Before we spent lots of money to make molds, some new project investor will make rapid prototyping to check the mechanical function or verify the designing,rapid prototype can be made of plastic,steel or aluminium.at the monment we have many methods to make prototypes, such as CNC machining, SLA technology and Vaccum custing technology.

Rapid Prototyping (RP) is a quick and economical way to make the sample according to your drawing or your idea, you can do assembly to verify the mechanical function, we can make painting,silk print and runner coationg,as the technology develop,the finish of prototypes reach the same level of mass production product.then you can see the real aprearance of your designning,sometimes customers use rapid prototype for business exhibition as real product.Good quality prototype is one of the reason,another important is the economic cost and short lead time,rapid prototype normally take one week,but molds will take one month at least,cost is also different,prototype will cost less than 300USD,but molds cost more than 2000 USD even if you find the cheapest mold manufacturer in China.

Also the rapid protyping have another important function:find the mistake or imperfection in the designing at the beginning of R&D and help designer optimise the designing step by step,if you find the problem after you build the mold,it will take thousands of USD to modify the tooling.

CNC Machining prototyping
This is most popular way to make rapid protypes in China.first ,the CNC machines is not expensive as others,it is less risk to invest the equipment.Second,they can make large size prototypes
Max size up 1100mm x 650mm x 470mm,
Advantages: Large size, high strength, good toughness, short delivery time.

SLA technology
tereolithography (SLA or SL; also known as optical fabrication, photo-solidification, solid free-form fabrication, solid imaging and Resin printing) is an additive manufacturing or 3D printing technology used for producing models or prototype
Application: toy, electric case parts with complex surface
Advantages: complex structure capable, high strength

Vacuum-custing technology
Produce a silicone mold with a prototype part under vacuum, use the silicone mold to clone parts.
Advantages: Low cost, fast, it is very cheap to duplicate the prototypes,it have big advantage if you want 10-50 pcs parts.

As we kown, the auto business develop very quickly in past ten year,more and more newest go to the market, lots of automovtive components are made from plastic,that means it need large amount of molds made.

As a new material for auto parts, plastic parts can reduce the weight of cars and is energy saving, thus are widely used in auto industry. Plastic material gives auto manufacturer more flexibility in car design, i.e.: inner decoration spare parts, panels, door trims, ABS breaking system, bumpers, triangle, spoiler, etc. Our company has certified by ISO9001, along with professional design team, high performance equipment, we have been cooperative partner of many car manufacturers both china and overseas. our company are capable of providing integral design, structural design, auto mold development, product injection, including panel, door trims, air condition, and bumper analysis for Automotive Parts Molding.

Product design and mold flow analysis
In the process of product design, mold flow analysis software is used to work out best point of the flow. At the same time, to minimize cooling effect, cycle time, warping problems of the product, thus avoiding deformation, welding mark, shrinkage problem. Every important assembling part will be check by jigs and gauges to make sure that all products fit well in its set.

Auto mold processing technology
Measuring is of high importance in automotive plastic mould, which affects the assembling and fitting effects of all auto parts. The five-axis nc machine can speed up the feed process, shorten manufacturing cycle, optimize tooling system and simplifying processing cycle time and guarantees the precision of the auto mold.

Auto parts injection technology
In the process of injection, material property, clamping tonnage, injection pressure and cooling system should be taken into serious consideration. Auxiliary equipment as water chiller, mold temperature controller machine should be used when necessary, thus to shorten the cooling time and to improve productivity. Spare parts should be put carefully into specially appliance in order to preserve it well.

PVC pipe fittings Mould ( for high pressure and low pressure，for water supplying and water discharging) ，PVC is sometimes known as ‘Vinyl’ in Europe and predominantly so in North America. In Europe, ‘Vinyl’ usually refers to certain specific flexible applications, such as flooring, decorative sheets and artificial leather，This chlorine gives to PVC excellent fire resistance。

Nowadays people start to use PVC for pipe fitting,because they are much cheaper and durable compared to metal ones,our field cover as follow:
1. CPVC pipe fitting for high pressure.
2. UPVC pipe fitting for water drainage
3. PVC belling pipe fitting mould( with collapsible cores for pressure water supply).
4. Electricity cable pipe fitting, built in-wall various PVC pipe fittings.

The technical solutions for PVC pipe fitting moulding and PVC pipe fitting mould manufacturing. PVC is a kind of special material which need special injection molding process.

Injection molding is the most commonly used manufacturing process for the fabrication of plastic pieces. A wide variety of products are manufactured using injection molding, which varies 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.

Plastic parts are used in a variety of products including home 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.

the plastic parts have many advantages compare to metal parts, glass, wood.such as lightweight, cheaper price, and the cycle of production will be shorter the different hardness and chemical stability. and better insulation performance.

As we know, if you want to produce a plastic product,you should make a injection mold tooling first.the mold is the key equipmemt for the shape.so let’s lear what the injection mold tooling is.

The injection molding process uses molds, typically made of steel or aluminum, as the custom tooling. The mold has many components, but can be split into two halves. Each half is attached inside the injection molding machine and the rear half is allowed to slide so that the mold can be opened and closed along the mold’s parting line. The two main components of the mold are the mold core and the mold cavity. When the mold is closed, the space between the mold core and the mold cavity forms the part cavity, that will be filled with molten plastic to create the desired part. Multiple-cavity molds are sometimes used, in which the two mold halves form several identical part cavities.

The mold core and mold cavity are each mounted to the mold base, which is then fixed to the platens inside the injection molding machine. The front half of the mold base includes a support plate, to which the mold cavity is attached, the sprue bushing, into which the material will flow from the nozzle, and a locating ring, in order to align the mold base with the nozzle. The rear half of the mold base includes the ejection system, to which the mold core is attached, and a support plate. When the clamping unit separates the mold halves, the ejector bar actuates the ejection system. The ejector bar pushes the ejector plate forward inside the ejector box, which in turn pushes the ejector pins into the molded part. The ejector pins push the solidified part out of the open mold cavity.
The mold life is different depends on the steel of inserts,if the inserts are made by pre-hard steel.the usual mold life is 300,000 shots.if the mold core and cavity inserts made by harden up steel,such as 1.2344,the mold life will reach 1,000,000 shots. The mold tooling is not cheaper because that the material(steel) is expensive,the process is very complicated and need rich experience staff.the price ranged from 1000-300,000USD
