Introduction
Shanghai Matsui Machinery Co., Ltd. (上海松井机械有限公司) is the mainland China subsidiary of Japan-based Matsui Mfg. Co., Ltd., a company founded in 1912 that specializes in auxiliary machinery for plastic processing and related industrial applications. Established in Shanghai in 1997, the company operates from Minhang District and maintains a multi-city sales, service, design, manufacturing, and development network across China, reflecting its role as a localized industrial platform within Matsui’s broader global organization.
In the plastics industry, Shanghai Matsui Machinery focuses on auxiliary equipment used around molding and extrusion lines, including dryers, temperature controllers, chillers, dosing and feeding systems, regrind and recycling units, mixers, and material handling equipment. Its customer base extends across sectors such as automotive, electronics, medical, optical, food, and general consumer goods, where process stability, contamination control, and energy efficiency are important production requirements.
The company is notable less as a commodity processor and more as a technology supplier that supports upstream and downstream plastics production by improving material preparation, thermal control, and recycling workflows. Public trade and business directories also indicate that it has established export activity and a distributed China presence, underscoring its integration into both domestic manufacturing chains and international equipment trade.
History and Development
Shanghai Matsui Machinery was established in 1997 as a wholly foreign-owned enterprise in Shanghai, building on the parent company’s long-standing expertise in plastic auxiliary machinery. The Shanghai base became part of Matsui’s broader China strategy after the parent company entered the Chinese market in 1993, when it began building local subsidiaries and service capacity in the country.
A second development milestone was the company’s expansion from a single Shanghai operation into a multi-branch China network, including offices and locations in Tianjin, Dalian, Suzhou, Nanjing, Hangzhou, Wenzhou, Wuhan, Qingdao, Shenzhen, and Xiamen, among others. This network indicates a business model centered on close technical support, commissioning, and after-sales service rather than purely centralized manufacturing.
A third milestone has been the company’s visible participation in industry exhibitions and technical forums, especially ChinaPlas-related events, where it has presented energy-saving dryers, stable temperature controllers, regrind recycling units, precise dosing units, and clean grinding proposals for sensitive applications such as optical and medical materials. This exhibition activity suggests a focus on application-specific engineering and process improvement rather than standard equipment sales alone.

Directory listings and trade references also associate the company with plastic extrusion equipment, mixer-extruders, disintegrators, and waste processing and recycling plant equipment. These references indicate that its portfolio extends beyond injection molding support into broader material preparation and recovery workflows.
Products and Technologies
Shanghai Matsui Machinery’s product range is centered on equipment that improves the quality and consistency of plastics processing. Public descriptions and industry listings identify the following principal categories:
| Product area | Typical function | Technical significance |
|---|---|---|
| Dryers | Remove moisture from resin before molding or extrusion | Helps prevent defects linked to hydrolysis, bubbles, and dimensional instability |
| Temperature controllers / mold temperature controllers | Maintain stable tool or process temperatures | Supports cycle consistency, surface quality, and repeatability |
| Chillers | Provide process cooling | Important for heat removal and line stability |
| Dosing units | Meter additives or colorants accurately | Improves formulation control and batch uniformity |
| Mixers and extruders | Blend materials and process compounds | Relevant to compounding and feed preparation |
| Regrind recycling units / grinders | Process scrap and runners for reuse | Supports internal recycling and material efficiency |
| Material conveying systems | Move resin automatically through a plant | Reduces manual handling and contamination risk |
Company and event materials emphasize energy-saving drying, stable temperature control, precise dosing, and clean grinding as recurring engineering themes. Industry commentary on Matsui’s temperature-control equipment describes features such as high-precision control, faster response, high-flow pumps, low-noise design, compact form factors, and multi-function control interfaces, suggesting a strong focus on process stability and operator usability.
The company’s clean grinding and recycling-oriented proposals are especially relevant to medical and optical manufacturing, where contamination control is critical and material reuse must be balanced against quality requirements. In this segment, the company appears to position equipment not simply as general-purpose machinery, but as part of a controlled production environment.
Applications and End Markets
Shanghai Matsui Machinery serves a broad set of end markets that rely on precision plastics processing:
- Automotive
- Electronics and electrical components
- Medical devices and medical packaging
- Optical parts
- Food-related equipment and packaging
- General consumer goods
- Industrial and chemical process applications
The company’s auxiliary machinery is particularly relevant in applications where resin condition, temperature stability, and contamination avoidance strongly affect final product quality. This is why its solutions are commonly associated with molded parts, precision components, and production lines that require repeatability and controlled material handling.
Global Presence and Market Position
Shanghai Matsui Machinery forms part of Matsui’s broader international network, which the parent company describes as spanning dozens of locations across multiple countries and regions. In China, the company serves as a regional hub for sales, service, design, manufacturing, and development, with offices distributed across key industrial clusters.
Trade and logistics databases show repeated export activity, indicating that the Shanghai entity participates in cross-border equipment supply, although publicly available data do not support a precise market share estimate. The company’s presence at major trade fairs such as Chinaplas also reinforces its visibility within the Asian plastics processing equipment market.
Sustainability and Environmental Initiatives
Shanghai Matsui Machinery’s sustainability profile is most visible in its emphasis on energy-saving drying, regrind recycling, and waste processing/recycling-oriented equipment. These product themes align with broader plastics-industry priorities around energy reduction, material efficiency, and circular use of polymer scrap.
The company’s clean grinding proposals for optical and medical applications indicate concern with contamination prevention and high-purity material recovery, which are important where recycled material must not compromise product performance. Its auxiliary systems can therefore be understood as enabling infrastructure for more efficient and potentially lower-waste plastics manufacturing, even though the company’s public materials do not provide detailed emissions or decarbonization targets.
Financial Performance and Economic Impact
Publicly available materials do not disclose Shanghai Matsui Machinery’s standalone revenue, profit, or order backlog in a way that would support reliable company-specific financial analysis. What is visible is its role as a mid-sized industrial employer and technical supplier with a durable presence in China’s machinery sector.
Economically, the company contributes by supporting plastics processors with equipment that can improve throughput, reduce scrap, and stabilize production. Its localized service network also has broader value in reducing downtime and in making advanced process-control systems accessible to manufacturers across regional clusters.
