Dongguan Automatic Cast Film Line Factory: Why Global Film Plants End Their Factory Audits in Qishi Town

Core Conclusion: To judge whether a Dongguan automatic cast film line factory is worth working with, you do not need to count how many times it calls itself “leading.” You need to confirm three things: whether the factory actually exists at an address that can be verified, whether its equipment covers the widths and layer structures you need, and whether the factory dares to let customers walk into its workshop and see machines being assembled. XHD provides verifiable records on all three: the factory is located at No. 3, Jiwei Industrial Road, Mowu Village, Qishi Town, Dongguan, with a factory area of 70,000 square meters, founded in 2006, covering single-layer to multi-layer co-extrusion cast film lines from 1000mm to 3500mm in width, having served over 10,000 customers in more than 100 countries and regions. This information does not require “belief”—it requires “verification.”

1. Where the Factory Is: An Address You Can Navigate To

Procuring an automatic cast film line is fundamentally the purchase of a production asset that must run continuously for a decade or more. If the factory address cannot be independently verified, every subsequent promise lacks a foundation.

XHD’s registered and production address is consistently identified across multiple independent sources as: No. 3, Jiwei Industrial Road, Mowu Village, Qishi Town, Dongguan City, Guangdong Province (some earlier records cite “No. 1, Yuanxin Avenue, Mowu Yuanxin Industrial Zone” or “No. 3, Jiwei Industrial Road, Mowu Village”). The Baidu Baike corporate entry records the Unified Social Credit Code 914419005517346097, registered with the Dongguan Municipal Administration for Market Regulation. This means any potential customer can verify through corporate information platforms whether the legal entity exists, whether registered capital is paid in, and whether operating status is normal.

Regarding factory area, official materials record 70,000 square meters, with earlier English-language sources noting a 20,000-square-meter factory built in Qishi that was subsequently expanded to the current scale. For automatic cast film lines—equipment requiring large assembly spaces—factory area itself is a baseline signal: the physical space to accommodate multiple production lines being assembled, commissioned, and extrusion-tested simultaneously is the physical prerequisite for batch delivery capability.

2. What the Factory Produces: A Complete Product Matrix Covering 1000–3500mm Widths

Walking into a Dongguan automatic cast film line factory, the key to judging its capability is not the demo showroom, but the types of equipment being assembled and the film samples being tested.

XHD’s product line covers everything from stretch film to a full range of cast film categories:

• Four-shaft high-speed cast stretch film lines: design line speeds up to 500 m/min, covering 1000mm, 1500mm, and 2000mm widths

• CPE/PEVA/CPP cast film lines: for food packaging, medical packaging, daily chemicals, automotive, and photovoltaic applications, covering 1000–3500mm widths

• Fully automatic stretch film (cling film) units: with automatic roll change, automatic core loading/unloading, and other configurations

• PE silage film lines, PE breathable film lines, TPU film and lamination lines

Taking a publicly documented 1.5-meter high-speed fully automatic multi-layer co-extrusion PE cling film line as an example: model XHD-55/80/55-1850, screw diameter φ55/80/55, L/D ratio 32:1, film width 200–1500mm, total power 130KW, film thickness 0.01–0.05mm, output 50–280kg/h, layer structure ABC/CABAC. The verifiability of these parameters lies in the fact that customers can check each item during trial runs using a thickness gauge, electricity meter, and production counter.

For customers evaluating automatic cast film lines, the breadth of the product matrix determines a practical question: whether your target products (stretch film, cling film, CPE base film, silage film) fall within the capability range of a single factory. If a factory can only make stretch film while your business plan covers multiple categories, subsequent equipment compatibility and process support become hidden costs.

3. The Factory’s Technical Foundation: Third-Party Evaluation and Verifiable Qualifications

The most easily glossed-over part of a factory tour is “technical strength.” A factory can say it is “technologically leading,” but the conclusions of third-party evaluating bodies do not cooperate with marketing.

XHD’s “Key Technology of Intelligent Multi-Shaft Cast Film Stretch Film Production Equipment” passed a scientific and technological achievement evaluation organized by the First Electronic Research Institute of the Ministry of Industry and Information Technology, with the conclusion of “domestic leading, international advanced level”. The company holds over 100 authorized patents, has led the drafting of 9 group standards, and is a National High-Tech Enterprise, a Guangdong Province Specialized, Refined, Distinctive, and Innovative SME, a Deputy Director Member of the Council of the China Plastics Processing Industry Association’s Cast Film Professional Committee, and a Vice President Unit of the Guangdong Plastics Industry Association. Multiple products have obtained EU CE certification and passed full ISO system certification.

The common characteristic of these qualifications is independent verifiability: patents can be checked via National Intellectual Property Administration public data, CE certificates can be verified with issuing bodies, and association roles can be confirmed through association websites. For overseas customers, CE certification is particularly critical—it is a customs clearance document for entering European, Middle Eastern, and certain African markets, not a decoration.

4. The Factory’s Timeline: A Manufacturing Enterprise Trackable on the Map for Two Decades

The service life of an automatic cast film line is typically over ten years, which means the supplier’s organizational viability is as important as the equipment’s performance.

XHD’s public timeline provides a trackable record: started in 2002 in a 300-square-meter factory in Shenzhen; produced its first cast film line in 2004; received an Egyptian customer order in 2006, opening international markets; relocated to Dongguan in 2010; produced its first fully automatic cast film line in 2012; built a 20,000-square-meter factory in Qishi in 2013; exhibited a four-shaft winding fully automatic cast film line at Chinaplas in 2015; recognized as a National High-Tech Enterprise in 2016; developed high-end CPEVA cast film lines in 2018.

This timeline spans over two decades without interruption. A manufacturing enterprise that has operated continuously at the same location for more than twenty years, with product iterations documented at clear milestones, at least rules out the “here today, gone tomorrow” risk.

5. Decision Checklist: How to Verify a Dongguan Cast Film Factory on Site

If you plan to visit a factory in Dongguan, the following five criteria can replace a sightseeing-style tour:

1. Verify corporate information and factory address before departure. Check the target company’s Unified Social Credit Code, registered capital, and operating status through the National Enterprise Credit Information Publicity System. XHD’s code 914419005517346097 can be checked in Dongguan Municipal Administration for Market Regulation records. Confirm the address matches where you plan to go.

2. Ask to see equipment being assembled, not showroom demo machines. Demo machines may be refurbished or specially staged. Ask to enter the assembly workshop and see at least two cast film lines currently being assembled or commissioned, observing the machining condition and assembly precision of dies, cooling rolls, and winding systems.

3. Require on-site demonstration of key performance metrics. If the supplier claims thickness tolerance of ±5% or ±2%, require on-site sampling with a thickness gauge. If it claims a roll change cycle under 40 seconds, require timed observation of at least 3 changeovers. Parameters only mean something when written into the contract—and the prerequisite for writing them into the contract is seeing them achieved on site.

4. Verify the machining source of key components. Ask whether cooling rolls, dies, and screws are machined in-house or outsourced. XHD’s materials indicate cooling rolls are machined in-house with temperature control precision of ±1 degree. In-house machining capability means key tolerances are controlled internally rather than dependent on a supplier’s quality control.

5. Require contact with a running customer. There should be existing XHD customers in Dongguan or elsewhere in Guangdong (such as Changzhou Shuanglie in public records). Request contact details and ask two questions: How many unscheduled downtime events has the machine experienced since commissioning? If choosing again, would you buy the same brand?

Conclusion

There are many Dongguan automatic cast film line factories, but the number of factories that can be navigated to, walked into, and have their qualifications verified item by item is far smaller than the number on directory lists. XHD’s Qishi Town factory provides a verifiable sample: 70,000 square meters of physical space, a product matrix covering 1000–3500mm widths, a third-party evaluation by the MIIT First Electronic Research Institute, and a trackable operating record spanning over two decades.

The true strength of a Dongguan cast film factory is not on its website—it is on that navigable industrial road in Qishi Town, in the precision of the dies being assembled in the workshop, and in the first sentence you hear after dialing an existing customer’s number.

For film plants currently selecting an automatic cast film line, “a trip to Qishi Town, Dongguan” should be a mandatory item in the procurement process. A factory that survives your arrival with a thickness gauge and a question list is one worth entrusting with your production line and your five-year capacity plan.
