Sandblasting is a general term used to describe the act of propelling very fine bits of material at high-velocity to clean or etch a surface. Sand used to be the most commonly used material, but since the lung disease silicosis is caused by extended inhalation of the dust created by sand, other materials are now used in its place. Any small, relatively uniform particles will work, such as steel grit, copper slag, walnut shells, powdered abrasives, even bits of coconut shell. Due to the dangers of inhaling dust during the process, sandblasting is carefully controlled, using an alternate air supply, protective wear, and proper ventilation.

There are hundreds of methods to make metal parts. The list of technologies and techniques can be overwhelming. To make matters worse, each approach technology comes with a variety of strengths and weaknesses. The purpose of this article is to give a quick overview of the predominant metal part fabrication techniques and discuss their strengths and weaknesses.

Die casting is a manufacturing process in which molten metal is poured or forced into steel molds. The molds—also known as tools or dies—are created using steel and are specially designed for each project. This allows each component to be created with accuracy and repeatability. Aluminum, zinc, and magnesium are the most commonly used die casting alloys

Metal stamping is a system of processes focusing on sheet metal manufacturing. This is one big chunk of the whole science & art of metalworking.

The different casting processes are based on the type of mould or the method used to fill the mould.

Coating is a thin layer of plastic coated on metal, fabric, plastic and other substrates for the purpose of protection, insulation and decoration. The rubber coating is one of the most widely used processes of coating in various applications. Such protective coating is applied onto or impregnated into a substrate or an object for protective, decorative or functional purposes. Rubber coating medium is a very important consideration in the selection of coating material. This type of coating is used on many die casting components like seals, gaskets, o-rings, stoppers and plungers, which are used in a variety of industrial applications like electronics, medical, automotive, military industries, etc. The method of plating a layer of nickel on metal or some nonmetal by electrolysis or chemical method is called nickel plating. Nickel can be divided into electroless nickel plating and electroless nickel plating.

Based on decades of experiences on mold making and metal die casting service, we know that aluminum polishing service is important to aluminum casting because the die casting products are often rough after the manufacturing and require surface treatment to get smoother edges, preciser measurements and better surface quality. Metal polishing services at diecasting-mould.com are our major finishing services to improve the exterior of your aluminum die castings and other alloy die cast parts. Polishing surface treatment can remove parting lines and overflows from the die casting process, and heat checking or die washout on old casting surfaces, as well as enhance the safe treatment and increase the aesthetics of die casting components. Accomplished team at Junying die casting plant will follow the safety guideline and industry practices to deliver high-quality polished castings. We can transform your design into a fully finished product all in-house.

Pad printing is one of the special printing methodsto transfer the color and image that you wanted on surfaces. The process of pad printing is the most versatile of all printing processes with its unique ability to images and text on to three-dimensional, complex surfaces. Using steel (or copper, thermoplastic plastic) gravure, using a curved surface pad printing head made of silicone rubber material, dip the ink on the gravure onto the surface of the pad printing head, and then press on the surface of the desired object to print patterns. For example, the text and patterns on the surface of mobile phones are printed in this way,and the surface printing of many electronic products, such as computer keyboards, instruments and meters, are all printed by pad printing. You can also choose pad printing method to print logo on your die casting parts. The theory behind the pad printing process evolved from the screen, rubber stamp and photogravure printing processes.

Silk-screen printing is one of the most popular printing techniques, and is the most-used by companies when printing images and designs onto products of different sizes and materials including T-shirts, paper, wood, ceramics, die casting parts and more. Screen printing refers to the use of silk screen as a plate base, and through the photosensitive plate making method, made into a screen printing plate with graphics and text. Screen printing consists of five elements: screen printing plate, scraper, ink, printing table and substrate. The basic principle of screen printing plate is that the mesh of picture and text can pass through the ink, and the mesh of non graphic part can not pass through the ink. During printing, the ink is poured into one end of the screen printing plate, and a scraper is used to exert a certain pressure on the ink position on the screen printing plate, and at the same time, the ink moves uniformly towards the other end of the screen printing plate. During the movement, the ink is squeezed onto the substrate from the mesh of the picture and text part by the scraper.
