In 2003, Guilin Rubber Machinery Factory was selected as a pilot unit for national enterprise innovation and patent development. By 2004, it was recognized as a State-Level Enterprise Technology Center, marking a significant milestone in its technological advancement. In 2006, the factory made global headlines when "European Rubber Magazine," one of the most respected publications in the rubber industry, ranked Guilin Rubber Machinery Plant among the top seven manufacturers of rubber machinery worldwide. These achievements are just a glimpse of the numerous accolades the company has earned over the past few years. Over the last three years, the company's production scale has grown dramatically, from nearly RMB 100 million to over RMB 500 million. This growth has positioned Guilin Rubber Machinery as the world’s largest vulcanizer manufacturer and placed it among the top ten global rubber machinery companies. The company has also contributed significantly to national science and technology initiatives, with 10 products included in the national major new product plan and nearly 50 patents registered. Behind this success is a simple yet powerful driving force: innovation. To build a strong foundation for sustainable growth, the company has embraced innovation in talent management. As market competition intensifies, attracting and retaining skilled professionals has become critical. In response, Guilin Rubber Machinery broke away from traditional state-owned enterprise practices, transforming talent development into a systematic initiative. Open recruitment is now the standard for selecting middle-level managers and project leaders, ensuring that the best people are in the right roles. Employees are encouraged to continuously learn through a combination of structured training and a culture that values knowledge and skill. The company also implements a three-year rotation program to ensure employees gain diverse experience. In terms of performance, high rewards come with high expectations—successful managers can receive car bonuses worth tens of thousands of yuan, while underperformance may result in reduced benefits. Product innovation has been central to the company’s competitive edge. Positioned as a leading manufacturer of tire vulcanizing machines, the factory focuses on “curing,” “precision,” and “scale” to develop high-value, multi-species products. It has successfully launched a full range of vulcanizers from 1050 to 3000 models, breaking previous limitations and meeting custom orders efficiently. In 2004, it achieved the first step in its five-phase development plan by introducing China’s first-class curing press. The goal now is to reach international benchmarks and produce world-class products. In addition to vulcanizers, the company has expanded into other rubber machinery sectors, including radial tire production. Quality remains a top priority, with rigorous global procurement strategies and advanced PDM (Product Data Management) systems to ensure zero defects in design. Marketing innovation has played a key role in the company’s transformation. By adopting a customer-centric approach, the factory has integrated sales, marketing, and after-sales services into a unified system. It has shifted from a purely domestic focus to a global mindset, aligning product development and sales with international standards. Chinese-American managers have been hired to lead overseas operations, and service networks have been established in the U.S., Europe, and Japan. In 2000, the company made a breakthrough by supplying hydraulic vulcanizers to Michelin, France’s largest tire company, ending China’s “zero export” record for such equipment. Today, it supplies over 100 units to Michelin and has become a long-term partner. This success led to the widespread adoption of hydraulic vulcanizers in Chinese tire factories. In 2001, the company’s vulcanizing machine passed TUV certification, opening doors to the European market. Among the world’s top 75 tire companies, 17 use Guilin’s products, and 9 of the top 10 tire companies are among its clients. As of 2005, the factory had exported nearly 400 vulcanizers, earning over $50 million in foreign exchange. In 2006, it secured $16 million in export orders, with exports accounting for one-third of annual revenue.

Extrusion Single Screw Barrel

Single screw extrusion uses one screw within a cylindrical barrel to continuously push plastic through a constant profile die. Production rate is typically measured in mass per hour (lb/hour or kg/hour) and is controlled by the screw speed of the machine.

Most extruder products are produced using single screw extrusion. Parts such as window frames, house siding, and weather stripping, which have a constant profile, are generally produced by means of single screw extrusion. Due to such factors as the melt swelling as it exits the die, the die design for an extruder is critical. Great complexity is sometimes needed with an extrusion die in order to gain the correct profile.

The two largest industries for extrusion are pipe and tubing extrusion and film and sheet extrusion. There are many other industries that use extrusion to create their products though. Fiber extrusion, for clothing, coating extrusion, and blown film extrusion are just a few of the others.
