Hardware parts processing and regular maintenance of precision shaft parts processing play a vital role in the service life of the mold. Hardware parts exporter introduces you to some Tips for Hardware parts processing, which can be used by each mold user to ensure the effective operation of mold components such as hot runners, heaters, guide posts, ejectors, forming inserts, etc. to prevent unexpected situations.

Cross-check the resistance value of the heater. You should have measured the resistance of the heater when you first started using it, and it is time to measure and compare it again at the end of the year. If the resistance value fluctuates by ±10%, it is time to consider replacing the heater to ensure it does not fail at a critical point in the production process. If the initial resistance value has never been measured, measure it once and use the resulting value as a reference for future inspections of the heater.

Hardware parts processing, precision shaft parts processing Check for signs of wear between the guide post and guide bush. Look for signs of scratches or scuffs, which are mold-fitting wear due to lack of lubrication. If the marks are just emerging, you can also extend the life of the guide posts and guide bushes by lubricating them. If the wear is severe, it should be replaced with new parts. Otherwise, the cavity and core sections may not fit well, resulting in variable cavity wall thicknesses in the part.

Remember to remind the operator not to "clean" the hot tip at the gate. If the operator happens to see a small piece of stainless steel at the die-fitting nozzle, it may be a point nozzle assembly. "Cleaning up" this seemingly obstructive thing often destroys the hot tip. In order not to damage the hot nozzle, please confirm the nozzle type of the hot runner system before taking action, and ensure that all operators are trained to recognize the different types of nozzles they come into contact with.

At present, the commonly used optical parts processing technologies mainly include: CNC single-point diamond machining technology, CNC grinding and polishing technology, optical lens molding technology,optical plastic molding technology, magnetorheological polishing technology, electroforming technology and traditional grinding and polishing technology.

1. CNC single-point diamond machining technology

CNC single-point diamond machining technology is a processing technology for aspherical optical parts. It uses a natural single crystal diamond tool on an ultra-precision CNC lathe to process aspherical optical parts by single-point turning of the diamond tool under the precise control conditions of a specific processing environment. This technology is mainly used for optical parts of small and medium size infrared crystals and metal materials.

At present, the materials that can be directly processed to meet the optical surface quality requirements by diamond turning technology are mainly chromatic metals, germanium, plastics and infrared optical crystals. However, the processing of glass cannot meet the requirements of optical surface quality, and it is necessary to continue grinding and polishing correction. Another main use of CNC single-point diamond machining technology is to process various precision molds required for compression molding.

2. CNC grinding and polishing technology

CNC grinding and polishing technology is an optical part manufacturing technology that uses CNC precision machine tools to grind the surface of the workpiece into the required shape, and then polish it with a flexible polishing die to make the workpiece meet the technical requirements. The principle of this technology is closest to the classical optical processing technology, mainly through the digital precision control of the machine tool to achieve the precision processing of optical parts.

The main processing material of CNC grinding and polishing technology is glass, which makes up for the deficiency that CNC single-point diamond processing technology cannot directly process finished optical glass parts. This technology is mainly used to process spherical and aspherical optical parts. It is the main technology to replace the traditional classical method of optical glass processing. It has the advantages of high precision and high processing efficiency.

3. Optical lens molding technology

The optical lens molding technology is to put the softened glass into a high-precision mold, and directly press and mold the optical parts that meet the requirements of use under the conditions of heat, pressure and oxygen. It can be said that the popular application of optical lens molding technology is a major revolution in optical glass parts processing technology. This technology has epoch-making significance for the cost reduction and production increase of aspheric glass parts.
