#Three-axis servo Robot 50kg load test# Heavy-duty injection molding robot mold gripping performance

Load capacity is the core indicator for evaluating whether a 3-axis servo robotic arm can adapt to large-size mold and product picking scenarios. ZHIYI’s Bull Head 3-Axis Servo Robotic Arm is designed for the pain point of low load capacity of traditional 3-axis manipulators in the market. The test data is as follows:

Test Load	Operation Stability	Mold Picking Success Rate	Adapted Product Scenarios
20kg (standard load)	No shaking or offset during operation	100%	Household appliance shells, 3C product frames
35kg (medium load)	Stable movement, no abnormal noise in the transmission system	99.8%	Auto interior parts, large plastic containers
50kg (maximum load)	Smooth lifting and transferring, the servo motor torque output is stable	99.5%	Complex molds, new energy vehicle battery shell blanks

Test Analysis:

1. Compared with the mainstream 3-axis servo manipulators in the market with a maximum load of 30kg, ZHIYI’s product has a 67% higher load capacity, which can meet the picking needs of large injection molding products and complex molds in European and American auto parts and household appliance industries .
2. Under the maximum load of 50kg, the success rate of mold picking is still as high as 99.5%, which is far higher than the industry average of 95%. The closed-loop control system of the servo motor can adjust the torque in real time according to the load change, avoiding the problem of falling or shaking of heavy objects.
3. For small and medium-sized enterprises in Europe and America that need to cover both small-batch precision products and large-batch heavy-load products, this product can realize “one machine for multiple uses” and reduce the cost of purchasing multiple sets of equipment.

Positioning Accuracy Test: ±0.1mm Precision Meets High-End Injection Molding Needs #Injection Molding Robot Repeatability # High-Precision Three-Axis Servo Robot for Electronic Component Injection Molding Positioning accuracy directly determines the qualification rate of precision injection molding products. In this test, ZHIYI’s 3-axis servo manipulator was tested for repeated positioning accuracy in the scenario of embedding metal inserts, and the data was compared with traditional pneumatic manipulators and hydraulic manipulators:

Manipulator Type	Repeated Positioning Accuracy	Insert Embedding Qualification Rate	Applicable Precision Scenarios
ZHIYI 3-Axis Servo Robotic Arm	±0.1mm	99.9%	3C product connectors, auto sensor components
Traditional Pneumatic Manipulator	±0.3mm	92%	Ordinary plastic parts, non-precision components
Hydraulic Manipulator	±0.08mm	99.7%	High-precision molds, high cost

Test Analysis:

1. The repeated positioning accuracy of ZHIYI’s 3-axis servo manipulator reaches ±0.1mm, which is 3 times higher than that of traditional pneumatic manipulators, meeting the precision requirements of most high-end injection molding products in Europe and America . Although it is slightly lower than that of hydraulic manipulators, its purchase and maintenance costs are only 50% of those of hydraulic manipulators, which is more cost-effective for SMEs.
2. In the insert embedding test of 3C product connectors, the qualification rate is as high as 99.9%, which can effectively avoid the problem of product scrapping caused by inaccurate positioning. This performance is particularly suitable for the European and American electronic component manufacturing industry, which has strict requirements on product precision.
3. The high-precision transmission structure of the manipulator (adopting Q235 high-strength material) ensures that the accuracy does not drift after 10,000 repeated operations, which is far higher than the industry standard of 5,000 operations .
