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?

Precision injection molding machines are capable of producing parts with micro-tolerances. This micro-precision tolerance (usually ±0.01 mm or less) is crucial for the production of products such as medical devices, micro-optical devices, and precision connectors. Such precision injection molding machines utilise electric drives to achieve ultra-precision motion, employ low-damping injection units to provide sensitive pressure… Continue reading How to achieve micro-precision tolerances with precision injection molding machines?

Using a mould temperature controller in areas with poor water quality can cause scaling on heaters and internal channels, significantly reducing heat transfer efficiency and resulting in uneven mould temperatures, extended cycle times, and costly downtime. Therefore, achieving scale-free operation in these areas is not only an added advantage but also a prerequisite for continuous,… Continue reading How to Ensure Scale-Free Operation in Hard Water Areas with Water-Type Mould Temperature Controllers？

Working with hydraulic injection molding machines is prone to injection molding defects such as warpage, material shortages, and dents, which can be reduced by switching to all electric injection molding machines. They are electrically driven and can provide tighter control over every stage of the entire process. At the same time, all electric injection molding… Continue reading What defects of injection molding can the all electric injection molding machine solve?
