Track bolt surface treatment method

 

1. Plating of track bolts

  

The plating of track bolts refers to immersing the parts to be electroplated in a specific aqueous solution. The aqueous solution will contain some deposited metal compounds. After the current passes through the aqueous solution, the metal substances in the solution will precipitate and adhere to On the immersion part of the firmware. The plating of track bolts generally includes galvanizing, copper, nickel, chromium, copper-nickel alloy, and so on.

  

2. Hot-dip galvanized track bolts

  

Hot-dip galvanizing of fasteners is to immerse blown abrasive fasteners made of carbon steel into a plating bath of molten zinc with a heat of about 510 ° C, so that the iron-zinc alloy on the surface of the fasteners will become blunt. Zinc, thus obtaining a surface treatment effect. The price of hot-dip galvanizing of track bolts is higher than that of electroplating, which is about 1.5 to 2 yuan per kilogram.

  

3. Mechanical plating of track bolts

  

Mechanical plating of track bolts refers to the impact of the surface of the track bolts with powder of coated metal by specific physical and chemical means, so that the plated metal forms a coating on the surface of the fastener by cold welding to achieve the surface treatment effect . Mechanical plating of track bolts is mainly suitable for spare parts such as screws, nuts and washers.

Factors affecting the quality of track bolts

 

1. The influence of molding material and molding process on the size of track bolts.

 

The dimensional deviation of the investment mold is mainly caused by the instability of the molding process, such as the clamping force, the wax pressing temperature (the higher the wax pressing temperature, the greater the shrinkage rate of the investment line), and the injection pressure (the larger the injection pressure, The smaller the linear shrinkage rate of the investment mold), the holding time (the longer the holding time, the smaller the shrinkage), the molding temperature (the higher the molding temperature, the greater the linear shrinkage), the mold opening time, cooling method, room temperature, etc. Factor fluctuations cause deviations in the investment size.

  

2. The influence of shell material and technology on the size of track bolts

  

The thermal expansion of the shell affects the size of the track bolts. The thermal expansion of the shell is related to the shell material and process.

  

3. the impact of pouring conditions on the size of the track bolts.

  

The temperature of the shell during pouring, the temperature of the molten metal pouring, the position of the track bolts in the shell, etc. will affect the size of the track bolts. In order to prevent the excessive size of the track bolts, we should pay attention to many factors that affect the accuracy of the size of the track bolts, strictly control the quality of raw materials and technology to stabilize the size of the track bolts.
