Actual test report on the operation data of the servo robot arm of a three-axis injection molding machine.

In the era of Industry 4.0, the injection molding industry is undergoing a global automation transformation. Labor shortages, rising production costs, and the demand for high-precision products are driving manufacturers to seek reliable servo Robotic Arm [https://www.zhiyirobotics.com/robotic-arm/] solutions. As a professional provider of intelligent manufacturing systems for injection molded products, ZHIYI [https://www.zhiyirobotics.com/about-us/]has conducted a full-dimensional performance test on its flagship Bull Head 3-Axis Servo Robotic Arm [https://www.zhiyirobotics.com/3-axis-silicone-servo-controlled-robotic-arm-for-injection-molding-machine-product/]. This report presents objective and detailed test data to help global injection molding enterprises, especially SMEs in Europe and America, make informed procurement decisions. All tested products have obtained ISO9001 and CE certifications, complying with international industrial standards.

Test Background & Scheme Design

1.1 Test PurposeAgainst the backdrop of the global injection molding industry's pursuit of "high efficiency, precision, and energy saving", this test aims to verify the core performance indicators of ZHIYI's 3-axis servo robotic arm in actual production scenarios, including load capacity, positioning accuracy, operation efficiency, and energy consumption. The test results provide data support for European and American buyers to evaluate the adaptability of the equipment to scenarios such as heavy-load mold picking, precision component production, and 24-hour continuous operation.

1.2 Test Object & Environment

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:

* 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 .
* 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.
* 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: plus-minus 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
plus-minus 0.1mm
99.9%
3C product connectors, auto sensor components

Traditional Pneumatic Manipulator
plus-minus 0.3mm
92%
Ordinary plastic parts, non-precision components

Hydraulic Manipulator
plus-minus 0.08mm
99.7%
High-precision molds, high cost

Test Analysis:

* The repeated positioning accuracy of ZHIYI's 3-axis servo manipulator reaches plus-minus 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.
* 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.
* 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 .
