut embedding involves multiple steps, requiring precise control of the molding process and integrating other components. This solution used a direct pressure servo drive plastic molding machine (TH550). It can better control the molding process. The machine features a high-precision clamping structure that ensures smooth opening and closing of the mold, minimizing the risk of part deformation. The deformation of the template in this solution is as small as 0.2mm/m, which can extend the service life of the mold by more than 30%.

In addition, the solution uses intelligent automation technology to improve quality and efficiency. The robot mold opening position tracking compensation function ensures that the nut embedding process meets the required position accuracy, even for different nut specifications or planes. At the same time, the control system software developed by Topstar standardizes the embedding function, which can efficiently and accurately integrate the nut into the molded part.

Mobile phone case injection molding solution

The mobile phone case injection molding solution uses the TS130 hinge servo drive plastic molding machine, which provides several advantages for this application. The template deformation is as low as 0.2mm/m, ensuring the molded part maintains its shape and dimensional accuracy. The machine’s high rigidity and strength make it ideal for producing precision parts that must withstand the rigors of daily use.

They have a maximum injection speed of 145mm/s and an injection pressure of 310MPa, more than 30% higher than standard machines. These enhanced parameters enable the production of mobile phone cases with high precision and smooth surface finish. In addition, the use of advanced dedicated screw components ensures that the plastic molding machines can handle the demanding conditions of commonly molded materials such as PC and TPU for mobile phone cases.

Improved product precision and surface quality

One of the main benefits of using plastic molding machines to produce complex precision plastic parts is their ability to achieve high levels of product precision and surface quality consistently. Whether it is consumer electronics, automotive parts, or medical devices, it is critical to ensure that each part meets strict dimensional tolerances and surface finish requirements.

Topstar’s plastic molding machines have self-developed control systems integrated with peripheral auxiliary machines to adjust temperature, pressure, and injection speed to ensure the plastic material flows smoothly and evenly into the mold. This precision is essential for parts with complex geometries or tight tolerances, where even the slightest deviation can cause defects in the part. At the same time, specialized screw designs, temperature control systems, and high-pressure holding mechanisms for special requirements help achieve the required level of precision. These features can minimize problems such as material degradation, uneven cooling, and inconsistent molding to improve product quality.

Injection molding production that meets high-precision molding requirements

Topstar’s injection molding equipment has enabled the company’s products to achieve high-end and solved the company’s problems in product quality. From aspherical thick-walled lenses to mobile phone cases, plastic molding machines provide the precision, reliability, and versatility required to meet the demanding needs of modern manufacturing. These machines can produce high-quality parts that meet the most stringent industry standards by combining advanced features such as low injection speed, high-pressure maintenance, precision metering control, and automation.
