INJECTION MOLDING MACHINES FOR PET PREFORMS AND CAPS
Top Unite is committed to providing high-performance plastic injection molding machines for the production of PET bottle preforms and caps. Leveraging our extensive practical experience in the field of food and beverage packaging, we offer comprehensive injection molding solutions to our customers, assisting in optimizing production lines, achieving outstanding production efficiency, helping you lead the industry and achieve greater revenue.
HOW TOP UNITE MEETS THE DEMANDING REQUIREMENTS OF PET PREFORM AND CAP MANUFACTURING
PET preform and cap injection molding requires exceptional precision, repeatability, and production efficiency to ensure consistent product quality and high-volume output. In addition, manufacturers must meet stringent quality and hygiene standards, particularly ensuring precise cap dimensions to achieve excellent sealing performance. Top Unite injection molding machines deliver outstanding stability, precise shot control, and excellent repeatability in every production cycle, helping manufacturers achieve higher product quality and production yield.
Beyond machine performance, Top Unite also provides complete production planning and engineering support for PET preform and cap manufacturers. We recommend optimized machine configurations based on the characteristics of the customer's products and production needs, while also assisting with the integration of peripheral auxiliary equipment, effectively reducing the customer's integration costs and time investment, and achieving faster mass production goals.

Top Unite provides container injection molding machines for food and beverage.

Plastic-Caps Special Plastic Injection Molding Machine
EH-DS Series (50~750 TON)
Plastic-cap special plastic injection molding machine is designed against the food packaging industry. The machine builds in a PP and PE special double thread material barrel. It helps to compound with color masterbatch during the material is plasticizing to reduce the defective products.To save more time, we place a proportional valve to boot up the speed in the mold closing/opening and make it more accurate to protect your mold. Meanwhile, we strengthen the clamping toggle structure to bear the high pressure from high-speed mold closing/opening which extends the service life.

Medium and large size Hydraulic Plastic Injection Molding Machine
EH Series (180~750 TON)
Medium and large-size Hydraulic Plastic Injection Molding Machines ranging from 180ton to 750ton has the mainly hydraulic system configures an Electro-hydraulic proportional system to control the oil flow and pressure. It has responsive and high-consistency features. Via the Lvdt spool receives the feedback signal and modifying output, lets the users get a hydraulic pressure closer to the actual situation, and helps the users grasp the control of injection parameters. The power resource is from a double fixed vane pump. The main hydraulic system can provide a high-flow source via pumps' confluent, which gives an advantage to booting up the speed of the machine.The traditional-hydraulic system has two features, one is high-pressure resistance, and second is it can provide a long holding time. So the traditional injection machine is more suitable for making thick parts, transparent parts, products that require a smooth surface, or materials that need high-pressure holding.

Medium and large size Hybrid Plastic Injection Molding Machine
EH-DS Series (180~750 TON)
The Hybrid Plastic Injection molding machine (180ton to 750ton medium and large size) equips a high-performance servo motor, which also achieves an outstanding energy-saving effect. With a rapid response and pressure output linear feature, easy to reach every requirement given by the user. It reduces the motor r.p.m when during the low flow is required and the product cooling to save the energy consumption. Comparing with the conventional hydraulic injection machine, it saves 60% energy at least.
