Injection molding robots are essential machinery used in plastic injection molding processes. For those considering purchasing these robots, it’s important to understand the machine’s performance and evaluate which factors contribute to selecting the right one. Below, we outline three key aspects to consider when choosing an injection molding robot:

Technical Specifications

When selecting an injection molding robot, it’s crucial to evaluate the technical parameters in both vertical and horizontal comparisons. The “vertical” refers to the robot’s core technical specifications, which should meet industry standards and be verified accordingly. The “horizontal” involves comparing the robot’s parameters to those of similar machines, both domestically and internationally.
This is a meticulous process that depends on factors such as the material, shape, structure, and application of the molded product. It’s also essential to consider aspects such as the robot’s structural quality, precision, cavity count, mold type, and the dimensions of the mold. Additionally, you should assess the production capacity, automation level, and the overall design based on daily, monthly, and annual production requirements.

Choosing the Manufacturer

It is advisable to select a manufacturer with local after-sales service points. The complexity of injection molding robots means that accessible maintenance services are essential. When purchasing, avoid focusing solely on the price. The price gap between domestic and imported robots can be significant, so it’s crucial to understand what brand of components the manufacturer uses. While some components, like seals and bearings, may not be visible, the reputation and reliability of the manufacturer play a critical role in ensuring long-term product performance.
Moreover, a reputable manufacturer with good customer feedback can offer peace of mind, especially regarding spare parts and service availability.

Energy Efficiency and Environmental Impact

With the rapid advancements in technology, energy efficiency and environmental sustainability have become crucial factors in evaluating modern injection molding robots. Energy-saving features primarily focus on systems like the heating (e.g., electromagnetic heating), drive (e.g., frequency converters, servos), and cooling systems, which contribute to energy and water conservation.
Modern robots should also prioritize “eco-friendliness,” preventing issues like hydraulic oil leakage and excessive noise during operation. Additionally, the materials used in the robot’s construction should be environmentally friendly.

When purchasing an injection molding robot at a reasonable price, it’s also important to consider its ease of maintenance and repair. The installation of various components, including mechanical, hydraulic, electronic, and electrical parts, should facilitate smooth maintenance. Standardization and compatibility are vital when selecting the right robot model.

Two key parameters to consider in choosing an injection molding robot are injection volume and clamping force. To ensure product quality, the actual weight of the mold should be within 70% of the machine’s theoretical injection volume. It’s also important to verify whether the distance between the machine’s columns, the mold opening stroke, and the mold thickness are suitable for the chosen mold.
