Introduction
SHENZHEN RUNTUO MACHINERY CO., LTD. (深圳市润拓机械有限公司) is a Chinese manufacturer focused on micro and small electric injection molding machines, with an emphasis on precision molding, energy-efficient operation, and compact machine footprints for specialized plastics applications. The company is based in Bao’an District, Shenzhen, Guangdong, and it presents itself as a supplier of molding systems for sectors such as medical devices, IT and communications, and micro-mechanism parts, which typically require high repeatability and fine process control.
Within the plastics machinery ecosystem, Runtuo occupies a niche centered on low-tonnage injection molding equipment rather than large-scale general-purpose molding lines. Its product range is described as spanning 5 tons to 35 tons of clamping force, including all-electric small horizontal injection molding machines, electro-hydraulic hybrid micro/small horizontal machines, and electro-hydraulic hybrid small vertical machines. The company also markets auxiliary configurations such as servo rotary tables for multi-color or multi-material molding, indicating a specialization in compact, precision-oriented production setups.
History and Development
Runtuo states that it has been engaged in the research and manufacture of micro injection molding equipment for nearly ten years, building experience from “tens of thousands” of application instances in precision-oriented production fields. This suggests a development path shaped by iterative engineering for small-part molding rather than by broad diversification into large industrial platforms.
A few concrete milestones are visible in the company’s public materials:
- It has established a product line covering 5T–35T micro and small electric injection molding machines, including both all-electric and hybrid architectures.
- It reports sales coverage across 20+ provinces and municipalities in China, indicating a domestic commercialization phase beyond early prototype development.
- It has been recognized on Chinaplas’s exhibitor platform as a “specialized, sophisticated, distinctive, and innovative” enterprise designation in China’s policy vocabulary, underscoring its positioning as a precision manufacturing specialist rather than a mass-market supplier.
The company’s marketing materials also indicate an ambition to expand the application of its “smart injection” equipment beyond the domestic market, although no public filing in the provided sources quantifies export volume or overseas installed base.
