How to choose the price of servo robotic arms for injection molding machines

一、Core Factors Affecting the Price of Injection Molding Machine Servo Manipulators

1. Load Capacity: The Core Factor Determining the Basic Price

• Light-load manipulators (≤10kg): Suitable for small and lightweight injection molding products such as plastic parts and electronic components. The mechanical structure and transmission system are relatively simple, and the price is relatively low, generally ranging from 30,000 yuan to 80,000 yuan.
• Medium-load manipulators (10 - 30kg): It is applicable to the production of daily necessities such as plastic containers and auto parts accessories. It needs to be equipped with high-performance servo motors and reducers, and the price is mostly between 80,000 yuan and 150,000 yuan.
• High-load manipulators (>30kg): Targeted at large and complex injection molding molds and products, represented by the Bull Head 3-Axis Servo Robotic Arm of ZHIYI, with a maximum load of 50kg. Its mechanical structure needs to adopt high-strength materials, and the drive system needs to be matched with high-power components, so the price is relatively high, generally above 150,000 yuan. However, its high load capacity can meet the needs of picking up complex molds and large products, which is very suitable for large injection molding enterprises pursuing high efficiency.

2. Axis Configuration: Balancing Precision and Price

• 3-axis servo manipulators: Taking ZHIYI's WKG-1000 three-axis single-arm single-section robot arm as an example, it has the characteristics of simple structure, fast operation and high cost performance. It is suitable for simple injection molding product taking and placing operations. The price range is mostly 50,000 yuan to 120,000 yuan , which is the first choice for SMEs to realize automation transformation and reduce costs by up to 30%.
• 5-axis dual-arm servo manipulators: It has higher flexibility and precision, can complete complex operations such as in-mold labeling and in-mold inserts, and is suitable for high-end injection molding production lines. According to market data, the price of 5-axis servo manipulators is mostly between 120,000 yuan and 300,000 yuan。 ZHIYI's 5-axis dual-arm double-intercept robot has the advantages of high precision and stable operation, and is very suitable for injection molding enterprises with high requirements for product processing accuracy.

3. Customized Requirements: The "Increment" of Price

      Non-standard customization fee: For manipulators that need to be adapted to special injection molding machine tonnage, product size or production process, the customization fee usually accounts for 15% - 25% of the total price . This part of the cost is mainly used for structural redesign, system debugging and component matching.

     Certification cost: For enterprises that need to export products, CE and ISO9001 certification are essential. The       certification cost usually accounts for 8% - 12% of the product price . ZHIYI's products have passed the above two       certifications, and undergo rigorous testing before leaving the factory, which ensures the reliability and safety of the   products and saves the subsequent certification cost for purchasers.

三、High-Cost-Effective Procurement Skills: Focus on Total Cost of Ownership (TCO)

1. Match the Manipulator with Injection Molding Machine Tonnage and Product Size

• For 60T - 120T small injection molding machines, 3-axis light-load manipulators can meet the production needs;
• For 160T - 320T medium and large injection molding machines, 5-axis manipulators are more suitable for complex operations such as in-mold inserts 伯朗特机器人股份有限公司;
• For large injection molding machines above 320T, high-load bull head manipulators are the best choice to ensure stable and efficient production.

2. Evaluate Energy Consumption and Maintenance Costs

• The servo motor and reducer are the core components of the manipulator, accounting for about 35% of the total cost . Choosing manipulators with high-quality core components can reduce the frequency of maintenance and replacement;
• ZHIYI provides 24/7 pre-sales consultation and after-sales technical support for global customers, ensuring that the manipulators can be maintained and repaired in time, reducing the downtime loss of the production line.

3. Prioritize Brands with Rich Project Cases and Technical Patents

4. Consider the Leasing Trial Scheme for Budget-Limited Enterprises

四、Avoid Price Traps: Don't Be Blinded by Low Prices

1. Uncertified products: Low-price products often lack CE and ISO9001 certifications, which not only have potential safety hazards, but also cannot meet the export standards, resulting in the inability of products to be sold overseas;
2. Hidden costs of non-standard transformation: Some suppliers do not inform the additional debugging costs during the quotation period. In the later stage, enterprises need to pay 15% - 25% of the transformation costs for the mismatched manipulator and production line ;
3. Software upgrade fees: Some manipulators need to pay 20,000 - 30,000 yuan of annual authorization fees for software upgrades . Purchasers should confirm whether the supplier provides free software upgrades when purchasing.

五、Conclusion: Choose the Right Manipulator, Not the Expensive One
