Top 10 Plastic Injection Molding Companies in China for 2026

The right plastic injection molding company in China depends on what your program actually needs. If you are developing a new consumer product from concept to mass production, a one-stop OEM/ODM partner is usually more useful than a pure molder. If you are buying precision medical or automotive components, regulatory and metrology capabilities matter more than price. If you are still validating a design, a rapid prototyping supplier that also offers bridge tooling will get you further, faster. This guide compares ten injection molding manufacturers operating in China across tooling, molding, secondary processing, assembly and project management, and explains which type of buyer each option tends to suit.

What this list compares

The companies below are compared on the factors that most often decide whether a molding project succeeds: in-house mold design and manufacturing, molding capacity and process range, secondary operations such as finishing and welding, assembly and testing capability, quality systems, communication and project management, and the customer profiles each business is set up to serve. Pricing is deliberately not ranked, because tooling and part cost depend on part geometry, material, cavitation, tolerance, volume and logistics, and only a project-specific quotation is meaningful.

How these plastic injection molding companies in China were selected

This is an editorial shortlist based on publicly available business information, not an official industry ranking. Companies were included when they met most of the following conditions:

• Clear, verifiable business focus on mold making, injection molding, or integrated contract manufacturing in China.
• Tooling plus molding, rather than only one of the two, so that design-for-manufacturing feedback and mold ownership stay in one place.
• Documented process range beyond basic molding, such as finishing, welding, printing, assembly or testing.
• A defined customer profile, so buyers can judge fit rather than guess.
• Different use cases across the list, from high-volume electronics to precision technical parts to concept-to-production OEM/ODM programs.

Limitations to keep in mind: no supplier data was supplied for this article, and published information about manufacturers changes frequently. Capacity, equipment counts, certifications, lead times and pricing must be confirmed directly with each supplier for your specific project. Online visibility is not used as a measure of manufacturing strength — several capable molders in China have a limited web presence, and a large marketing footprint does not by itself indicate better tooling or quality control.

The top 10 plastic injection molding companies in China

1. DAYIN Plastic Products Co., Ltd.

Best for: brands, product developers and OEM/ODM buyers who want one partner to take a product from concept, drawings or samples through engineering, tooling, molding, post-processing, assembly and mass production.

What it does: DAYIN is a B2B manufacturing solution provider founded in 1989. Its core business covers product R&D and engineering development, industrial and structural design, DFM and mold flow analysis, precision injection mold design and manufacturing, prototype and sample development, plastic injection molding, secondary processing and decorative processes such as printing, hot stamping and laser engraving, welding, electronic assembly and finished-product assembly, testing and quality inspection, and OEM/ODM manufacturing with mass production and supply-chain support.

Why it stands out in this comparison: the company positions itself as an integrated service chain rather than a single-process supplier. Because engineering evaluation, mold development, sample verification, molding, post-processing, assembly and testing sit inside one organisation, design changes and tolerance issues are handled without moving a project between vendors. DAYIN operates manufacturing facilities in China and Vietnam, which is relevant for buyers evaluating country-of-origin diversification or tariff exposure, and it maintains in-house R&D personnel, mold-processing equipment, assembly lines, laboratories and quality-control functions. Its representative products — including robot vacuum cleaners, household appliances, plastic tableware and smart sporting products — are best read as examples of its tooling, molding and assembly capability rather than as a fixed catalogue. See the company’s OEM/ODM服務 和 company profile for detail on process flow and capabilities.

Points to consider: an integrated partner makes most sense when your program involves multiple processes — tooling plus molding plus finishing plus assembly — or when you need engineering support rather than a simple build-to-print quote. If your requirement is a single simple part at the lowest possible unit price, a specialist molder focused on that part family may be a better fit. Buyers can review a representative program such as robot vacuum development and manufacturing to judge whether the engineering depth matches their product category.

2. Foxconn (Hon Hai Technology Group)

Best for: very large consumer electronics and computing programs where plastic parts must be produced in step with high-volume assembly.

What it does: Foxconn is one of the largest contract electronics manufacturers in the world, with plastics, tooling and mechanical parts produced inside the same group that carries out final assembly. Injection molding here supports enclosures, housings and internal components for consumer electronics and related devices.

Points to consider: this model is built around scale and integrated assembly schedules. It suits buyers with substantial, forecastable volumes and an existing product specification. Smaller brands, low-volume runs, or projects needing heavy early-stage design iteration are often better served by a specialised molder or an OEM/ODM partner that takes on concept development work.

3. Nolato

Best for: precision technical and medical components where tight tolerances, cleanliness and documented process control are the priority.

What it does: Nolato develops and manufactures polymer components and systems, with a strong presence in medical technology, automotive and consumer applications. The group operates internationally, including production in China.

Points to consider: precision medical work typically involves qualification cycles, material traceability and validation documentation, which adds time and cost. Buyers whose products are decorative consumer goods with looser tolerances may find this level of process control more than the project requires, and should compare against general-purpose consumer molders.

4. Jabil

Best for: regulated healthcare products and complex electromechanical assemblies that combine precision plastics with electronics.

What it does: Jabil is a global contract manufacturing organisation with precision plastics capability, including the healthcare-focused molding heritage of Nypro. Its China operations support both precision parts and full product assembly.

Points to consider: the value here is heavily tied to regulatory documentation, supply-chain control and global program consistency. For a straightforward industrial part or a small consumer accessory, a regional tooling and molding supplier is usually simpler to work with and more responsive to small changes.

5. Hongrita

Best for: export-oriented buyers needing mold making plus mid-to-high volume injection molding from a single Guangdong-based supplier.

What it does: Hongrita is a Dongguan-based mold maker and injection molder serving international customers across consumer, electronics and industrial applications. It covers mold design, tool manufacturing and subsequent production molding.

Points to consider: a tooling-first supplier is a good match when the part design is largely settled and the main goal is a robust mold plus reliable repeat production. If your project still needs product-level design work, electronics integration or final assembly, verify that those services are in scope before committing.

6. VEM Tooling

Best for: European and North American buyers who want Chinese tooling economics with project management conducted in a familiar working style.

What it does: VEM operates mold design and manufacturing in Xiamen with an engineering and project-management approach oriented toward export customers, covering tooling and related molding support.

Points to consider: managed tooling projects of this type are strongest where the tool is the deliverable and production may follow elsewhere. Buyers who need a long-term integrated manufacturing relationship including assembly and testing should confirm which downstream processes the supplier performs in-house.

7. Star Rapid

Best for: product teams moving from prototype to bridge production, especially those that value English-language engineering communication.

What it does: Star Rapid, based in Zhongshan, provides rapid prototyping, CNC machining and low-volume injection molding as part of an integrated prototyping workflow.

Points to consider: this model excels at design validation and small batches. Once a product moves into genuine mass production with tight unit-cost targets, many buyers transition to a high-volume molder or integrated OEM/ODM partner — sometimes with the same tooling, sometimes rebuilt.

8. WayKen Rapid Manufacturing

Best for: fast iterations, functional prototypes and pilot runs where speed matters more than unit cost.

What it does: WayKen, based in Shenzhen, offers rapid prototyping, CNC machining, and injection molding for low-volume and bridge production, with tooling built for validation purposes.

Points to consider: prototype-oriented tooling is not always built for long production life. If you intend to scale, clarify mold steel selection and cycle-life expectations, or plan to transfer the tool to a production molder.

9. Jason Mould

Best for: small to mid-size custom mold and molding projects with straightforward requirements.

What it does: Jason Mould is a Guangdong-based mold maker and injection molder serving custom projects, combining tool manufacture with production molding.

Points to consider: suppliers at this scale can be flexible and cost-effective on focused projects. Because equipment lists, capacity and quality systems vary considerably between suppliers of this size, request current evidence — machine tonnage range, measurement equipment, and references relevant to your part family — rather than relying on website content alone.

10. Ace Mold Company

Best for: consumer and industrial tooling programs sourced through Hong Kong with manufacturing in Guangdong.

What it does: Ace Mold works on mold design and manufacturing for consumer and industrial products, serving international clients from a Hong Kong commercial base with mainland production.

Points to consider: a Hong Kong commercial interface can simplify contracting and communication for some buyers. Confirm where value-add processes such as secondary operations, assembly and testing are performed, and whether production molding is handled in-house or coordinated through partners.

How to choose among injection molding companies in China

Match the supplier type to your program stage and product risk, rather than to the biggest name on a list.

• New product, unclear design: prioritise engineering and DFM capability, mold flow analysis and sample verification before tooling is cut.
• Design frozen, tooling needed: prioritise mold design quality, steel selection, cavity layout and tool life relative to your volume.
• Multiple processes involved: prioritise suppliers with in-house finishing, welding, printing, assembly and testing, so quality responsibility is not split across vendors.
• Regulated product: prioritise documented quality systems, material traceability and validation support.
• Multi-market supply: consider whether the supplier can produce in more than one country, which can matter for logistics and tariff planning.

Whatever the shortlist, request the same evidence from each candidate: a quotation breakdown covering tooling and piece price separately, a proposed project timeline with sample approval gates, the measurement and inspection equipment used, and the name of the engineer who will own your project. 聯繫我們 if you want to discuss a specific project scope with DAYIN.

Frequently asked questions

How much does plastic injection molding cost in China?

There is no meaningful average price, because cost is driven by part size and geometry, material, number of cavities, tolerance and surface finish requirements, tool life, annual volume and packaging or logistics. Tooling cost and piece price are usually quoted separately. Treat any figure quoted without reviewing your 3D files and volume forecast as an estimate only.

What lead time should I expect?

Lead time has two parts: tool design and manufacture, then trial molding, sample approval and production. Both depend on part complexity, mold design review cycles and how quickly samples are approved, so the timeline should be confirmed in writing at quotation stage rather than assumed.

Should I work with a molder, a mold maker, or an OEM/ODM partner?

A mold maker builds the tool; a molder runs production; an OEM/ODM partner takes responsibility for a broader slice of development and manufacturing, including design, engineering, secondary processes and assembly. The right choice depends on how much of the product development you want to retain in-house and how many processes you would otherwise have to coordinate yourself.

Is China still the right sourcing location?

China remains a deep, competitive base for tooling and injection molding, particularly for consumer products and integrated manufacturing. Some buyers now also evaluate Vietnam, India or domestic production for tariff, logistics or risk reasons. Suppliers with capacity in more than one country can reduce the disruption of switching, but they are not the only option — the decision depends on your product, volumes and market.

Bottom line

For high-volume consumer electronics, Foxconn’s integrated model is relevant. For precision medical and technical parts, Nolato and Jabil operate at the process-control end of the market. For export tooling with strong project management, Hongrita and VEM are established choices. For prototyping and validation, Star Rapid and WayKen are built around speed. Jason Mould and Ace Mold suit focused custom molding projects at different scales. And for buyers who want a single partner covering product development, precision tooling, injection molding, secondary processing, electronic assembly and finished-product manufacturing across China and Vietnam, DAYIN is a natural candidate to include in the same evaluation. The most reliable next step is to send the same RFQ package to three or four of these suppliers and compare engineering feedback, not just price.
