Our Powerful Plastic Injection Molding Services

Plastic injection molding is a cost-effective method for obtaining both small and large quantities of plastic parts. NOBLE is a world-class plastic injection molding company that can provide complete manufacturing solutions for your project. We are committed to customer satisfaction, and our custom plastic injection molding services involve on-demand prototyping and production. You can expect the highest quality injection molded parts regardless of size and complexity.

Standard Injection Molding

Plastic pellets are heated to the melting point and injected into the mold under high pressure to fill the cavity. After cooling, the part is ejected. It is widely used in automotive, consumer, and medical parts due to its versatility and high efficiency.

Multi-Shot-Injection-Molding
Multi-Shot Injection Molding

Multiple types of plastics are injected into the same mold at different stages to produce parts with different colors, textures, or material properties in one cycle. Due to its diverse types and strong functionality, it is widely used in car dashboards and button housings.

Insert Injection Molding

It places the preformed component into the mold cavity before injecting the plastic, and the molten plastic flows around the insert and bonds with it after cooling to form a strong integrated part. It is widely used in automotive parts, consumer products, and electrical parts because of its strong bonding and reduced assembly characteristics.

Reaction Injection Molding

It mixes reactive elastic or thermosetting materials and injects them into the mold, where they undergo a chemical reaction and harden. Due to its characteristics of producing flexible and hard parts, it is widely used in automobile bumpers and industrial product shells.

Micro-Injection-Molding
Micro Injection Molding

It injects molten plastic into a very small mold, usually under high pressure, and is usually used for products that require extremely tight tolerances. Due to its high precision and miniaturization, it is widely used to manufacture medical micro parts and micromechanical parts.

Thermoplastic Injection Molding

It uses thermoplastic materials that can be melted and reshaped multiple times, heating them until they are melted, and then injecting them into the mold to solidify. Because it is recyclable and cools quickly, it is widely used in plastic consumer products and medical equipment parts.

Metal-injection-Molding
Two-Color Injection Molding

Two different colors of plastic are injected into the mold in one cycle. The two colors are injected at different stages, or two separate injection units are used to create parts with two colors or materials. It is widely used in consumer goods, car buttons, and mobile phone cases for its aesthetic appeal and enhanced functionality.

Metal-injection-Molding
Gas-assisted Injection Molding

Nitrogen or other inert gases are injected into the molten plastic during molding. This gas creates an internal cavity, which reduces material usage and makes the part lighter without increasing strength. It is widely used in automotive door panels and mobile device housings due to its energy-saving, improved part weight, and surface finish.

Metal-injection-Molding
Stack Injection Molding:

It will use a mold with two or more cavities stacked together to double or triple the production volume of a single molding cycle, improving the efficiency of mass production processes. Due to its high productivity and low cost, it is widely used in mass production of plastic housings and automotive plastic parts.

With our experience and advanced machinery, we excel at designing and manufacturing a series of plastic injection molds adjusted to your tolerance and cost.

Plastic Injection Molding

Our plastic injection molding process uses precise machinery to shoot molten resin into a mold to become a final production-grade thermoplastic part.

Overmolding

Covering plastic, metal, and rubber over each other via chemical bonding, our overmolding reduces assembly time and gives our parts greater strength and flexibility.

Insert Molding

Insert molding is the process of molding thermoplastic material around a preformed component to create a finished part that incorporates multiple materials.

Liguid Silicone Rubber Molding

Liquid silicone rubber (LSR) is a thermoset process to produce a high volume of pliable, durable, intricate, and precise silicone rubber parts. This process first mixes two compounds (generally consisting of the base-forming silicone and the platinum catalyst).

Metal Injection Molding

The Metal Injection Molding (MIM) process combines the design flexibility of Plastic Injection Molding with the strength and integrity of wrought metals to offer cost-effective solutions for highly complex part geometries.

Step 1: Engineers analyze the drawings: Free detailed production DFM reports for further feasibility analysis.

Step 2: Production Arrangement: Determine all requirements and arrange the production.

Step 3: is mold production: put the mold into production, and provide the Tooling Schedule form of the whole cycle for customers to check the process at any time.

Step 4: Free sample test: put the mold into production, and provide the Tooling Schedule form of the whole cycle for customers to check the process at any time.

Step 5: Mass production: After the customer confirms that the sample is qualified, the follow-up production will be officially carried out.

Step 6: Save the modeThe product will be shipped after the production is completed and the quality inspection is pas—cleaner and store molds for the next round of part production.

What are the typical tolerances for injection molded parts?

Tolerances are very important and if not properly specified and controlled, assemblies will fail. NOBLE uses the ISO 2068-c standard for injection molding tolerances unless tighter tolerances are required.

How long does it take to make molded parts?
