Plastic Injection Molding Service

At Ucreated,we specialize in rapid molds of both aluminum and steel and low-volume plastic molding. With technical experience in injection molding, rapid tooling, CNC machining, EDM processing, and specialty finishing, we ensure your molded parts meet and exceed your highest expectations.

We invests in an independent injection molding factory which can use various materials and techniques to create bridge tooling for prototype testing and pre-production evaluation. We deliver injection molded parts on your schedule to support your entire testing, and help troubleshoot possible process issues in full production.

How Plastic Injection Molding Works

Plastic injection molding is by far the most common way to produce large volumes of finished plastic parts for every kind of commercial and industrial use. Molten resin is injected under high pressure into the cavity of a metal die and then rapidly cooled, forming a solid shape. A single cycle to make a finished part may take anywhere from a few seconds to minutes depending on part complexity and size.

The Plastic Injection Molding Process

The molding process consists of the following basic steps:

Step 1. The plastic resin comes in raw pellets. These are dried to the right moisture content, and then if necessary they can be blended with pigments or master batch colorants.

Step 2. The dried pellets are poured into the hopper of the molding machine. A reciprocating screw inside the barrel of the machine will transport these pellets towards the mold.

Step 3. Within the barrel, the pellets are mixed and heated until fully molten, forming the liquid resin.

Step 4. The heated mold closes automatically and resin, under great pressure, is injected through a gate and into the mold cavity.

Step 5. The mold is cooled to solidify the part inside.

Step 6. The mold opens and the part is ejected to begin a new cycle.

Plastic Injection Molding Question

What plastic is used in injection molding?

Virtually any type of plastic can be used in the injection molding process. There are thousands of thermoforming and thermosetting plastics to choose from for your projects

Can you make exported mold?

Yes,we can. Ucreated have capability to make the mold and export it, which is total different from the material and manufacturing process.

What are the advantages of plastic injection molding?

Once a tool is made, plastic injection molding is the fastest and most cost-effective way to manufacture thousands of finished parts.

How long does it take to make an injection mold tool?

Depending on the complexity of the design and possible heat treatment, a rapid tooling normally takes around 2 weeks.


What makes Ucreated’s plastic injection molding service unique?

Our plastic injection molding service is strengthened by our extensive expertise and a wide range of production capabilities. We have a more than 10 years tooling maker team who can provide you with professional design for manufacturing reports.

Can Ucreated provide design services, industrial design support, or product development support as an extension of its plastic injection molding services?

Yes — to assist with product design, we have partners who can offer the design service. Also, we could do the modified design if needed for manufacturing.

What are Ucreated’s quality standards for its plastic injection molding services?

Our quality-control system includes several steps to ensure safe, high-performing products for our clients. As with all of our services, we conduct comprehensive material verification and testing before molding begins. During production, we carefully control all processing conditions — including temperature and humidity — to maintain repeatable results. Many competing plastic mold injection services neglect to do this, which can lead to flaws in the finished parts. We also implement 3D scanning of complex shapes to ensure precision, accuracy and easy design manipulation when necessary.

What plastic mold tools and part materials do you offer?

Our team makes plastic injection molding tools and dies from S136H, 2316H, H13 hardened, 8407 and NAK80 semi-hardened steels. We offer standard SPI finish and EDM texture.
