SINO AUTO MOULD – A Leading Automotive Parts Mold Manufacture in China

Auto molding industrial include many molding technology, such as gas assistant molding for door handle parts, Bi-material molding technology and so on.

With our qualified team and professional tooling engineers, we offers our international market with auto molding service include injection mold for plastic automotive exterior parts and interior part. 

The present auto molding condition we can say as follows:

The design software is CAD/CAM, which widely used in Chinese molding factories.  To make automotive moulds, there are some points very important. The design control before analysis is the first key point for getting this project start. SINO can use mold flow software for study the gate locating, material heating transfer, air venting and pressure condition during auto molding process. So that we can fast avoid defects for the plastic molding process.

High speed tooling and high précised tooling equipment are more and more mature. As years ago, Chinese auto molds manufacturers are very hard to achieve the high precision requirement due to the precision standard is not reaching. Nowadays, with the bringing in of international brand CNC milling equipment, the tooling speed and tooling precise are greatly improved.

Hot runner technology is widely applied for auto moldings. We can include the hot runner selection such as sequential hot runner valve gates for some auto parts such as bumpers, control penal and so on. Hot runner system reduces very much the material waste and makes the plastic molding parts better appearance and efficient injection molding process.

Very advanced steel material heat treatment technology. The aluminum alloy are more and more used to make the auto molding, due to the advantage of material less density, good heat transforming, good welding feature and cutting advantage. Therefore, the tooling lead time for auto molding is also short.

SINO AUTO MOULD passed ISO9001 and TS16949 certificate. Through the improvement of the quality control system, SINO AUTO focuses on mold performance, high efficiency, high lifetime and pursuit of energy saving and user-friendly features.

As the leading automotive parts mold manufacture in China, SINO AUTO MOULD is now more and more developed in auto molding technology. SINO MOULD place great importance in R&D of innovative automotive moulds structure research, improvement and analysis.

Once the order start, SINO team start analysis by software with technical chief engineers and come to an perfect conclusion for parting, molding defect avoiding, molding structure draft and artwork layout. Then, we will start the design for making the project for 3D model and 2D modeling. This process, Also, the cooling system of auto molding is very strict. The cooling system designed for this mold, must be able to control the molding surface area within 5 degrees. Making the reasonable structure for ejection and angle lifters is also required in our design and so on.

Following the design output, steel purchase and mold components purchase and QC inspection is coming in and order. The material will be included with steel sample and texture plate for offering the OEM companies for stock and checking.

By following 2D tooling tolerance drawing, inspection department will check step by step the tooling semi-finished parts and components. Through testing and 3D CMM, SINO is able to achieve the workshop of mold components and mold assembly quality inspection and quality control process. The principle of SINO QC in the auto molding mold production process is tracking and to detect and solve problems to prevent errors and avoid a defect elements flow into the next tooling step.

When all components and mold blocks come to assembling, the auto molding trial with right material is also very critical. Therefore, SINO set up our own tooling parts QC report, assembling process, checking the result of the assembling quality and progress will be reported to the QC records system for 2nd QC control.

An Introduction to Plastic Injection molding machine & its materials

Plastic injection molding is a method of plastic products, using the pressure of the molten plastic injected into the mold of plastic products, and cooling molding to obtain the desired variety of plastic parts. Specialized machinery for injection molding injection molding machine

Plastic Injection mold

The mold is obtained after the resin material is injected into a metal mold apparatus of the products having a certain shape. Although not indicated in the drawings, in fact, in order to control the temperature of the mold, on the mold so that refrigerant (warm water or oil) through the cooling holes, such as a heater means. Melt the material has become the mainstream Road, injected into the cavity through the shunt, the gate. After cooling stage to open the top of the mold, molding machine the top of the device will be the peak of the staff, the product launch.

The resulting shape is often the final product in the installation or as a final product before use is no longer the need for other processing. Lot of detail, such as the convex portion, the ribs, threads, can be molded in the operation of the injection molding step.

Plastic Injection molding machine

Plastic Injection molding is the heat to melt the material by a high pressure enters the mold cavity, after cooled and solidified to obtain a molded article. The plastic injection molding process can be divided into the following six stages clamping, injection, packing, cooling, mold products remove.

The plastic injection molding machine has two basic components: the injection means and a mold clamping device for melting and feeding the plastic into the mold. The role of the mold clamping device in that: the mold under the live injection pressure case closed. Remove the article to the injection apparatus in the plastic injection mold prior to its melting and then control the pressure and velocity of the melt is injected into the mold. The two designs: the screw preplasticator or dual-level device, as well as reciprocating screw injection device. The screw preplasticator pre-plasticizing screw (first-class) and then melt the plastic injection material rod (second-class).

Plastic material

What are the types of plastic injection molding? Many different types of plastic, generally divided into thermoplastic and thermosetting plastics, thermoplastics after when heat softened or melted knot hard after cooling, again antipyretic still softened or melted. Is a kind of plastic, polystyrene (PS) (applied to transparent products and foam, etc.), polyvinyl chloride (PVC) (used in building pipe, etc.), polyethylene (PE) (used in day-to-day supplies more), polypropylene (PP) (applies to repeatedly force the product), acrylonitrile butadiene styrene (ABS) (uses extensively), polycarbonate (PC) (commonly known as the bullet-proof glass, widely used require high impact strength of the transparent product); poly phthalazine amine (PA) (used in self-lubricating property parts); poly of formaldehyde (POW (like PA); polytetrafluoroethylene (PTFE) ( applied the anti-corrosion products). thermoplastics with high production efficiency, good mechanical properties and dielectric properties of the advantages of lower heat resistance and stiffness, and some have reached new thermoplastic thermosetting plastic heat resistance.

Only by this way, China plastic moulding suppliers can realize high efficiency, low material and power consumption to reduce the cost of the unit molded component, to save cost for our customers.

Plastic injection molds are metal forms created to produce a specific plastic item. These molds are the primary way that all plastic parts are manufactured. Heating and melting granules or pellets of plastic begin the process. The liquefied plastic is then forced, injected, into the closed split-die mold under high pressure and allowed to cool. The plastic injection mold is then opened to release the product.

Once a product has been designed, plastic injection molds are made, usually of either steel or aluminum, and precision machined to form the smallest feature of the plastic product. Often several plastic injection molds are used for a product that has numerous parts. Plastic injection molds have both core and cavity inserts, which will correspond to the shapes desired.

The material used for injecting into the plastic injection molds is derived from two different basic plastics: thermoplastic and thermosetting plastic. Most familiar plastic items are made from thermoplastics because these meltable plastics can be shaped and reshaped easily. Thermoplastics are used to make such common items as milk containers, soft drink bottles, pantyhose, Styrofoam cups, plastic toys, etc. This type of plastic is easily recyclable as used products can be melted, injected into molds, and reformed into new items.

Thermosetting, or thermoset, plastics are rigid and set in a one-time pattern when they come out of the plastic injection mold. They cannot by recycled or melted for further use. Examples of thermoset plastics are automobile tires, appliance cases, electrical and electronic circuit boards, and electrical switches.
