Our Injection Molding Capabilities

From plastic prototyping to production molding, our custom injection molding services are ideal for manufacturing high-quality molded parts at competitive prices with fast lead times. Robust manufacturing facilities and sophisticated machines ensure that the same mold tools are used to manufacture consistent parts. Even better, we offer free expert consultation for each injection molding order, including mold design recommendations, end-use material and surface treatment options, and shipping methods.

Plastic Injection Molds

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.

DFM Report

To ensure we can produce functional molds, we offer feasibility reviews of your design to ensure we can fulfill requirements before starting production.

Mold Flow Analysis

Predictive modeling software helps us look at the way molten material moves and acts within the mold, which helps us deliver improvements.

Mold Tooling Production

Start the production of mold tooling according to your specific application needs by using the materials and finishs of your choice.

T1 Sample Verification

T1 sampling will be delivered for you to review prior to manufacturing plastic parts to ensure precision and quality.

Low Volume Production

After completing the trial production phase, we proceed to low volume production, utilizing advanced machining techniques to manufacture parts quickly and efficiently.

Strict Inspection

A strict inspection process, including the inspection of function, dimension, and appearance, ensures that the parts meet the required specifications and are of high quality.

Delivery

After a thorough inspection, we will deliver your products to you as quickly as possible while ensuring their safety.

Surface Finishes of Injection Molding

Injection molding includes injection mold tooling, plastic injection molding, and more. The surface treatment of the mold is usually completed during the production process. After the injection molding is completed, we will carry out certain surface treatments on the finished product as per your requirement.

Glossy

A grade finishes are made using a diamond buffing process and yield shiny and glossy surfaces on injection molded parts.

Semi-glossy

B grade finishes use grit sandpaper to produce parts with a slightly rougher finish than grade A parts. Custom molded plastic parts that undergo B grade finishing have a matte surface texture.

Matte

C grade finishes use grit sanding stones to produce a rough, uneven surface. Injection plastic parts that undergo C grade finishing have a matte surface texture.

Textured

D grade finishes use grit and dry glass beads or oxide to produce a very rough textured finish. Depending on the type of material used, products can have a satin or dull finish.

Frequently Asked Questions

No minimum order quantity, but the oder pricing will be more competitive if qty is higher.
Our mold-making process includes 6 steps:
Step 1: Production arrangement: Determine all of the requirements and arrange the production.
Step 2: DFM report analysis: Provide free but detailed production DFM report for further feasibility analysis.
Step 3: Production of the mold: Put the mold into production and provide the Tooling Schedule form for the whole cycle for clients to check the process at any time.
Step 4: Free sample to test: Put the mold into production and provide the Tooling Schedule form for the whole cycle for clients to check the process at any time.
Step 5: Mass production: The client confirms the samples are qualified, then officially proceeds with the subsequent production.
Step 6: Mold saving: Production is completed and delivered after quality inspection. Mold will be cleaned and properly stored for the next round of parts production.
Tolerance is very important, and if not correctly specified and controlled, assembling will fail. RapidDirect uses ISO 2068-c standard for injection molding tolerances unless tighter tolerance required.
After you place order, it takes about 35 days for mold designing and making, and more 3-5 days for molded parts production.
Generally, we generate the quote after our platform must have considered several factors, including the size of the component, mold complexity, number of injection cavities, materials, post-processing needs, etc.
