Scraper merchant: Introduction to the performance of putty knife products
Scraper merchants; 1. The putty knife is made of stainless steel, which has a beautiful surface and good corrosion resistance. It is longer used than ordinary steel, and has high strength. Therefore, the possibility of using thin plates is high temperature oxidation resistance and high strength, which can resist fire. It is processed at room temperature and is very easy to plastic process, so there is no need for surface treatment.
Secondly, it has good elasticity, and the putty knife has excellent rebound performance, which will not deform after long-term use and is full of toughness.
3. The handle and body of the third putty knife are made of injection molding, which will not loosen after long-term use. At the same time, the surface of the putty knife produced by our company is high-precision polished, with a shiny and shiny appearance.
Scraper merchant: Mold design process for putty knife plastic handle
When designing the plastic handle mold for putty knives, it is necessary to determine the shrinkage rate of each part of the plastic based on experience, including the shrinkage range of the plastic, the wall thickness and shape of the plastic part, the size and distribution of the feeding port, and then calculate the cavity size. When it is difficult to control the shrinkage rate of high-precision plastic parts, the following methods should generally be used to design the mold:
1. Take a smaller shrinkage rate for the outer diameter of the plastic part and a larger shrinkage rate for the inner diameter to leave room for correction after mold testing.
2. Determine the form, size, and molding conditions of the pouring system through mold testing.
3. Determine the size changes of the plastic parts to be post-treated.
4. Correct the mold according to the actual shrinkage situation.
5. Try the mold again and adjust the process conditions slightly to adjust the shrinkage value to meet the requirements of the plastic part.
Scraper merchant: teach you how to use putty knives
Scraper merchants; When decorating houses, putty knives are often used, but many people do not know the correct way to use them
Putty knife, also known as steel scraper or shovel. It is composed of a handle and a thin steel plate. There are various specifications including 38mm, 50mm, 75mm, etc. Its characteristic is that the blade is thin and elastic, not easy to bend or deform, and is a commonly used tool for mixing putty, scraping putty, or cleaning putty scars, sand, and ash.
The grip method of the putty knife should be flexibly grasped according to the construction object, with the aim of powerful scraping, convenient operation, and leveling and filling. The grip method of the putty knife can be divided into direct grip and horizontal grip.
When holding directly, press the blade tightly with your index finger, and hold the handle with your thumb and other four fingers.
2. When holding horizontally, hold the scraper between your thumb and index finger close to the handle, and press the other three fingers on the blade plate. When mixing putty, use the putty knife alternately on both sides. When cleaning putty scars, hold the handle by hand.
It is worth noting that after using the putty knife, both sides of the blade should be wiped clean, a thin layer of butter should be applied, and the blade should be wrapped in paper for storage to avoid rusting when exposed to moisture.
The above is an introduction to the performance of putty knife products from scraper merchants. The putty knife is made of stainless steel, which has a beautiful surface and good corrosion resistance. It is longer used than ordinary steel, and has high strength. Therefore, the possibility of using thin plates is high temperature oxidation resistance and strength, which can resist fire. It is processed at room temperature and is easy to plastic process, so there is no need for surface treatment. I hope it will be helpful to you.
