Our Process
The first step is to verify that the injection mold design is suitable for manufacturing. Once verified, we can begin the injection mold manufacturing process. Once the mold is finalized, we begin preparations to begin plastic part manufacturing. Before full production begins, we will complete a trial run (T1) and inspect the parts for defects. We will share our observations with you and send sample parts for first article inspection (FAI). Based on the part requirements, we will establish quality standards and conduct process inspections throughout the production cycle. We use state-of-the-art equipment to check the parts for integrity, color correctness, and other common defects that may occur, such as flash, blushing, sink marks, and warping.
Once the sample is approved, we can begin production. Because Xnparts works closely with you to understand your ordering trends, we schedule accordingly to meet your immediate needs. Our goal is to have parts ready to ship from our plastic injection molding facility in Shenzhen, China, when you need them most. We also monitor the quantities on our shelves so that we can help you estimate future needs.

In-House Mold Manufacturing
All Xnparts customer molds are manufactured in-house at our manufacturing facility in Shenzhen, China. Our mold manufacturing area is staffed by experienced designers and machinists using state-of-the-art software and CNC machinery. Once the customer part design is finalized and approved for manufacturing, our team will design and build a solid, trouble-free plastic injection mold to your production requirements.
If your company needs to purchase new tooling for an injection molding project, you should want a single supplier that is responsible for the quality of both the injection mold and the production part. Xnparts’ ability to manufacture your own tooling can help you avoid facing serious quality issues, delivery time delays, and unforeseen costs in your budget.
Types of Injection Molding Processes
Thermoset (Reactive) Injection Molding
Molding with thermoset materials requires heat or chemical methods to cure the material. It uses a similar process to thermoplastic injection molding, but may use a hot mold instead of a cold one. It may also require a cure time instead of a cool time with the mold closed.
Overmolding And Insert Molding
Overmolding is a plastic injection molding process where one material is molded over another. This includes molding over part inserts, such as metal threads.
Gas-Assisted Injection Molding
After the plastic is injected into the mold cavity so that it only fills a portion of the cavity, an inert gas is introduced at high pressure to create an air pocket in the center of the part. This can reduce part weight while achieving a high-quality surface finish.
Co-injection and Bi-injection Molding
This process involves injecting two different materials using the same or different injection locations. One use case for this process is a product with a harder material as the base and a softer, more flexible material as the exterior to withstand a wider range of performance applications.
Microcellular Injection Molding
Uses physical blowing agents, chemical blowing agents (CBA), or a mold core retraction process to trigger the foaming of the polymer inside the mold. This is a way to reduce the weight of a part while maintaining its structural integrity.
Powder Injection Molding (PIM)
This molding technique uses a powder (usually ceramic (CIM) or metal (MIM)) and a binder (usually a polymer) to produce small parts. The processing of this material is similar to traditional injection molding.
Prototyping and Full In-House Services
Your product journey begins with Xnparts’ prototyping team. Our team of technical designers and engineers based in China can transform your company’s existing concepts into finished products. Our injection molding design team will transform simple sketches into fully realized CADCAM designs. Once approved, the final design is ready for the plastic injection molding process. Because we have the ability to design, provide prototype parts, build injection molds, and produce them ourselves, we are able to handle your parts and control the entire process from start to finish. As a result, you can enjoy the industry’s lowest costs and fastest lead times for the delivery of your plastic injection molding products. Our design team will meet with you to discuss your products and goals, as well as our processes and logistics.
Plastic Prototyping Alternatives
3D printing manufacturing methods can produce prototype products faster than plastic injection molding. High precision and automated processes can produce parts and molds for prototype testing, thereby reducing costs. Customization options allow flexibility in part design and material properties such as color, transparency, strength and flexibility. If you are not sure whether the part or mold design is suitable for large-scale production, you can choose 3D printing for verification.

What is Injection Molding?
Injection molding is a manufacturing process used to produce precision, cost-effective plastic parts in large quantities. The process involves injecting molten material into a custom-designed mold, which primarily determines the shape of the part. After the material cools and solidifies, the mold opens and the part pops out. This process is ideal for making complex parts with tight tolerances and is popular because it can be produced economically in large quantities.
Advantages of Injection Molding
- The precision of injection molded parts is very high. Especially in the field of engineering, having precision-made parts can reduce wear and tear on moving parts. With precision down to 0.005 inches, you can expect everything to screw tight, fit snugly, and require less maintenance over time.
- A single, solid part is always better than having additional connection points. Injection molding is very versatile, and many times, parts can be molded as a single piece without any screws or potential weak links.
- The flexibility of plastic selection makes injection molding a good choice for almost any plastic. Plastics vary greatly in tensile strength, durability, and flexibility.
- Specialized high-strength fillers can be added during the injection molding process to enhance the strength of the finished product.
- With injection molding, a smooth surface on a part can be easily achieved. Without the need for additional surface treatment, this efficiency saves time and money.
