Injection molding is a manufacturing process for producing parts from thermoplastic or thermoset plastic materials. The process begins with heating the material to a molten state then forcing it into a shaped cavity. Injection molding is used to make various parts, including small disposable items and large & complex components. The main advantages of injection molding are its ability to produce large quantities of parts quickly and accurately. In addition, its ability to create complex shapes that would be difficult or impossible to make with other manufacturing processes sets it apart from the rest.
Injection moulding (injection molding) is a manufacturing process for producing parts by injecting molten material into a mould, or mold. Injection moulding can be performed with a host of materials mainly including metals (for which the process is called die-casting), glasses, elastomers, confections, and most commonly thermoplastic and thermosetting polymers. Material for the part is fed into a heated barrel, mixed (using a helical screw), and injected into a mould cavity, where it cools and hardens to the configuration of the cavity. After a product is designed, usually by an industrial designer or an engineer, moulds are made by a mould-maker (or toolmaker) from metal, usually either steel or aluminium, and precision-machined to form the features of the desired part. Injection moulding is widely used for manufacturing a variety of parts, from the smallest components to entire body panels of cars.
Injection moulding uses a special-purpose machine that has three parts: the injection unit, the mould and the clamp. Parts to be injection-moulded must be very carefully designed to facilitate the moulding process; the material used for the part, the desired shape and features of the part, the material of the mould, and the properties of the moulding machine must all be taken into account. The versatility of injection moulding is facilitated by this breadth of design considerations and possibilities.
Normally, the plastic materials are formed in the shape of pellets or granules and sent from the raw material manufacturers in paper bags. With injection moulding, pre-dried granular plastic is fed by a forced ram from a hopper into a heated barrel. As the granules are slowly moved forward by a screw-type plunger, the plastic is forced into a heated chamber, where it is melted. As the plunger advances, the melted plastic is forced through a nozzle that rests against the mould, allowing it to enter the mould cavity through a gate and runner system. The mould remains cold so the plastic solidifies almost as soon as the mould is filled.
Injection moulding is used to create many things such as wire spools, packaging, bottle caps, automotive parts and components, toys, pocket combs, some musical instruments, one-piece chairs and small tables, storage containers, mechanical parts, and most other plastic products available today. Injection moulding is the most common modern method of manufacturing plastic parts; it is ideal for producing high volumes of the same object.JHMOCKUP also serve in Household moulds, Plastic Furniture moulds, Thin-wall moulds, Automotive moulds and Pipe Fitting's moulds, etc.
Injection molding is an established process for many exterior automotive components, including fenders, grilles, bumpers, door panels, floor rails, light housings, and more.

In this new era of great changes, many things around us are constantly improving and perfecting. Only technological products that are constantly innovating and changing are more popular. That is to say, our product technology rapid prototyping has a very high speed and efficiency, product production effect is very good. Ming, do not stick together, so how does this rapid prototyping technology compare to traditional technology? Today we’ll take a look.
The rapid prototyping technology adopted by the rapid prototyping device can adapt to the difficulty of manufacturing and processing of various materials in our life, and can obtain excellent materials and structural properties of parts.
As mentioned above, the rapid prototyping technology of materials involves materials, forming methods and structural forms of parts. The essence of rapid prototyping mainly includes the chemical composition of the forming material, the physical properties of the forming material (such as powder, wire or foil) (melting point, thermal expansion coefficient, thermal conductivity, viscosity and fluidity). Only by recognizing the characteristics of these materials can we choose the right material compared with the traditional rapid prototyping technology. What are the characteristics of rapid prototyping technology?
3d printing material rapid prototyping technology mainly includes material density and porosity. In the production process, can meet the performance requirements of molding material microstructure, molding material precision, parts precision and surface roughness, molding material shrinkage (internal stress, deformation and cracking) can meet the specific requirements of various rapid prototyping methods. The precision of the product will directly affect the structure of the product, the roughness of the surface of the product will affect whether there are some defects on the surface of the product, and the shrinkage of the material will affect the precision requirements of the product in the production process.

Advantages of 3D printing prototypes
1. With good complex manufacturing capability, it can complete manufacturing difficult to be completed by traditional methods. The product is complex, and only through multiple rounds of design – prototype machine production – test – modification design – prototype machine reproduction – re-test process, through the prototype machine repeated test can timely find problems and correction. However, the output of the prototype is very small, and it takes a long time and high cost to adopt the traditional manufacturing method, resulting in a long development cycle and high cost.
2. Low cost and fast speed of small batch manufacturing can significantly reduce the development risk and shorten the development time. 3D printing ingot casting with planks do not need to traditional manufacturing mode, system, mold and die forging process, can rapid prototype production, low cost, and digital, the entire production process can be modified at any time, at any time, in a short time, a large number of verification test, thus significantly reduce the risk of developing, shorten the development time, reduce the development cost.
3. High material utilization, can effectively reduce the production cost. The traditional manufacturing is “material reduction manufacturing”, through the raw material billet cutting, extrusion and other operations, remove the excess raw materials, processing the required parts shape, the processing process of the removal of raw materials difficult to recycle, the waste of raw materials. 3D printing only adds raw materials where it is needed, and the material utilization rate is very high, which can make full use of expensive raw materials and significantly reduce the cost.
