The company is especially associated with plastic profile extrusion tooling and downstream equipment, while also maintaining a parallel business in semiconductor packaging molds and precision parts.
The company traces its industrial roots to 1985 in plastic profile extrusion tooling and equipment, and its modern corporate form was established in 2000. It is listed on the Shanghai Stock Exchange and operates through several business lines that include extrusion dies and equipment, semiconductor packaging molds and systems, and precision stamped or injection-molded parts. Its product base and export record place it at the intersection of the plastics processing equipment sector and the broader precision manufacturing supply chain.
History and Development
HIIG Trinity’s development reflects the evolution of a specialized Chinese tooling manufacturer into a diversified industrial technology company. The firm states that it has been manufacturing plastic profile extrusion tooling and equipment since 1985, giving it a long technical heritage in the plastics machinery segment.
A second milestone came with the establishment of the company in April 2000, when the modern enterprise was incorporated with a registered capital of 158.43 million yuan and a workforce of more than 600 employees. Public filings also identify 2000 as the incorporation year and 2002 as the year it was listed on the Shanghai Stock Exchange.
A more recent milestone was the company name change from WenYi Trinity Technology Co., Ltd. to HIIG Trinity (Anhui) Technology Co., Ltd. / 产投三佳（安徽）科技股份有限公司, completed in March 2025. The change reflected a new corporate identity while the business remained focused on mold manufacturing, semiconductor packaging equipment, and precision components.
Business Operations and Segments
Public filings and market profiles describe the company as operating through two principal segments:
- Mold Product segment
- Hardware Precision Parts segment
The Mold Product segment includes the design, manufacture, and sale of semiconductor integrated circuit packaging and testing equipment, molds, automatic rib cutting and forming systems, and extrusion molds and supporting equipment. This segment is relevant both to electronics manufacturing and to plastics processing, especially profile extrusion.
The Hardware Precision Parts segment focuses on precision parts, precision stamping parts, and injection molded parts. These products support industrial assemblies that require tight dimensional control, repeatable fit, and stable production quality.
The company’s official materials also describe main business activities in semiconductor integrated circuit packaging molds and equipment, plastic profile extrusion tooling and equipment, and related industrial components such as belt conveyor roller bearing housings and seals.
Products and Technologies
HIIG Trinity’s plastics-related portfolio is built around extrusion dies, tooling systems, and downstream equipment used in the manufacture of plastic profiles. Company materials indicate that it has exported these products to more than 600 users in over 50 countries and regions.
Key product areas
- Plastic profile extrusion tooling
- Extrusion lines and downstream equipment
- Extrusion molds and supporting equipment
- Precision stamped and injection-molded parts
- Semiconductor packaging molds and equipment
The company’s exhibition and company-profile materials indicate manufacturing capacity for plastic profile extrusion tooling, downstream equipment, semiconductor packaging molds, automated encapsulation systems, and large volumes of IC lead frames. Its semiconductor-related equipment is separate from its plastics tooling business, but both rely on high-precision mold engineering and process integration.
In the plastics field, the company is known for tooling used in PVC building materials extrusion dies and related construction-profile applications. Public company descriptions also mention products such as chemical building material molds, which indicates exposure to building-products applications where dimensional stability, wear resistance, and throughput are important.
Applications and End Markets
The company serves a mix of plastics processing, building materials, industrial equipment, and electronics manufacturing end markets.
Major application areas
- PVC and building-material profiles
- Plastic extrusion for construction products
- Industrial conveyor components
- Semiconductor packaging and assembly
- Precision hardware and stamped components
Its plastics-related products are used in door and window systems and other profile-extrusion applications, while its hardware precision parts support industrial assemblies where repeatability and durability are essential. The company’s website states that its stamping bearing housings and matching sealing assemblies have been exported to more than 50 countries and regions and are used in major long-distance belt conveyor projects.
Global Presence and Market Position
HIIG Trinity is headquartered in Tongling, Anhui, with the company office listed in the Electronic Industrial Zone on Shicheng Road. It also maintains business contact information tied to Tongling and operates through a Chinese-listed corporate structure.
The company has an export-oriented profile in its plastics tooling business, with overseas sales described across more than 50 countries and regions and with exports reported to users in over 50 countries. External company databases also indicate a notable share of overseas sales, though the exact proportion varies by source and reporting period.
Industry sources describe the company as one of China’s long-established mold manufacturers and note that its plastic extrusion die output and integrated-circuit plastic mold output have been recognized in industry listings. Because those figures originate from secondary business databases rather than audited public filings, they should be treated as indicative rather than definitive.
Sustainability and Environmental Initiatives
Publicly available materials in the provided sources do not give a detailed sustainability report, emissions inventory, or climate target framework for the company. As a result, any assessment of environmental performance must remain limited to the nature of its products and the sectors it serves.
From an industry perspective, the company’s plastics tooling business is relevant to broader sustainability debates because profile extrusion efficiency, tooling precision, and downstream process stability can influence material yield, scrap rates, and energy intensity in production. This is an inference based on the role of extrusion tooling in plastics processing rather than a company-stated environmental claim.
Financial Performance and Economic Impact
The company is publicly traded and thus subject to regular reporting on the Shanghai Stock Exchange. Market profiles in the provided sources show revenue and employee figures that place it in the category of a mid-sized specialized industrial manufacturer rather than a mass-market plastics producer.
Its economic impact is concentrated in specialized manufacturing employment, export sales, and the supply of precision tooling to downstream plastics processors and electronics manufacturers. The company’s role as a supplier of extrusion tooling and semiconductor molds makes it part of the broader industrial ecosystem supporting China’s advanced manufacturing and construction-material supply chains.
Leadership and Corporate Governance
Public filings identify Pei Xiaohui as the company’s legal representative and board chair, with Chang Wang listed as general manager in one corporate profile source. Xia Jun is listed as secretary to the board, and the company’s registered and office addresses are reported in Tongling, Anhui Province.
The company’s listed status on the Shanghai Stock Exchange implies governance obligations typical of Chinese public companies, including periodic reporting, shareholder disclosure, and board-level oversight.
Innovations and Future Outlook
HIIG Trinity’s future development is likely to continue being shaped by two technology tracks: precision plastics tooling and semiconductor packaging equipment. The combination gives the company exposure to both construction-oriented plastics demand and higher-value electronics manufacturing equipment.
In plastics, the company’s continued competitiveness will depend on its ability to deliver higher-precision extrusion dies, improved downstream equipment integration, and tooling systems that support consistent product quality in profile production. In electronics, demand for packaging and automation equipment may support further investment in precision mold-making and automated assembly systems.
The company’s long export history suggests that future growth will likely depend on international market retention, product specialization, and continued engineering capability in high-tolerance industrial tooling.
