The quality of melamine tableware is closely related to the following key process points of melamine tableware. 1. Raw material ratio and ball mill fineness control The molding of melamine plastic tableware is a physical and chemical change process. From the description of the molding process, it can be known that the quality and weight of raw materials have an important impact on the quality of products. If the resin content in the raw materials is not enough, or the degree of ball milling of the raw materials is not enough, the raw materials are relatively rough, and the amount of raw materials added is insufficient, the structure of the produced tableware will be relatively loose or there will be obvious defects, and the soy sauce and vinegar in daily life will easily penetrate and hard to remove. 2. Surface printing ink quality control Since the surface printing ink in the tableware can directly contact the food, the ink that meets the hygiene and safety standards should be selected. 3. Pressing temperature, pressure, and curing time The cross-linking and curing of melamine-formaldehyde resin is a physical and chemical change process, so certain reaction conditions, such as temperature, pressure, and time, need to be guaranteed. The pressure-holding curing time depends on the thickness, type, molding pressure, temperature, etc. of the product. Too long or too short pressure-holding curing time will be detrimental to the performance of the product. 4. Mold finish and exhaust control The surface finish of the pressed product depends on the rationality of the raw material formula, and the finish of the mold itself is an important factor. Therefore, the finish of the purchased or manufactured mold should be strictly tested and accepted. If the exhaust is improper, pores will be formed on the surface of the tableware, which will deposit dirt and affect the hygiene of the tableware. After knowing the importance of these key processes, tableware manufacturers will have more knowledge of melamine raw material, melamine compression moulds or the pressing machine for melamine crockery. If you have your own quality brand and are committed to the production of high-quality melamine tableware, it is very helpful to find a supplier who values quality as much as you. Shunhao Machines and Moulds Factory could be your trusted partner, he can help you develop your business, not only provide you with quality products but also experienced service in the melamine tableware production industry.

First, let’s introduce the application of the high-frequency preheater, the preheating effect before forming, and then introduce the types. Generally, thermosetting molding materials, such as phenolic resin, urea plastic, melamine, epoxy resin are preheated by high-frequency preheating machine. Application: widely used in the molding industry, such as semiconductor discrete electronic components, integrated circuits, other microelectronic packaging, motor commutators, melamine (melamine) melamine tableware, plastic appliances, etc. Function: The molding compound heated by the high-frequency preheating machine can enhance the fluidity, shorten the die casting time, eliminate the internal stress of the material, eliminate the product water mark and improve the finish of the finished product, save the material consumption, and extend the life of the mold. Preheat and soften the molding compound powder (cake) before electronic components and electrical molding to improve product quality, insulation performance and mechanical properties. 10KW PREHEATER                                                               5KW PREHEATER The selection of different types of high-frequency preheater. 1. Choose the electrode form of the heating equipment according to the shape of the thermosetting molding compound: The form of the heating electrode of high-frequency preheater: Flat electrode type Roller type (roller electrode type, turntable electrode type) 2. According to the selection of the heating material to the electrode form Flat electrode type: most suitable for pre-forming heating of powder, granular materials, non-standard cakes, etc. Roller electrode type: most suitable for heating the cylindrical cake before preheating and forming. Rotary plate electrode type: powder and granular state can also choose the rotary plate electrode type (the molding compound does not need to be pre-shaped to achieve the preheating effect of the roller electrode). Shunhao Factory melamine preheater machine is the flat electrode type. It’s mostly used for melamine moulding compound preheating process before molding by hydraulic compression machine. For the different models of preheating machine in Shunhao Factory, we have suggestions for you to follow: 3KW is very small, rarely used in the melamine industry 5KW is used normally, to work with 150tons-250tons machine, powder capacity u to 1000grams 7KW is similar to 5KW model, but its capacity is bigger, powder capacity upto 1200grams 10KW is most used for big pressure of melamine compression machine, from 300tons -800tons, powder capacity upto 6000 grams For urea toilet seat cover making machine,10 kw preheating machine is recommended

With the progress of technology, a new type of material, urea toilet seat and cover is more and more popular.  It almost replaces the old PP material for its unique features. Let’s get to know more about these two kinds of material. PP is a semi-crystalline material; it is harder than PE and has a higher melting point. The ordinary plastic of PP cover plate is bright and flexible through hot melt forming, but it is easy to change color over time. Urea-formaldehyde is generally a water-soluble resin, which is easy to cure. The cured resin is non-toxic, colorless, and has good light resistance. It does not change color after long-term use. It does not change color during thermoforming. Various colorants can be added to prepare various bright colors products. The difference between urea-formaldehyde toilet seat and PP toilet seat 1. The urea toilet seat cover is made from urea powder through high temperature and high pressure by UF toilet seat and cover making machine to mold into shape. It has porcelain-like surface, very good scratch resistance and stable color. 2. The ordinary plastic of the PP toilet cover is formed by hot melt. It has bright surface but easy to change color after a long time of use. 3. On the whole, the urea-formaldehyde toilet cover is beautiful in color and not easy to change color, which is more popular with consumers. Shunhao Factory not only produces Urea toilet seat and cover making machine but also the matched UF toilet lid moulds. If you have any needs, please feel free to contact us. Maybe you need some support for melamine molding equipment, you can also contact us.

Die steel is used to make cold die, hot forging die and die casting die steel. Moulds are the main processing tools for manufacturing parts in machinery manufacturing, radio instruments, motors, electrical appliances and other industrial sectors. The quality of the mold directly affects the quality of the pressure processing technology, the accuracy of the product, and the production cost. The quality and service life of the mold is mainly affected by the mold material and heat treatment in addition to the reasonable structure design and processing accuracy. Die steel can be roughly divided into (cold work die steel), (hot work die steel) and (plastic die steel) 3 types, used for forging, stamping, cutting, die casting, etc. Due to the different purposes of various molds and complex working conditions, the steel used for molds should have high hardness, strength, wear resistance, sufficient toughness, and high hardenability and other technological properties according to the working conditions of the mold made by it. 1. Cold work dies include cold punching dies, wire drawing dies, drawing dies, stamping dies, thread rolling dies, thread rolling plates, cold forging dies and cold extrusion dies. Cold work die steel should have high hardness, strength, wear resistance, sufficient toughness, and high hardenability and other process properties according to the working conditions of its manufacture. Commonly used steels include high carbon low alloy steel, high carbon high chromium steel, chromium molybdenum steel, medium carbon chromium tungsten steel, etc. 2. Hot work die is divided into hammer forging, die forging, extrusion and die casting, including hot forging die, press forging die, stamping die, hot extrusion die and metal die-casting die. In addition to being subjected to huge mechanical stress during work, thermally deformed moulds must also be subjected to repeated heating and cooling, which causes great thermal stress. In addition to high hardness, strength, red hardness, wear resistance and toughness, hot work die steel should also have good high temperature strength, thermal fatigue stability, thermal conductivity and corrosion resistance. In addition, it also requires high hardenability to ensure consistent mechanical properties throughout the section. For die-casting die steel, it should also have the surface layer to withstand repeated heating and cooling without cracks, and withstand the impact and erosion of the liquid die steel metal flow. Commonly used steels include chromium-manganese steel, chromium-nickel steel, chromium-tungsten steel, etc. Under normal circumstances, hot work die steel can be selected for injection molding or extrusion molding die. Cold work die steel can be used for thermoset molding and molds that require high wear resistance and high strength. 3. Plastic molds include thermoplastic molds and thermoset plastic molds. Plastic mold steel requires certain strength, hardness, wear resistance, thermal stability ...

Plastic molds are tools that are matched with plastic molding machines in the plastics processing industry to give plastic products a complete configuration and precise dimensions. According to the different molding methods, it can be divided into 6 types of molds. 1. Injection Mold Equipment: injection molding machine It is mainly a molding die that is most commonly used in the production of thermoplastic parts. Principle: The plastic is heated and melted in the heating barrel at the bottom of the injection molding machine, and then driven by the screw or plunger of the injection molding machine, it enters the mold cavity through the injection molding machine nozzle and the casting system of the mold, and the plastic is cooled and hardened to form, and the product is demolded . Application: Plastic products produced by injection molding process are very extensive, from daily necessities to various complex electrical appliances, auto parts, etc., are molded by injection molds. It is the most widely used processing method in the production of plastic products. 2. Blow Mold Equipment: Plastic blow molding machine A mold used to form hollow plastic containers (such as beverage bottles, daily chemical products and other packaging containers). Classification: According to the process principle, the forms of blow molding mainly include extrusion blow molding, hollow molding, injection blow molding, hollow molding (commonly known as injection stretch blow), multi-layer blow molding, hollow molding, and sheet blow molding etc. Application: Blow molding is only suitable for the production of thermoplastic products. 3. Extrusion Die Equipment: plastic extruder A type of mold used to mold and produce continuous-shaped plastic products, also called extrusion molding heads Application: Widely used in the processing of pipes, bars, monofilaments, plates, films, wire and cable coatings, profiled materials, etc. Principle: The solid plastic is melted and plasticized under the conditions of heating and the screw rotation and pressure of the extruder, and a continuous plastic product with the same cross-section as the die shape is made through a specific shape of the die. Its manufacturing materials mainly include carbon structural steel, alloy tools, etc. Some extrusion dies will also be inlaid with wear-resistant materials such as diamond on the parts that need wear-resistant. 4. Blister Mold A mold that uses plastic plates and sheets as raw materials to form some simpler plastic products. Principle: The plastic plate or sheet fixed on the concave mold or the convex mold is deformed under the condition of heating and softening by using the vacuum blooming method or the compressed air molding method to stick to the cavity of the mold to obtain the desired molded product. Application: Mainly used in the production of packaging products such as daily necessities, food and toys. Due to the low pressure during forming, the blister mold is made of cast aluminum or non...
