Choosing the right injection molding robot requires careful attention to several key details. Below are some of the most important factors to keep in mind:

Technical Specifications

When selecting an injection molding robot, it’s essential to evaluate both vertical and horizontal technical parameters. “Vertical” refers to ensuring that the robot’s core specifications meet industry standards and are certified according to those standards. “Horizontal” involves comparing the technical specifications of similar robots from both domestic and international manufacturers. This is a detailed, scientific process that should take into account the materials, shape, structure, application, and specific requirements of the molded products. Additionally, factors such as mold structure, cavity count, type of runner, size, and production capacity (daily, monthly, and yearly) should be considered. The robot’s automation level and precision are also key elements in the decision-making process.

Choosing the Manufacturer

It’s crucial to select a manufacturer like Wensui group that has local after-sales service points. Injection molding robots have complex structures, so convenient access to maintenance and support is essential. When purchasing, avoid choosing solely based on the lowest price. The cost difference between domestic and imported robots can be substantial. It’s also important to understand the brand of components used by the manufacturer . While some parts like seals and bearings might not be visible, the reputation, credibility, and customer feedback about the manufacturer play a vital role in your decision-making process.

Energy Efficiency and Environmental Considerations

As technology continues to advance, energy efficiency and environmental impact have become critical factors in selecting modern injection molding robots. Energy savings are reflected in various systems such as the heating system (using electromagnetic heating), the power drive system (featuring frequency converters and servo motors), and the cooling system. Modern robots should be designed with an emphasis on sustainability. This includes minimizing hydraulic oil leaks, reducing noise, and using environmentally-friendly materials. Additionally, ensure that the robot is easy to maintain and repair, which will help you save time and costs in the long run.

Maintenance and Repair Convenience

The installation positions of mechanical, hydraulic, electronic, and electrical components should be optimized for ease of maintenance and repair. Consider selecting robots with standardized parts, as this can make repairs simpler and reduce the complexity of replacement parts.

Machine Capacity and Locking Force

Two crucial parameters for an injection molding robot are injection capacity and locking force. To ensure product quality, the actual weight of the mold should ideally be within 70% of the machine’s theoretical injection capacity. It’s also essential to calculate the required locking force based on the mold’s projected area. Special attention should be given to the machine’s column spacing, opening stroke, and whether the mold thickness suits the robot’s capabilities.

By paying attention to these details, you can choose an injection molding robot that aligns perfectly with your production needs, offering optimal performance, energy efficiency, and ease of maintenance.
