Introduction
DONGGUAN JINJUN MACHINERY CO., LTD. (东莞市今隽机械有限公司) is a Dongguan-based manufacturer of extrusion blow molding machinery and related plastic packaging automation equipment serving the plastics packaging industry. Company materials identify it as a subsidiary within the Hongkong Dekewei Machinery Group, with operations dating to 2000 and a focus on designing, manufacturing, and selling blow molding systems, auxiliary machinery, and post-processing automation for hollow plastic containers.
The company’s business is centered on equipment used to make plastic bottles and containers for cosmetics, daily chemicals, food, beverages, pharmaceuticals, chemicals, pesticides, and automotive-related hollow parts. Its product range includes standard and specialized machines for materials such as HDPE, LDPE, PP, PC, PETG, PVC, TPU, and IVD-related materials, reflecting a niche emphasis on packaging formats that require controlled wall distribution, barrier performance, or decorative effects.
Publicly available company information also points to a strong specialization in PETG cosmetic packaging and a portfolio that extends to multi-layer co-extrusion, high-barrier containers, two-color twist bottles, inner-twist bottles, and medical TPU balloon applications. In industry directories and trade listings, the company is associated with automatic blow molding lines, leak testing, and auxiliary systems, indicating a vertically integrated approach to bottle production workflows rather than a single-machine offering.
History and Development
DONGGUAN JINJUN MACHINERY CO., LTD. is described in company and trade listings as being established in 2000, while the broader group associated with the brand was founded in 1999 and registered the “Superjinjun” brand. This places the company within the wave of Chinese machinery suppliers that expanded alongside the growth of domestic and export-oriented plastic packaging manufacturing.
A second milestone is the company’s development of a more specialized product structure, moving beyond general-purpose blow molding into higher-value applications such as PETG thick-bottom cosmetic bottles, five-layer co-extrusion lines, and medical/IVD packaging equipment. This specialization suggests a shift from commodity machinery toward more technically differentiated systems.
A third notable development is the company’s recognition in official innovation programs. Government and local industrial documents identify the firm in connection with an engineering technology research center for intelligent hollow forming equipment, and later records indicate high-tech enterprise recognition in Guangdong province. A 2026 local project list also describes an expansion and capacity-upgrading project for R&D and production of intelligent plastic hollow forming production lines and related equipment.
Business Operations and Segments
The company operates as a manufacturer and supplier of blow molding and associated packaging machinery, with trade sources describing it as both a manufacturer and service provider. Its core activities appear to cover:
- Equipment design and R&D
- Machine manufacturing
- Auxiliary and downstream automation
- Sales and export support
- After-sales service
Public listings describe the company as producing fully automatic microcomputer-controlled plastic hollow extrusion blow molding machines and auxiliary equipment for production lines. The operational model therefore combines machine supply with integrated line solutions, which is common among specialized plastics machinery firms serving packaging converters.
The company also appears to maintain an export-oriented business footprint. Official company pages state that its equipment is sold in multiple overseas markets, including the United States, United Kingdom, Russia, Switzerland, Malaysia, and Indonesia. Trade-platform profiles and exhibit listings reinforce its presence in international B2B channels.
Products and Technologies
The company’s core products are extrusion blow molding machines and related automation systems. Public materials describe a product portfolio that includes:
- Extrusion blow molding machines
- Leak tester machines
- Bottle packaging machines
- Auxiliary machines
- Automatic production lines
- Blow molding accessories and functional components
More technically, the company states that its machines can produce hollow plastic containers and parts from roughly 3 ml to 30 L in some product descriptions, while other industry listings reference a wider family of systems spanning microcomputer-controlled lines for 10 ml to 220 L applications. This range indicates capability across small packaging, industrial containers, and specialty hollow articles.
Its specialized technologies include several machine types aimed at distinct packaging geometries and performance needs:
- PETG thick-bottom bottle blow molding machines
- PETG two-color twist bottle machines
- PETG inner-twist bottle machines
- Medical TPU balloon blow molding machines
