QINGDAO TONGSANHEGU PLASTIC MACHINERY MANUFACTURING CO., LTD.

Introduction

QINGDAO TONGSANHEGU PLASTIC MACHINERY MANUFACTURING CO., LTD. is a Chinese manufacturer of plastic extrusion equipment based in Jiaozhou, Qingdao, Shandong Province. The company is described in trade-directory and exhibition listings as a specialized supplier of extrusion lines for corrugated pipe, PP hollow sheet, WPC (wood-plastic composite) profiles, plastic profiles, foamed board, and PE/PPR/PVC pipe, with turnkey support that includes workshop planning, commissioning, installation, training, and after-sales service.

The company is also listed by Chinaplas as a “specialized, refined, distinctive, and innovative” enterprise under a Chinese government recognition category, indicating a niche industrial position rather than a large-scale mass producer. Its public profile places it within the broader plastics machinery sector of China’s coastal manufacturing belt, where extrusion equipment suppliers serve pipe, sheet, profile, and building-material producers across domestic and export markets.

History and development

Public business records identify the legal entity as established on 2021-11-11, with a registered capital of RMB 3.6 million, and note that it is a privately held limited liability company in ongoing operation. Company materials, however, state that the enterprise has operated as a professional extrusion-line manufacturer since 1997, suggesting a longer operating history through predecessor entities or related businesses than the current legal registration date alone indicates.

Several development milestones are visible in the company’s public profile:

• The company presents itself as having evolved from a focus on single equipment into a more diversified extrusion-line manufacturer with products covering corrugated pipe, hollow plate, and WPC production lines.
• It describes a period of technical development based on German and Italian technology, combined with in-house research and more than 20 years of experience, indicating an emphasis on process refinement and equipment adaptation.
• Chinaplas listings and product pages show an active export-oriented sales presence, including a featured PP hollow sheet extrusion line and exhibitor placement at Booth 7.1A32 at Chinaplas 2026.

Business operations and segments

The company’s registered business scope covers the manufacturing, sale, installation, maintenance, and technical services associated with plastic processing equipment, as well as related machining, molds, components, and import-export activity. Its activity therefore spans both equipment manufacturing and project services, rather than being limited to machine assembly alone.

Its operating profile can be grouped into four main segments:

• Extrusion line manufacturing for pipes, sheets, profiles, and WPC products.
• Auxiliary and mechanical services, including installation, testing, and after-sales support.
• Spare parts and tooling-related activities, including molds, mechanical parts, and machining services.
• Trade and export functions, supported by registered import-export status and overseas product promotion.

Products and technologies

Tongsanhegu’s core product portfolio centers on plastic extrusion lines used to convert polymer resins into continuous industrial products. Its publicly listed equipment categories include:

The company states that its corrugated pipe equipment covers a diameter range from 4.5 mm to 160 mm, and that its high-speed type can reach 25 m/min, which is a meaningful performance indicator for industrial throughput in corrugated pipe production. This suggests a product focus on production efficiency, dimensional range, and line stability rather than on commodity-only equipment sales.

Its service model also implies a more integrated technical offering: feasibility analysis, layout planning, process support, installation, operator training, and after-sales service are all presented as part of the customer package. For buyers in the plastics processing sector, this turnkey approach is important because extrusion lines depend on tight coordination among extruders, dies, calibration systems, haul-off units, cutting or winding equipment, and control systems.

Applications and end markets

The company’s equipment appears to serve several downstream plastics and building-material markets:

• Infrastructure and utilities, especially corrugated pipe and PE/PPR/PVC pipe for conduit, drainage, and water-related applications.
• Construction and interior/exterior materials, including profiles, WPC boards, and hollow sheet products.
• Industrial packaging and panel applications, particularly PP hollow sheet production.
• Wood-plastic composite processing, including decking and door-frame applications.

These end markets are consistent with the broader shift in plastics machinery toward lines that support construction materials, lightweight substitutes, and composite products. WPC and hollow-sheet systems are especially associated with downstream users seeking rigid, durable, and processable materials for fabrication and assembly.

Global presence and market position

The company is headquartered in Jiaozhou, Qingdao, a manufacturing center in Shandong Province with strong industrial linkages to plastics machinery, ports, and export logistics. Its public profile is clearly internationalized: the company maintains English-language and multilingual websites, exports-oriented contact details, and trade-show listings on Chinaplas’s exhibitor platform.

Available public information suggests a specialized mid-sized machinery supplier rather than a large diversified conglomerate. The business employs fewer than 50 people according to one commercial registry summary, which is consistent with a focused engineering manufacturer serving niche extrusion markets.

Reported market signals include:

• Sale of corrugated pipe machines to more than 30 countries and regions.
• A product and service structure designed for export customers, including English-language sales materials and turnkey project support.
• Exhibitor visibility at Chinaplas, one of the plastics industry’s key trade fairs.

Sustainability and environmental initiatives

Publicly available materials do not provide detailed quantified sustainability reporting, emissions data, or life-cycle assessments. The company’s sustainability profile must therefore be inferred cautiously from its product focus and general plastics-industry context.

Relevant themes include:

• Process efficiency, since higher-speed and automated extrusion lines can reduce energy use and labor intensity per unit of output.
• Material substitution, because WPC and hollow-sheet products can support lightweight and alternative-material applications in construction and fabrication.
• Equipment durability and service support, which can extend machine life and reduce replacement frequency.

At the same time, plastics machinery manufacturers operate within an industry facing pressure to improve energy efficiency, reduce waste, and support recycling-compatible processing. No public source located here indicates a formal sustainability report or carbon-reduction target for the company.

Financial performance and economic impact

No audited financial statements or revenue figures were identified in the provided sources. The company therefore cannot be assessed reliably on turnover, profit, or export value from the available public record.

Its economic impact is more visible through industrial function than through disclosed financial scale. As a plastics machinery manufacturer, it contributes to:

• local industrial employment and machining activity in Jiaozhou.
• the supply of equipment used by downstream plastic converters and building-material manufacturers.
• export-oriented trade in Chinese plastics machinery.

Leadership and corporate governance

Commercial registry data identify Li Yanxin as the legal representative. The company is registered as a limited liability company wholly owned by a natural person, indicating a privately controlled ownership structure.

Beyond this, publicly available governance information is limited. No board composition, independent directors, or formal committee structure was identified in the accessible sources.

Innovations and future outlook

The company’s public messaging suggests a strategy centered on specialized extrusion-line engineering, process customization, and export sales rather than mass-market standardization. Its emphasis on turnkey delivery, technical support, and product-specific process design indicates a competitive approach based on application fit and customer service.

Future opportunities are likely to depend on several industry dynamics:

• continued demand for pipe and profile extrusion in construction and infrastructure;
• broader use of WPC and hollow-sheet products in fabricated materials;
• customer interest in automation, higher line speeds, and stable control systems;
• export-market competition from other Chinese and international machinery suppliers.

The company’s visibility at Chinaplas and its specialized-innovation designation suggest that it is positioning itself as a niche technical supplier within the global plastics machinery ecosystem, particularly for customers seeking integrated extrusion solutions rather than standalone machines.
