II. Product Features
1. Ergonomic design, comfortable and efficient operation
The handle shape is designed according to the structure of the human palm, and the surface is treated with anti-slip texture or soft rubber wrapping, which fits the curve of the hand and is not easy to fatigue after long-term operation. Some models are equipped with shock-absorbing devices, which can effectively alleviate the vibration feedback during operation, improve the operating comfort by 40%, and improve the operating efficiency by 30%.
2. High-strength material, strong durability
Engineering plastics: PA66+GF30 and other reinforced engineering plastics are selected, which have high strength, high toughness, wear resistance, chemical corrosion resistance, and are suitable for general industrial environments.
Alloy steel/aluminum alloy: 42CrMo alloy steel or 6061 aluminum alloy is used. After heat treatment, the strength is higher and it can withstand greater external forces. It is suitable for heavy loads and harsh working conditions, and the service life is up to 5-8 years.
3. Diversified functional design, wide adaptation
It provides a variety of types such as button type, rocker type, knob type, etc., integrating emergency stop switches, function buttons, indicator lights and other components to meet the operation needs of different equipment. Supports customized function configuration, can add sensors, communication modules, etc. according to customer requirements, and adapt to various types of automation equipment.
4. High-precision manufacturing, stable performance

Adopting CNC machining and precision injection molding technology, the dimensional accuracy is controlled within ±0.1mm, and the parts fit tightly. After more than 100,000 operation life tests, the buttons are responsive and the structure is stable. It can still work stably in a temperature environment of -20℃ - 80℃. Some common specifications are as follows:

Type	Material	Applicable scenarios	Main functions
Button handle	Engineering plastic	Automated production line start and stop control	One-button start and stop
Joystick handle	Aluminum alloy	Industrial robot direction adjustment	Multi-axis linkage control
Knob handle	Alloy steel	CNC machine tool parameter adjustment	Precise knob control

III. Product Details
1. Material Type
Engineering Plastics: PA66+GF30 reinforced nylon has excellent mechanical properties and chemical resistance. By adding glass fiber reinforcement materials, the hardness and wear resistance are improved. It is often used in general industrial scenarios that are sensitive to weight and cost.
Alloy Steel: After quenching and tempering, 42CrMo alloy steel has high strength and good toughness. It can withstand large torque and impact force, and is suitable for the operating handle of heavy machinery and equipment.
Aluminum Alloy: 6061 aluminum alloy is light in weight and has good heat dissipation. After anodizing, it has good wear resistance and corrosion resistance. It is suitable for equipment that requires portability and aesthetics.
2. Structural Design
Handle Structure: Streamlined design, non-slip texture or soft rubber layer on the surface to increase friction, some models have built-in shock-absorbing rubber to reduce the transmission of operating vibration.
Functional Components: Integrated micro switches, potentiometers, encoders and other electronic components to achieve accurate signal feedback; the emergency stop button adopts a red mushroom head design, which meets safety standards and is convenient for quick operation in emergency situations.
Connection method: Provide threaded connection, flange connection, snap connection and other methods to facilitate installation and fixation with the main body of the equipment, ensuring that the connection is stable and not loose.
3. Manufacturing process
Injection molding: Use high-precision injection molds and servo injection molding machines to ensure that the handle has a delicate appearance, precise dimensions, and a smooth surface without burrs.
CNC machining: For metal handles, complex structural shapes and high-precision installation holes are processed through CNC turning, milling, grinding and other processes.
Surface treatment: Engineering plastic handles can be painted and silk-screened; metal handles provide surface treatment processes such as anodizing, nickel plating, and chrome plating to improve aesthetics and protective performance.
4. Quality inspection
Appearance inspection: Use visual inspection equipment to check whether there are scratches, bubbles, color differences and other defects on the surface of the handle to ensure the appearance quality.
Functional inspection: Use automated testing equipment to test the buttons, knobs, rockers and other functions of the handle to verify the accuracy and stability of the signal output.
Durability test: Conduct key life test (≥100,000 times), tension test, salt spray test (≥48 hours), etc. to ensure that the product can operate reliably under various working conditions.
