Cleaning method of stamping parts with different materials
The cleaning of metal stamping parts is generally based on oil removal. Let's take a look at the stamping parts of different materials and the cleaning method of application.
1. Common cleaning problems of copper
The copper that can be processed can be divided into bronze, red copper, phosphorus copper, white copper, red copper, acid-free copper, beryllium copper, titanium copper, etc. Due to its electrical conductivity, thermal conductivity, wear resistance and plasticity, copper can be used in various mechanical processing.
The main products include terminals, reeds, radiator shells, bases, heat fins, bearings, guide sleeves, shells, conductive bars, flanges, instrument components, electrical elastic components, wear resistant parts and other products.
Copper is also a kind of mirror material, oily strong and easy to oxidize. It is easy to oxidize when cleaning or to form oil residue after drying.
Before choosing copper cleaning agent, the following issues should be considered:
01
Power of cleaning
The cleaning agent has better solubility, small surface tension and strong permeability, which is conducive to the cleaning effect of fine seam and blind hole of the workpiece.
02
volatility
Ensure that the liquid can be completely volatilized after cleaning copper processing workpiece without residue.
03
Corrosion and oxidation phenomena
It is required that the cleaning agent does not contain moisture, chlorine, sulfur and other corrosive substances, and will not corrode or oxidize various copper materials.
2. Common cleaning problems of aluminum
The density of aluminum is small, belongs to the light fog surface material, the main products can be processed are: digital products shell, power supply shell, mobile phone shell and so on.
Aluminum alloy is a material with fast thermal conductivity, good plasticity and easy oxidation.
The following issues should be considered before choosing aluminum cleaning agent:
01
Power of cleaning
Aluminum stamping processing is easy to heat, stamping processing oil will form stubborn oil marks on the surface, so the selection of cleaning agent cleaning ability is stronger, can clean all kinds of processing lubricating oil.
02
volatility
Ensure that the liquid can be completely volatilized after cleaning aluminum workpiece without residue.
03
Corrosion and oxidation phenomena
The cleaning agent has no corrosion or oxidation phenomenon on aluminum alloy stamping workpiece.
3, the common cleaning problems of stainless steel
Stainless steel as one of the most common metal stamping materials, the main processing products are: connector shell, terminal, spring, household kitchen, furniture hardware and other products.
Because stainless steel belongs to the surface roughness of the mirror material, and most of the sheet, easy to overlap together.
The following issues should be considered before choosing stainless steel cleaning agent:
01
Cleaning duration
Stainless steel stamping workpiece after cleaning, cleaning agent natural air drying or auxiliary drying time can not be too long.
02
Volatilization without residue
After drying, ensure that the stainless steel workpiece cleaning liquid can be completely volatilized without residue.
03
Cleaning time setting
Workpiece cleaning time setting, to ensure that the product clean surface will not be scratched.
