Tungsten steel needle can according to the different requirements of products, making the different shapes of blunt needle, mass of the hole processing, for example, computer chassis, above will have a lot of cooling hole, there are many mobile phones, electrical appliances, machinery is used above, and with the ordinary drilling machine, or cars, milling machine, can only work out round hole, and the efficiency is quite low.In the case of stamping, it takes less than a second to process hundreds of holes at the same time, which greatly improves production efficiency. 1. Characteristics of tungsten steel punching needle High hardness (hardness HRC90), batch punching, improve production efficiency.Tungsten steel punching needle is used for punching, can be used for various types, shaped holes. 2. Selection of tungsten steel punching needle material According to the material and thickness of stamping, different tungsten steel should be selected. In general, the thicker the stamping product, the better the lower hardness of tungsten steel.The harder the material is, the harder the tungsten steel is to choose a slightly less rigid model so that it can be effectively avoided.And the sheet that presses relatively thin, or the hardness is not high, this kind of product's hole processing, tungsten steel blunt needle can use hardness taller a few, this can increase the service life of the punching needle. 3. Type of punch punch According to the material of different can be divided into SKD blunt needle, needle SKH blunt blunt needle, needle and ASP SKD blunt needle is made of blunt needle use SKD special mold steel, according to the needs of production physical can have a variety of different shapes.SKH, ASP blunt blunt needle and the high speed steel, tungsten steel needle is different because the material, the appearance is different,

Metal stamping die structure can be divided into upper and lower mold.The upper mold is made up of die handle (punch), guide sleeve, punch, pad, fixed plate, screw, pin, upper die (upper), and release plate.The lower mould is usually composed of the lower mould base, the guide plate (side guide plate), the concave mould, the baffle plate, the bearing plate, the guide post, the screw and the pin. It is important to note that not all of the stamping die structures have the above six parts, especially the single process module, but the working parts and necessary fixed parts are indispensable. Stamping die are usually divided into two categories, one kind is craft parts, the parts directly involved in the process is completed, and have the direct contact and blank, only for mold complete process is not directly involved in the process, also direct contact with blank, only to ensure that do use mould to complete the process, or to improve the mold function, including guide parts and fastening parts, standard parts and other parts, etc. NITONI, As a China Precision Mold parts, Core pin, Ejector pin, Mold punch, Mold parts, Mold components, Non-standard Precision Parts, plastic mold parts, press die mold parts, manufactur and supplier,At present, The mould accessories products are mainly divided into Non-standard mold parts, Plastic mould parts, Press die mold parts, Die Springs,

Plastic mold design is based on the correct design of plastic products, and mold design and manufacturing are closely related to plastic processing.The success or failure of plastic processing depends greatly on the mold design effect and the mold manufacturing quality. Then, what structural factors should be considered in the design of plastic mold? 1. Parting surface The contact surface of the die and the punch when the die is closed.Its position and form are selected, affected by product shape and appearance, wall thickness, molding method, post-processing technology, mold type and structure, demodulation method and molding machine structure, etc. 2. Structural parts That is, the slide block of the complex mould, the inclined top, the straight top block and so on.Structure design is critical, is related to the life of the mold, the processing cycle, cost, quality, etc., so the design of complex mold core structure on the designer's comprehensive ability the demand is higher, as far as possible the pursuit of more simple, more durable and more economical design. 3. Mold precision Namely avoid card, precise position, guide pillar, position pin and so on.Positioning system is related to the appearance quality of the products, mold quality and life expectancy, according to the mould structure is different, choose different way of positioning, rely mainly on machining precision control, internal model is mainly targeted at the designer to consider fully, to design more reasonable and easy to adjust positioning way.

As precision plastic, stamping mould processing manufacturers, often need to purchase the corresponding mold parts, among them, the quality of die parts directly determine its service life, therefore, a lot of plastic, stamping mold processing plant more and more pay attention to the durability of the mould parts.As you know, everything needs to be repaired and maintained in the process of use. Next, we will share the details of the maintenance of spare parts for injection molding and stamping die processing factory. In the process of the use of the mould, it is necessary to continuously inspect and repair the mold. Of course, the preventive measures should also be carried out, and the regular maintenance of the mold parts will play a crucial role in the service life of the molds.The annual maintenance procedure required for each injection molding position depends on the different mould cycle, how to repair the mold parts and so on. 1. Check whether there is an early warning of rust or moisture in the loose hole. If you find rust or humidity near the vent hole, it means that the internal condensation, or the water pipe, may break.Moisture can cause a fatal short-circuit to the heater.If the machine is not running all year round and needs to be shut down at night or on weekends, the chances of this condensation occur. 2. Chec

The stamping die will wear out frequently during the production process, which is the most considered problem for many metal stamping die manufacturers and stamping die users.So how to improve the durability of stamping die from structural design and material selection?As the manufacturer of mold parts, changsha borun thinks: Stamping die is a necessary process equipment in stamping process, which is decisive to improve product quality, prolong product life and improve production efficiency.However, due to the constant wear and tear of the stamping die in the production process, it is difficult to meet the production demand.Therefore, it is very important to improve the durability of the stamping die.Here are some ways to improve the durability of the stamping tool. 1. Improve the design of stamping die. Whether the stamping die design is reasonable is the foundation for improving the durability of the stamping die.To design a stamping die as a result, the adverse conditions to take effective measures in response to the product forming, in order to improve the durability of progressive metal stamping tools, such as the life of the stamping die design holes tend to show on the rush hole punch.For this type of stamping die, it should be designed to shorten the length of the small punch to increase the strength. Meanwhile, the guide sleeve should be adopted to strengthen the small convex mould for protection.In addition, in stamping die design, it is necessary to take full account of the form of the formwork, the fixed method and orientation of the convex and concave modes, the determination of the p

This article is from NITONI changsha borun Original address:https://www.borunmould.com/Article/howtoimprov.html Die non-standard parts manufacturers can process which parts?In fact, for the mold parts industry standard parts and non-standard parts, a large number of people are confused!So, to borrow this opportunity, changsha borun is simply to say the non-standard parts of plastic and stamping parts: 1. injection molding, plastic non-standard parts The parts of the injection mold and the product glue position are usually non-standard parts, the main ones are the front die, the rear die and the inserts.It can also be said that other than screws, water bill, thimble, rubber ring, spring, the rest of the mold is not a standard. 2. Non-standard parts for stamping die design The spare parts on the stamping die can be designed as non-standard, but for convenience and economy, the concave mould must be non-standard.The rest is determined according to the situation. Generally, the mould frame, guide column and guide sleeve are all standard, and the others can be determined according to the situation.As for these, we can check the general stamping manual, and the attached pages usually have standard parts. NITONI, As a China Precision Mold parts, Core pin, Ejector pin, Mold punch, Mold parts, Mold components, Non-standard Precision Parts, plastic mold parts, press die mold parts, manuf

Industrial production to injection molding, blow molding, extrusion, die casting or forging molding, smelting, the methods of stamping products of various molds and tools needed for call mould, with the development of the industry, aviation, hardware, automotive, home appliances, medical, articles for daily use, such as manufacturing production is inseparable from the mold. Die spare parts refer to the general name of metal parts used for stamping die, plastic mold or FA automation equipment.Mould parts are widely used in various kinds of plastic mould, stamping die, automobile, electric and aviation. According to the mold industry, it is divided into standard parts and non-standard parts: 1. Mold standard parts. National standard, Japan MISUMI/O standard, us DME/O standard, Spanish CUMSA/O standard, German HASCO/O standard, Germany FIBRO standard, etc. Standard parts of the mold is standard, which is standardized without special and popular.Standard parts can also be fine for plastic mold parts and metal stamping die accessories and automatic machinery parts.

Today, with the booming manufacturing industry, the prospect of precision mold design and manufacturing industry is rising, and the competition among mold manufacturing companies is becoming increasingly fierce.Enterprise survival of the fittest, as the basic law of survival in the market, is not a single dependence on one aspect, more is the measurement of the mold manufacturing company's comprehensive strength.Here, changsha borun talks about the technical requirements of the top needle manufacturers: The plastic mold needs a thimble to fit the work.Because of the high precision and high strength of the thimble, the quality of the thimble is gradually obtained by the majority of recognition, and the processing technology good thimble can play a key role in the mould.And the high quality thimble is inseparable from the three technology support. 1. Electric spark milling technology. Because the edm milling process has the characteristics of the intelligent and automation, so can make full use of high speed rotating a way to make a multi-dimensional three-dimensional products, high precision thimble division tube is in the technology does not need to adopt under the condition of complex electrical circuits. 2. Mould software technology.

Speaking of the thimble, I believe everyone will be familiar with it.Thimble is one of the most widely used mould parts.It can be used to separate the workpiece, also can be used in the mold, the fixed function. Since contact mold accessories industry, there are a number of the processing and wholesale mould thimble to clients concerned with mould thimble specifications, such as domestic thimble specifications, HASCO standard thimble specifications, DME standard thimble specifications and so on.In view of this, the thimble manufacturer changsha borun according to the above mold thimble specification, combined with the production practice of the company, sorted out the mold thimble relevant specifications, have the custom requirement friend to know! Standard thimble relative to the non-standard thimble production cycle shorter, fitment is higher, because of its features can be mass production, so the cost is relatively lower, while the standard thimble can't replace all of the injection mould thimble, but also very widely used.

In 2018, it has been quietly arrived, looking back on the road of the mold parts industry, and it has been 10 years.In this decade, the borun embellish people always adhere to the "don't forget to beginner's mind, party always" concept of development, guided by the demands of market and industry, with constant innovation, strive to improve the product quality as the vitality of enterprise development, adhere to the people-oriented, advancing with The Times, scientific management, constantly sending qualified mould parts products to industry market. On February 3, 2018, for all the borun embellish people, is a day of celebration, enterprise's annual convention in under the common aspirations of all pulled open heavy curtain, the enterprise annual meeting, no matter from theme planning, activity plan, arranging the site, are carefully arranged.The whole activity has arranged a variety of programs, such as dance, choral songs, poetry recitation, etc., and everyone has participated actively, showing the versatile side.

Friends who touch the mold industry know that SKD61 thiming and SKH51 are used more in plastic mold.When the client is consulting or ordering a thimble, many times will ask about the hardness, wear resistance and durability of the die thimble.Mold parts manufacturers of changsha borun embellish think actually, plunger wear resistance and durability are not completely depend on the material hardness, but different material has its own scientific and reasonable hardness. SKD61 thimble, for example, air cooling quenching, quenching temperature 1020-1020 degrees, the surface hardness above HV900 (HRC60-67 degrees), and the use of 60-62 HRC hardness, heat treatment deformation is small, can be nitriding surface nitriding processing, processing of the product has better wear resistance.With high technology polishing technology, it can reduce the surface friction coefficient, enhance the wear resistance and corrosion resistance, and ensure the use of the mold more than a million times.Internal tempering hardness hrc40-45 degree, after secondary tempering, SKD61 thimble and high toughness, high heat resistance using temperature up to 550 degrees, suitable for high temperature mold long use. It is not difficult to see that when the thimble is processed in the mold, each material or each mold accessory has a suitable hardness in the application.Only when the appropriate hardness is selected, and the relevant technical treatment, the thimble in the mold will achieve the desired effect, and the wearability and durability will naturally improve.
