Plastic injection is the most common process used for manufacturing plastic parts. The production tooling and injection molding are ensured by molding factories. Workshops or plastic injection molding factories possess different kind of machines, such as injection press for instance. Injection molding factories usually specialized in different activities and offer different materials and finishing. Those mold makers use different kind of machines and accessories to accomplish production. These machines process thermoplastic materials, the most common been ABS, PC, PP and Nylon. A custom plastic injection molding enterprise provides High-Volume plastic parts.
Prototech Asia: plastic injection mold factory in China
Our plastic injection molding factory has been established in China in 2006. In addition to the plant, we own two engineering offices based in China and in France. The team is made of 50 people, including manual workers, designers, and plastic engineers. Our designers are able to analyze your 3D files and provide our opinion regarding your project, whether to modify it or not.
How to find your plastic injection mold factory?
There are common sense criteria to identify and select a mold maker to ensure the production of your project. Here, we may for instance list notions such as cost-effectiveness, quality, and level of customer support. What’s more, plastic injection molding factories are usually focused on specific expertise, for instance, pharmaceutical, automotive or household related equipment.
Therefore, it is necessary to find a plastic injection molding factory which tools and materials enable the realization of your project. Besides this information, a visit in person is highly recommended to confirm the skills of the mold maker.
Nevertheless, you may also evaluate a plastic injection factory through several criteria such as:
- Level of reactiveness in answering inquiries and following projects.
- Level of technical knowledge and abilities during the design and production phases.
- Equipment used for production (machines and tools).
- Software equipment quality (Solidworks, Catia V5, Moldflow…).
- Abilities of the team, including engineering and languages skills.
- Past experience rich of numerous projects, various sectors and technical requirements.
- The efficiency of the test center.
- Quality control (dimensional reports).
- Level of precision and rendering of produced parts.
Additionally, other ways to assess the strengths of a plastic injection mold factory are the existing clientele, list of treatments and applications (hinges, transparent parts…) available, number of accessories necessary for injection and mold quality.
To finish, concerning logistic issues some mold makers also provide exportation services, meaning they do ship the mold to the client even when two countries are involved. On another hand, it may happen that some injection factories retain in-house the molds, providing only the injected parts.
More technical information about Plastic injection molding
1) Injection molded plastics steps and services:
a) Design and engineering:
- Production of plastic injection molded parts may be improved by geometries such as notch engineering.
- Two-shot molding or insert molding are engineering methods used to decrease price and lead times. They are especially useful regarding high volume production when requiring multiple resins for instance.
b) Custom tool-making resources:
- Equipment: a mold is produced with CNC machines, such as CNC 4 axis milling and lathe, EDM and plastic injection molding machines (Injection press).
- Team: experienced molders include mold designers, plastics engineers, and manual workers.
c) Injection Molding:
2) A tool maker offers several thermoplastic injection molding solutions:
- Manufacturing of steel and aluminum molds
- Production of injection-mold products used in OEM and other companies
- Secondary operations such as shortened cycle times, assembly and consulting.
3) Main challenges for plastic injection mold manufacturer are:
- Parts requiring exotic materials and/or Complex geometries
- applications related to Metal or Rubber replacement
- Tolerances difficult to hold
In short, plastic injection-molding is a technology to manufacture high-volume plastic parts. A plastic injection molding factory produces a mold from 3D files of plastic parts. In aluminum or steel, the mold is inserted in an injection press to start the industrialization process. To finish, an injection molding service company often provides rapid prototyping services to validate the drawings before to start the mold production.

Hi, I want to get various injection moulding moulds. Can we connect on whatsapp- +91-8076197500
Hello, My name is Michael Tang and I work at Shyft Global in the United states, a supply chain management company. We’re looking to partner with a medical plastics manufacturer and found your company. We have a client who wants to make a unique single-use plastic medical tray. This tray catches fluids as doctors perform surgery, like eye surgery. We must have FDA certified and ISO 10993 certified PET plastic. We are looking to partner with a factory that can help us make two trays, one is thermoformed and the other is injection molding. Maybe you can help us with the Injection molded one.
We’re looking to get a quote for our product for quantities: 10k, 20k, 30k, 50k, and 100k.
Looking forward to your reply,
Michael Tang
Hello Mister Tang,
Many thanks for your comment.
We can help you for your injection molding project. As the quantity is too high for Prototyping, we will put you in contact with our mother company Unimold Asia.
We are specialized in injection and we have all the knowledge and experience to fit your needs.
We will be in touch with you shortly.

Hi, does vacuum mold casting and injection molding produce by using the same mold? If yes could you please explain the difference
Dear William,
Many thanks for your comment,
No, there are two different molds used. A silicon mold is used for vacuum casting while a steal of aluminium mold is used for injection molding
Greetings!
Is a volume of 100 pcs to low to start production by injection molding?
Dear Vanessa,
Many thanks for your comment,
What technology should be used for your parts does regard to the mechanical properties of the part. We already did projects with 100 parts done by injection molding but most of the time we use vacuum casting. Please send us your 3D files of the part and we will come back to you soon with a solution and an offer.
