  There are several coloring methods for   st ainless steel parts 1. Electroplating Electroplating: The process of attaching a metal film to the surface of metal or other materials by electrolysis. It can prevent corrosion, improve wear resistance, electrical conductivity, reflectivity and enhance aesthetics.   2. Water plating It does not rely on external power supply in the aqueous solution, but only relies on the reducing agent in the plating solution to carry out the chemical reduction reaction, so that the metal ions are continuously reduced on the autocatalytic surface to form a metal plating layer.   3. Fluorocarbon paint Refers to coatings with fluororesin as the main film-forming substance, also known as fluorocarbon paint, fluorocoating, and fluororesin coating.   4. Spray paint The paint is sprayed into a mist with compressed air and applied to the stainless steel plate to form different colors.   Additional ： The current color stainless steel pl...

  Polyformaldehyde (POM) thermoplastic crystalline polymer. Known as "Super Steel" or "Sai Steel", The English abbreviation is POM. Generally, polymers obtained by formaldehyde polymerization have a low degree of polymerization and are easily thermally depolymerized. It can be used as a raw material for organic chemicals and synthetic resins, and as a fumigant for drugs. 1.General property POM  is a hard, dense material with a smooth surface and gloss, light yellow or white, thin-walled partly translucent. Combustion characteristics are easy to burn, and continue to burn after leaving the ignition source. The flame is yellow at the upper end and blue at the lower end. Melting dripping occurs and has a strong pungent formaldehyde smell and fishy smell. POM is white powder, usually opaque, good coloring, specific gravity 1.41-1.43 g/cm3, molding shrinkage 1.2-3.0%, molding temperature 170-200℃, drying conditions 80-90℃ for 2 hours. POM's long-term heat resistance ...

Sandblasting is the process of cleaning and roughening the substrate surface by the impact of high-speed sand flow. Use compressed air as the power to form a high-speed jet beam to spray the blasting material (copper ore, quartz sand, corundum, iron sand, Hainan sand) at high speed on the surface of the workpiece to be processed, so that the appearance or shape of the outer surface of the workpiece surface changes. (1)  Workpiece coating and sandblasting before workpiece bonding can remove all dirt such as rust on the surface of the workpiece, and establish a very important basic pattern on the surface of the workpiece (the so-called rough surface). By changing the abrasives with different particle sizes, the roughness of different degrees is achieved, which greatly improves the binding force of the workpiece with coatings and plating materials. Or make the adhesive bond more firm and better quality. (2)  The rough surface of the casting, the cleaning and polishing of t...

Extrusion, also known as   extrusion molding   or extrusion, is also called extrusion in rubber processing. It refers to a processing method in which the material passes through the action between the barrel and the screw of the extruder, is plasticized while being pushed forward by the screw, and continuously passes through the machine head to make various cross-section products or semi-products. Injection molding is a method of producing shapes for industrial products. Products are usually injection molded from rubber and plastic. Injection molding can also be divided into injection molding and die casting. Injection molding machine, referred to as injection machine or injection molding machine, is the main molding equipment for making thermoplastic or thermosetting materials into plastic products of various shapes by using plastic molding die. Injection molding is realized by injection molding machine and mold.

Turn-Milling Compound Machining Center refers to the place where lathe and milling machine are processed together. It is an advanced cutting processing method that uses the combined motion of milling cutter rotation and workpiece rotation to realize the cutting processing of the workpiece, so that the workpiece can meet the requirements in terms of shape accuracy, position accuracy, and processed surface integrity. Compared with conventional CNC machining technology, the outstanding advantages of Turning-Milling-Compound-Machining-Center are mainly reflected in the following aspects: (1) Shorten the product manufacturing process chain and improve production efficiency. A variety of special tools and new tool arrangements can be installed to reduce tool change time and improve processing efficiency. Turning and milling composite processing can complete all or most of the processing operations in one clamping, thereby greatly shortening the product manufacturing proc...

What is 'Catch hook and thin-wall' of  plastic mold products ?​ 1. The Catch hook The catch surface and the amount of catch hook are the important basis for the test data during assembe.  Once made any tiny mistake about these numbers, It would become a huge mistake of the product. Therefore, during mould design, We needs to pay special attentin to the catch hook assembly and testing. 2. The thin-wall What is the big problem about thin wall? The binding point is particularly easy to press and brittle, Then could't pass the test. It will be difficult to assemble in the next step, The product will be uneven filling, shrink, and easy broken.

  The  plastic material  is a solid material which is based on a polymer and is added to the additive at a certain temperature and pressure, and is formed by solidification or cross-linking. Let us learn about the material of AS now. AS is a copolymer of acrylonitrile (A) and styrene (S). It has moderate weather resistance, is not affected by high humidity environment, and is resistant to general greases, detergents and mild alcohols. It has poor fatigue resistance and is not easy to be used. It can be cracked by stress, the material is highly transparent, and the fluidity is better than ABS. AS is suitable for the plastic products trays, cups, cutlery, toothbrushes, refrigerators, knobs, lighting accessories, accessories, instrument mirrors, boxes, stationery etc.
