Industry data show that the injection molding of precision plastic parts, such as those used in medical product packaging and optical housings, requires tolerances as low as ±0.01 mm. To achieve these levels of performance, we generally recommend using all electric injection molding machines equipped with servo motors and/or linear guides to ensure repeatable performance.… Continue reading Which injection molding characteristics enable high-precision parts?

Using multi-compressor staged control can make water chillers both efficient and energy-efficient. Compared with a single compressor system at partial load, energy consumption per ton can be reduced by up to 30%. Generally speaking, we deploy two to four compressors to operate in stages to match the cooling capacity with the real-time load. Under staged… Continue reading What is the effect of multi-compressor staged control on energy-saving water chillers?

Weld line defects in injection moulding account for 25% of cosmetic and structural part failures and are the most common problem encountered by customers. Weld lines are formed when two melt fronts meet, and poor melt conditions can result in poor bonding or visible flaws. Troubleshooting this type of failure begins with determining the exact… Continue reading How to Troubleshoot Weld Line Failures on Plastic Injection Moulding Machine？

Up to 30% of the cycle delay in servo injection molding machine is attributed to control and drive lags, resulting in a slow response speed and a direct impact on production and product quality. Topstar uses a self-developed unified control system that integrates injection units, clamping units, auxiliary machines, and automation peripherals through a single… Continue reading How to solve the problem of slow response of servo injection molding machine？

Cycle-to-cycle variations in the injection molding process can impact part quality and production efficiency, particularly when the take-out robot is responsible for the take-out work. To solve this problem, Topstar allows the robot program, servo parameters, and mechanical settings to be modified through an intuitive manual controller or the application software, which can be adjusted… Continue reading Which features of the take-out robot can reduce cycle-to-cycle variation?

When selecting the right mold temperature controller for thick-walled automotive parts, it’s essential to understand the performance requirements. In our experience, using a 120°C high-flow water-based mold temperature controller can reduce cycle times by 12% to 15% for parts with walls thicker than 20 mm. The controller features a high-pressure pump capable of delivering up… Continue reading How to choose a mold temperature controller suitable for thick-walled automotive products?

Selecting a screw and barrel configuration for an injection moulding machine requires consideration of multiple factors, including polymer type, target shot size, cycle time requirements, and final part specifications. First, we need to evaluate the melt flow index, moisture sensitivity, and thermal stability of the product raw material, which determine the necessary plasticising capacity and… Continue reading How to choose the screw and barrel configuration for your injection moulding machine?

All electric injection molding machines are a more suitable solution for the injection molding of ultra-precision plastic parts. According to our customer feedback, electric drives can reduce position deviations by up to 40% compared to hydraulic systems under the same load. The intelligent servo drive architecture on the Topstar all electric injection molding machine reduces… Continue reading What kind of positioning accuracy can an all electric injection molding machine achieve?

During the R&D and design process, we integrated the dehumidification and drying machines into a 3 in 1 Compact dehumidifying dryer, which can provide a perfect resin drying effect for the injection molding machine. We divide the drying process into four stages, covering compressed air treatment, rapid pressure change dehumidification, ultra-dry air delivery, and sealed… Continue reading Drying process of 3 in 1 Compact Dehumidifying Dryer in injection molding

Water chillers that operate with injection molding machines must maintain a stable temperature and avoid unnecessary short cycling of the compressors to ensure optimal performance. Short cycling (i.e., frequent on and off of the compressor) shortens compressor life, increases energy consumption, and can cause system failures. We will examine how water chiller design can address… Continue reading How to prevent short cycling of the water chiller compressor?

A standalone injection molding machine cannot operate optimally without a complete set of auxiliary equipment to handle material conditioning, temperature control, and waste management, which are critical to a stable and productive molding cycle. Generally speaking, seven key auxiliary equipment are required for each large injection molding machine installation, including mold temperature controllers, chillers, material… Continue reading What auxiliary equipment does a large injection molding machine need?

Designed for precision injection molding applications, 3-axis robots are designed explicitly for pick-and-place operations. If slight vibrations during part removal can affect quality, increase cycle time, and cause unplanned maintenance. Therefore, we integrate vibration suppression functions throughout the mechanical design and control firmware of the 3-axis robot, while also considering how to adjust the speed… Continue reading How to adjust the velocity profile of a 3-axis robot to avoid vibration?
