Injection mold & Low volume injection molding company
From part design to final delivery

Mould for plastic injection, known as Injection plastic molds, is commonly used for producing high volume plastic parts. With a large plastic injection molding machine, injection plastic molds can output large plastic parts. With a smaller plastic injection molding machine, injection plastic molds can make precise and small plastic products for medical applications. In addition, there are many types of plastic additives that can be used in the injection plastic molding process, increasing its flexibility for product designers and engineers.

Stebro Mold Co Ltd as a professional injection plastic mold maker, is still trying to provide excellent injection molding service for its customers. We have R&D basement and will connect with our customers during the whole cooperation. Perfect injection molding parts and professional service than other plastic mold maker are our pursuing.

Many companies have found that injection plastic molds manufacturing overseas is cost-effective. You may probably heard bad stories about the Chinese injection plastic molds being of low quality. But the outsourcing market of plastic injection molds China has grown steadily, there are many plastic manufacturing companies all over the world that continues to buy China plastic injection molds or China plastic injection molding service; some of them placing big volume orders and some even opening their own office in China to source injection plastic molds from injection mould company in China.

1. China plastic mold makers can provide lower price with high quality. In China, there has lots of plastic mold makers and injection molding manufacturers as you known, thus there has a fierce competition in injection molding industry. This situation takes a result that Chinese plastic mold makers & plastic injection molding companies could provide higher quality with lower price. Though Chinese molding price is lower than Europe, the quality it provides is no less excellent than Europe.

Finding an injection plastic mold maker as your molding partner is a good choice. Creating molding business which China plastic mold maker will take lots of advantages for you than cooperate with other plastic mold maker.

Usually, a plastic injection mold costs between $1,000 to $90,000.

Steel selection in the plastic mold can be as critical to the success of a plastics application as the selection of resin is to the end use performance requirements of the Plastic Injection Molded Product. The correct steel hardness must be determined to maintain the proper balance between wear and toughness so tooling components don’t wear out prematurely.

Polishing and Texturing are the two main considerations for the injection mold steel surface.

• Polishing: Polishing is a manual process that removes machining marks on the plastic mold surface and provides a uniform finish.
• Texturing: There are several ways to texture a plastic mold surface such as sand blasting, EDM or Etching.

The choice of surface finish needs to be established very early in the design phase. The reason for this is because the finish type influences the tooling that needs to be used during the manufacturing process. The rougher the finish, the higher the draft angle needed to be able to easily eject the part from the custom injection molds. No matter what kind of surface finish you desire, Stebro Mold will be sure to exceed your expectations.

Once we understand your needs and optimized the part design, we will start the mold design. The main goal of mold design and tooling is to create a product with highest possible manufacturability. That means a high-quality process that is simple and efficient, long-lasting, easy to operate and maintain, and that meets all customer specifications—all at the lowest possible cost. From flow analysis to runner and gate sizing to cooling analysis to venting recommendations to temperature and pressure sensor recommendations, we’ll look at every aspect of injection mold design to ensure your custom injection molds are as close to perfect as possible.

Stebro Mold Co Ltd manufactures a wide range of custom plastic molds from prototypes to complex final production molds. Our custom injection molds types including:

Injection mold lifetime stands for the number of moulding cycles a mold can make before it needs to be replaced. Any injection mold will be subject to wear.
Plastic injection mold wear will occur particularly to ejectors, gates, slides and other moving parts. Surface finishes such as high gloss polish or sparked finish will also become less defined over time. The mold wear mainly depends on below items: Mold complexity, Injection Mold Steel, Injection Molding Material, Mold setter skill and regular mold maintenance. If the Injection mold have lots of actions such as sliders, lifters, unscrewing mechanisms with many small core pins, molded with high glass-filled material, the moldlife will be shorter than a simple injection mold molded with PP material.

You can take an estimate for mold’s lifetime, which will help you determine whether or not a plastic injection mold live up to its estimated performance. If your injection mold only completed 180,000 before breaking down, while the expectancy of the injection mold was 250,000 cycle, the reason for this performance might be that the operation of molding process is too faster and wear and tear were happened. But the problem might also lies in the mould design. As a professional plastic molding company，we will provide perfect solutions to solve your molding defects.

As long as we’re running your parts in our manufacturing facility, your mold is covered with a lifetime warranty, that means we will maintain, adjust, repair or replace the mold as needed, at no cost to you within the mold lifetime. And in this feild Stebro plastic mold maker promise we have advantages than other plastic mold makers.

Once an injection mould has run a set number of cycles; inspections, maintenance and cleaning should be performed. Regular maintenance and cleaning can improve the shot quality, which ensures consistent plastic parts quality. Injection mold repairs can be costly, so it is important that your injection plastic molds maker provide regular maintenance, cleaning, and if necessary, repair, to protect your mould investment and maintain consistent production. At Stebro Mold Co Ltd, we stand behind our injection mold tooling. As long as the plastic injection mold remains with us we will guarantee that mold for life.
