How to adjust the velocity profile of a 3-axis robot to avoid vibration?

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?

How to achieve micro-precision tolerances with precision injection molding machines?

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?

How to Ensure Scale-Free Operation in Hard Water Areas with Water-Type Mould Temperature Controllers？

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？

What defects of injection molding can the all electric injection molding machine solve?

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?

How to increase the injection rate of plastic molding machines?

When pursuing the goal of increasing the output of plastic molding machines during injection molding, one key factor that needs improvement is the injection rate. The injection rate is the speed at which the molten resin is pressed into the mold, and it is also one of the key factors that determine the cycle time… Continue reading How to increase the injection rate of plastic molding machines?

The trade-off between payload and speed of the injection molding robot

The key to selecting the right injection molding robot for your injection molding machine is to strike a balance between payload and speed. Payload refers to the maximum weight that the injection molding robot can carry, while speed refers to the speed at which the arm moves along its axis. Both factors directly affect cycle… Continue reading The trade-off between payload and speed of the injection molding robot

Importance of Injection Moulding Machine Frame Rigidity

Frame rigidity refers to the ability of the machine’s structural frame to resist deformation under load. When the injection moulding machine applies high clamping and injection pressures, the frame must maintain its shape to ensure the mould is accurately aligned. Any slight deviation can result in flashing, under-injection, or uneven part filling. Additionally, a rigid… Continue reading Importance of Injection Moulding Machine Frame Rigidity

How to avoid the deviation load of a large injection molding machine?

Deviation loads are often encountered when operating large injection molding machines, where unexpected lateral forces cause the injection cylinder to deviate from its center. These loads can originate from uneven melt pressure in the injection molding machine, inconsistent clamping force, or slight wear of the guide components. When the molten plastic rushes into one side… Continue reading How to avoid the deviation load of a large injection molding machine?

Diagnosing Inconsistent Shot Weights in an All Electric Injection Molding Machine

Unlike hydraulic machines, where pressure variations and fluid compressibility can cause inconsistencies, all electric injection molding machine utilize servo motors and precision ball screw mechanisms to meter polymers. However, even these energy-efficient injection molding machines can experience shot weight fluctuations due to mechanical, thermal, or control-related factors. So we need to diagnose and eliminate the… Continue reading Diagnosing Inconsistent Shot Weights in an All Electric Injection Molding Machine

How to prevent the screw of plastic injection molding machine from slipping?

Screw slippage in plastic injection molding machine poses a serious threat to process stability and part quality. Slippage occurs when the screw’s flights lose their grip on the molten polymer in the barrel, resulting in inconsistent shot sizes, poor melt homogeneity, and fluctuating injection pressures. First, identify the symptoms, which typically manifest as a sudden… Continue reading How to prevent the screw of plastic injection molding machine from slipping?

Tips for checking wear of rack and pinion of injection robot?

Injection robot that are calibrated before injection molding production can ensure fast and repeatable part pick and placement. The core of one of them is the rack-and-pinion transmission mechanism. However, over time, the continuous meshing between the rack teeth and the pinion will cause metal fatigue, pitting and dimensional wear. Therefore, rack and pinion wear… Continue reading Tips for checking wear of rack and pinion of injection robot?
