How Does China Plastic Injection Mold Work?

The first step in the plastic injection molding process is to come up with the idea of making something useful, and then designing the product with cad software. You will need to design your part by using CAD software, such as the medical plastic injection. Once you have designed your part and mold, you can begin to create the tool path for cutting out the metal shape of your part. Now that you have your design, it's time to put it into a mold. You'll need to select the type of plastic material, which is most common done with a resin identification code (ric). You can find this information in your CAD file or on the product's packaging. In this step, we clamp the mold onto the injection molding machine and let it heat up until it's hot enough to melt the pellets of plastic into a liquid when they enter underneath the ram. This process makes sure that nothing is trapped inside, which could cause defects in your product.

A molten pool of plastic forms under the ram as it pushes forward, filling in every nook and cranny of your mold cavity. After injecting the molten plastic into a cavity within a steel or aluminum mold, we remove it from the press so that it can be cooled and hardened.

Once the plastic has been injected into the mold, plastic injection molding manufacturers remove it from the press so that it can be cooled and hardened. The mold is then cleaned up and inspected for any damage. Once we've verified that everything looks good, plastic injection molding factories workers will inspect your part as well.

China Plastic Injection Mold Design

In the process of China prototype injection molding such as the electric plastic molding, plastic injection molding design is a critical part of the process. Molds are made up of two main parts: cores and cavities. The core is where your plastic will be injected, and it's usually made from different plastic injection molding materials based on what kind of plastic you're using—for example, ABS requires an aluminum or steel mold for injection molding because ABS melts at a higher temperature than many other plastics. The cavity is what forms the shape that plastic injection molding factory will use as an injection-molded part. It's typically made from solid steel blocks (or sometimes multiple pieces).

The first step in plastic injection molding design involves creating a CAD model of your product designs so they can be used to create 3D molds with accurate dimensions. This step also helps facilitate communication between designers and molders so there aren't any misunderstandings about how parts should look once they're finished being molded. After this stage has been completed, it's time to move onto creating prototypes using the tools described above! These prototypes help illustrate exactly how products will look before going through production.

FAQs of China Injection Mold Services
QHow many times can an injection mold be used?
A
Aluminum mold is about 6,000 -12000 cycles. But the full-scale steel injection mold production can stand 100,000+ cycles.

Mold life: high hardness of mold steel, made of injection mold wear resistance, long mold life. Aluminum alloy hardness is low, aluminum alloy made of poor wear resistance of injection mold, mold life is short.

Mold weight: the injection mold made of mold steel is heavy, and the injection mold made of aluminum alloy is light.

Mold manufacturing cost: mold steel injection mold made of high cost, aluminum alloy injection mold made of low cost.

Mirror polishing performance of mold: mirror polishing performance of injection mold made of mold steel is good, but mirror polishing performance of injection mold made of aluminum alloy is poor.
How many cycles does an injection mold?
A
First of all, we should see what material products, when choosing materials to do the mold to define, we are need to customize the mold material suitable for this material. There is usually a mold material report. P20 or 45# steel general ordinary mold design at least 300,000 mold times, the life of many molds can reach 1 million mold times, of course, usually need to maintain good.
How long does it take to injection mold plastic?
A
Different mold manufacturers, manufacturing a pair of injection mold under the premise of the same quality is not the same time. Some people think that the longer the cycle, the finer the workmanship, the better the quality. In fact, this is wrong, because they are not professional, so they need longer time to manufacture, and because they are not professional, they need more time to repair. But it is not the shorter the better, because this whole mold manufacturing process takes time.

The normal time for professional mold manufacturers to manufacture a pair of injection mold is 50-65 days, depending on the degree of mold difficulty, the minimum time of conventional mold is generally 30 days, the longest time is generally not more than 75 days. Only professional manufacturers with years of production level to make a pair of high-quality injection mold.

PROTO-MOLD is a very professional injection MOLD manufacturer. We continue to innovate and optimize the mold structure to provide high quality injection mold. For injection mold, now many manufacturers can do. But just because you can do it doesn't mean you can do it well. No matter what things, only the most professional is the most trusted customers. As a professional mold manufacturer, in many years of mold production experience constantly summarized and explored, now has a set of injection mold design concept and manufacturing process. In the design of every detail is through careful analysis of certification, in the work is also put in the hands of injection mold manufacturing for many years.

Proto-mold has always insisted on doing the most professional things, give customers the most convenient service, WE believe that our professional can solve your problems!
