Precision pumping machine reduce product defects

Fine pumping machines can reduce product defects by:

1. Optimize mold design and maintenance

High-precision mold design: The dimensional accuracy and shape accuracy of the mold directly affect the product quality. When designing the mold, the tolerance of key parameters such as the inner diameter, outer diameter, and taper must be strictly controlled within a very small range to ensure that it is highly matched with the target size and shape of the product. For example, for high-precision pipe drawing, the concentricity of the mold must reach an extremely high level to prevent uneven wall thickness of the pipe.

Mold material selection: Choose high-quality mold materials, such as alloy steel or cemented carbide with high hardness, high toughness and strong wear resistance. These materials can keep the shape of the mold stable during the long-term fine drawing process, and reduce defects such as product surface scratches and dimensional deviations caused by mold wear.

Mold maintenance and replacement: Establish a regular mold inspection and maintenance system. Clean up impurities and debris in the mold in a timely manner, and check the wear of the mold. When the mold wear exceeds a certain limit, replace the mold in time to avoid product defects caused by mold aging.

2. Precisely control processing parameters

Speed control: The drawing speed of the fine drawing machine must be precisely adjusted. Too fast speed may lead to rough product surface and out-of-tolerance size, while too slow speed will affect production efficiency. Determine the best drawing speed based on the hardness, toughness and product specifications of the material, and use an advanced speed control system to ensure speed stability and reduce product defects caused by speed fluctuations.

Tension control: Appropriate tension is the key to ensuring product quality. The tension during processing is monitored in real time by a tension sensor, and the tension is stabilized at the set value by a feedback control system. Improper tension can cause problems such as stretch marks and deformation on the product. Accurate tension control can effectively avoid these defects.

3. Perfect detection and feedback mechanism

Online testing equipment: Install online testing instruments, such as high-precision laser diameter gauges, profile scanners, etc. These devices can measure the size, shape, surface quality and other parameters of the product in real time, and detect whether the product has defects in time.

Feedback adjustment: The detection data is fed back to the control system in real time. Once a product defect is found, the control system quickly adjusts the processing parameters of the fine drawing machine, such as adjusting the mold position, correcting the speed and tension, etc., to correct the defect in time and prevent the production of more defective products.
