Cold Forging

Ming Xiao as a metal parts manufacturer custom cold forging parts many years,we produce standard welding nuts,locking nuts with metric threads, and use cold forging process to produce rough parts for our turning parts and machining parts to save the material cost.

The cold forging process also known as cold heading, it’s one of the new processes for processing metal cutting without cutting. It is a method of processing the required parts or blanks by utilizing the plastic deformation of the metal under external force and by means of the mold to redistribute and transfer the metal volume. The cold heading process is best suited for the production of standard fasteners such as bolts, screws, nuts, rivets, pins.

The equipment commonly used in the cold heading process is a dedicated cold heading machine. If the production volume is not too large, it can also be replaced by a crank press or a friction press. With the rapid development of China’s national economy, the multi-station automatic cold heading machine designed and manufactured by the Chinese working class has reached the advanced level of specialization and high efficiency.

Stamping is the forming process of the workpiece (stamping part) by applying external force to the plate, strip, pipe and profile by press and die to produce plastic deformation or separation. Stamping and forging belong to forming processing (or pressure machining). The stamping materials are mainly hot rolled and cold-rolled steel plates and steel strips.

Stamping is the production technology of product parts with a certain shape, size and performance by using the power of conventional or special stamping equipment to make the sheet metal directly deformed and deformed in the mold. Sheet metal, mold and equipment are the three elements of stamping process. According to the stamping temperature, it can be divided into hot stamping and cold stamping. The former is suitable for sheet metal processing with high deformation resistance and poor plasticity, while the latter is carried out at room temperature, which is a common stamping method for thin plates. It is one of the main methods of metal plastic processing (or pressure machining), and also belongs to material forming engineering technology.

The die used for stamping is called stamping die, or die. Punching die is a special tool for batch processing material (metal or non-metal) into the required stamping parts. Punching die is very important in stamping. Without the punching die that meets the requirements, mass stamping is difficult to carry out. Without advanced die, the advanced stamping process can not be realized. Stamping process and die, stamping equipment and stamping materials constitute the three elements of stamping process, only if they combine each other to get stamping parts.

Stamping is mainly classified according to technology, which can be divided into two categories: separation process and forming process. The separation process, also known as blanking, aims at separating the stamping parts along the contour line and ensuring the quality requirements of the separation section. The purpose of forming process is to make the sheet metal plastic deformation without breaking the blank, and make the workpiece with the required shape and size. In actual production, many kinds of processes are usually applied to a workpiece. Blanking, bending, shearing, stretching, bulging, spinning and straightening are the main stamping processes.

Separation process

(blanking)

It is a basic stamping process using die separation material. It can be directly made into flat parts or for other stamping processes such as bending, drawing, forming and so on. It can also be cut and trimming on the formed stamping parts. Blanking is widely used in automotive, household electrical appliances, electronics, instrumentation, machinery, railway, communications, chemical industry, light industry, textile and aerospace and other industrial sectors. Punching process accounts for about 50% to 60% of the whole stamping process.

Forming process

Bending: plastic forming method for bending metal plates, fittings and profiles into a certain angle, curvature and shape. Bending is one of the main processes widely used in stamping parts production. The bending of metal material is essentially an elastic-plastic deformation process. After unloading, the workpiece will produce elastic recovery and deformation, which is called springback. Springback affects the accuracy of workpiece, which is the key technology that must be considered in the bending process.

Deep drawing: drawing, also known as drawing or calendering, is a stamping process using moulds to make flat billets into blanks after punching. The deep drawing process can be used to make cylindrical, stepped, tapered, spherical, box shaped and other irregular shaped thin-walled parts. If combined with other stamping processes, parts with extremely complex shapes can also be manufactured. In the stamping production, there are many kinds of drawing parts. Because of its different geometric features, the position of the deformation zone, the nature of the deformation, the distribution of the deformation, and the stress state and distribution of each part of the blank are quite, even the essential difference. Therefore, the determination of process parameters, procedure number and sequence, and the design principles and methods of mold design are different. According to the characteristics of deformation mechanics, all kinds of deep drawing parts can be divided into four types: straight wall rotary body (cylindrical part), straight wall non revolving body (box body), surface slewing body (surface shape part) and surface non revolving body.

The tensile force is applied to the sheet material by the drawing die to produce uneven tensile stress and tensile strain, and the bonding surface of the plate and the drawing die gradually expands until it is completely fitted to the drawing model. The main object of the drawing is the hyperbolic skin with a certain plastic, large surface area, smooth and smooth curvature, and high quality (accurate shape, smooth streamline and stable quality). Because the process equipment and equipment are relatively simple, the drawing cost is low and flexible, but the material utilization and productivity are low.

Spinning is a metal rotary processing technology. In the process of processing, the billets are actively rotated with the spinning die or spinning head around the billet and the spinning die actively, and the spinning head is fed by the core die and the blank. The blank revolving parts are obtained by the continuous partial deformation of the blank.

Plastic is the two trimming of the shape of the product using the shape of the tool. It is mainly reflected in the pressure plane, the bullet and so on. In view of the elasticity of some materials, it is impossible to guarantee the quality of the forming.

Bulging is the processing method of obtaining parts by using die to make sheet metal thinning and increasing surface area. It is commonly used in the form of undulation, bulging of cylindrical (or tubular) blanks and stretching of flat blanks. Bulging can be realized by different methods, such as bulging, rigid bulging and hydraulic bulging.

Flanging is a plastic processing method to bend the material in the narrow strip area of the edge of the blank or the edge of the blank on the curve or straight line. The flanging is mainly used to strengthen the edge of the parts, remove the cutting edges and make the parts assembled and connected with other parts on the parts or the three-dimensional parts with complex specific shape and reasonable space, and improve the stiffness of the parts. In large sheet metal forming, it can also be used as a means to control breakage or crease. So it is widely used in automobile, aviation, aerospace, electronics and household appliances.

Necking is a stamping method that reduces the diameter of the flanged hollow part or the open end diameter of the tube blank. The change of the end diameter of the workpiece before and after the necking should not be too large, otherwise the end material will wrinkle because of the severe compression deformation. Therefore, it is often necessary to shrink the necks from smaller diameters with larger diameters.

CNC Precision Turning

CNC lathe machining is a high-precision, high-efficiency machining method for controlling the displacement of parts and tooling with digital information for automated machine tools. It is an effective way to solve the problems of variety, small batch size, complex shape and high precision of aerospace product parts and realize high efficiency and automatic processing.

CNC lathes are one of the most widely used CNC machines. CNC lathes are mainly used for machining rotary parts such as shafts and discs. Through the operation of the NC machining program, the cutting process of the inner and outer cylindrical surface, the conical surface, the forming surface, the thread and the end surface can be automatically completed, and the work of the groove, the drilling, the reaming, the reaming, and the like can be performed. The turning center can complete more machining operations in one setup, improve machining accuracy and production efficiency, and is especially suitable for machining complex-shaped rotary parts. Some ordinary machine tools can not or inconveniently process parts, the processing quality is stable, and the labor intensity of workers is reduced.

Plastic Injection Molding

The process cycle for injection molding is very short, typically between 2 seconds and 2 minutes, and consists of the following four stages:

Clamping – Prior to the injection of the material into the mold, the two halves of the mold must first be securely closed by the clamping unit. Each half of the mold is attached to the injection molding machine and one half is allowed to slide. The hydraulically powered clamping unit pushes the mold halves together and exerts sufficient force to keep the mold securely closed while the material is injected. The time required to close and clamp the mold is dependent upon the machine – larger machines (those with greater clamping forces) will require more time. This time can be estimated from the dry cycle time of the machine.

Injection – The raw plastic material, usually in the form of pellets, is fed into the injection molding machine, and advanced towards the mold by the injection unit. During this process, the material is melted by heat and pressure. The molten plastic is then injected into the mold very quickly and the buildup of pressure packs and holds the material. The amount of material that is injected is referred to as the shot. The injection time is difficult to calculate accurately due to the complex and changing flow of the molten plastic into the mold. However, the injection time can be estimated by the shot volume, injection pressure, and injection power.

Cooling – The molten plastic that is inside the mold begins to cool as soon as it makes contact with the interior mold surfaces. As the plastic cools, it will solidify into the shape of the desired part. However, during cooling some shrinkage of the part may occur. The packing of material in the injection stage allows additional material to flow into the mold and reduce the amount of visible shrinkage. The mold can not be opened until the required cooling time has elapsed. The cooling time can be estimated from several thermodynamic properties of the plastic and the maximum wall thickness of the part.

Ejection – After sufficient time has passed, the cooled part may be ejected from the mold by the ejection system, which is attached to the rear half of the mold. When the mold is opened, a mechanism is used to push the part out of the mold. Force must be applied to eject the part because during cooling the part shrinks and adheres to the mold.

In order to facilitate the ejection of the part, a mold release agent can be sprayed onto the surfaces of the mold cavity prior to injection of the material. The time that is required to open the mold and eject the part can be estimated from the dry cycle time of the machine and should include time for the part to fall free of the mold. Once the part is ejected, the mold can be clamped shut for the next shot to be injected. After the injection molding cycle, some post processing is typically required. During cooling, the material in the channels of the mold will solidify attached to the part. This excess material, along with any flash that has occurred, must be trimmed from the part, typically by using cutters. For some types of material, such as thermoplastics, the scrap material that results from this trimming can be recycled by being placed into a plastic grinder, also called regrind machines or granulators, which regrinds the scrap material into pellets. Due to some degradation of the material properties, the regrind must be mixed with raw material in the proper regrind ratio to be reused in the injection molding process. Injection molding is the most commonly used manufacturing process for the fabrication of plastic parts.

A wide variety of products are manufactured using injection molding, which vary greatly in their size, complexity, and application. The injection molding process requires the use of an injection molding machine, raw plastic material, and a mold. The plastic is melted in the injection molding machine and then injected into the mold, where it cools and solidifies into the final part. The steps in this process are described in greater detail in the next section. Injection molding is used to produce thin-walled plastic parts for a wide variety of applications, one of the most common being plastic housings. Plastic housing is a thin-walled enclosure, often requiring many ribs and bosses on the interior. These housings are used in a variety of products including household appliances, consumer electronics, power tools, and as automotive dashboards. Other common thin-walled products include different types of open containers, such as buckets. Injection molding is also used to produce several everyday items such as toothbrushes or small plastic toys. Many medical devices, including valves and syringes, are manufactured using injection molding as well.
