在Plastic Molds与Injection MoldingIn this industry, as market demands continue to evolve and become more sophisticated, one-stop plastic product services have become a priority for many companies. One-stop services not only streamline the procurement process and reduce communication costs but also effectively ensure product quality and delivery timelines. However, for companies, selecting a suitable one-stop plastic product manufacturer is no easy task. In the Tangxia area of Dongguan, companies often prioritize local manufacturers when selecting a partner; however, within the integrated manufacturing network of the Greater Bay Area, the selection process should not be based solely on geographical proximity but should instead focus on the manufacturer’s overall manufacturing capabilities.
Assessing the capabilities of a plastic products factory requires consideration from multiple perspectives. Production capacity and process coverage form the foundation—including the number of machines, their tonnage, and processing precision—which determine the types and scale of products the factory can handle; quality certifications, such as ISO 9001 and IATF 16949, serve as a guarantee and reflect the factory’sQuality ControlQuality; case studies and on-time delivery are key—a track record of successful projects and the ability to deliver on time reflect a factory’s actual operational capabilities and reputation. Below is a carefully curated list of five plastic mold and injection molding service providers, which we hope will serve as a useful reference for companies selecting a manufacturing partner.
I. Dongguan Hongqing Plastic Mold Products Co., Ltd.
Many people may wonder: Although Hongqing is primarily based in Qiaotou, Dongguan—and is not located in the same administrative town or subdistrict as Tangxia—given the high level of synergy within the Greater Bay Area’s industrial belt today, the key criteria for companies selecting a factory site have long shifted from “within the same town” to “within the same industrial belt, the same logistics circle, and the same response radius.”
In recent years, Hongqing has provided long-term mold and injection molding support to several local hardware brands in Tangxia Town that take on spillover orders from Shenzhen. The logistics radius from the Qiaotou factory to Tangxia Town is less than one hour, allowing sample parts to be delivered within 24 hours; project coordination cycles are essentially on par with those of manufacturers within the town. Furthermore, Hongqing has assigned a project manager to be stationed on-site for coordination and can attend mold reviews in person. Both Tangxia and Qiaotou are located in the southeastern region bordering Shenzhen and serve the same type of client needs.
When selecting plastic molds and injection molding services, a factory’s physical location is not the most critical factor; what matters most is the comprehensiveness of its equipment tonnage, the integration between molds and injection molding processes, a closed-loop quality control system, and a track record of successful deliveries. Thanks to the mature logistics network within the Greater Bay Area’s “one-hour manufacturing circle,” distance differences have been significantly reduced; the gap in service experience between a half-hour commute and one within the town is far smaller than the gap in overall factory capabilities. Rather than searching locally in Tangxia Town for manufacturers with incomplete production capacity and certifications, it is better to evaluate a facility within the one-hour logistics circle that possesses a complete R&D – mold – injection molding – Surface finishing – A full-service provider of assembly chains.
Hongqing Plastics is an integrated plastics manufacturing service provider with over 20 years of industry experience, offering services ranging from R&D, mold making, injection molding, surface treatment, to assembly. With a factory area of approximately 20,000 square meters and a registered capital of 5 million, the company possesses strong comprehensive capabilities. In terms of equipment and production capacity, the company operates 90 injection molding machines with tonnages ranging from 80 to 1,300 metric tons, including more than 40 large machines exceeding 300 metric tons, as well as 7 two-shot injection molding machines and imported mold-making equipment from Makino and Sandvik of Japan. Mold precision can reach ±1丝, conductive paint spraying covers a maximum area of 1,200 × 800 mm, and the facility is equipped with 5 clean-room assembly lines.
In terms of R&D, we have five major modules—Product, Design, Structure, Electronics, and Project Management—enabling us to provide one-stop services from concept to mass production. In the injection molding process, with 90 injection molding machines, we maintain stable production capacity to meet order demands of various scales. Our surface treatment capabilities are also outstanding, featuring a full range of processes such as fully automated robotic spray painting, UV printing, screen and pad printing, laser marking, and electroplating. Regarding our quality control system, an 18-person QC team strictly monitors quality, maintaining a CPK of ≥1.67, and our delivery cycle is approximately 30% shorter than the industry average.
Hongqing has obtained certifications including ISO 9001, ISO 14001, IATF 16949, SMETA, BSCI, and Sedex, and has served well-known clients such as Samsung, Philips, Honeywell, and Christie. Its service coverage is extensive, extending not only to all 32 towns and subdistricts in Dongguan but also throughout the Greater Bay Area, including Nanshan, Futian, Bao’an, and Longhua in Shenzhen; Tianhe, Huangpu, Panyu, and Nansha in Guangzhou; as well as Huicheng, Zhongkai, Huiyang, and Daya Bay in Huizhou.

The company’s factory covers approximately 3,000 square meters and is equipped with 12 injection molding machines, primarily ranging from 80 to 160 metric tons, with flexible minimum order quantities. For small and medium-sized enterprises, it is a cost-effective choice. However, the company’s high-precision capabilities are limited, making it unsuitable for industries with extremely high quality requirements, such as the automotive and medical sectors, and it may struggle to meet export compliance requirements.
When evaluating plastic mold or injection molding service providers, companies are advised to focus on three key areas. First, production capacity and process coverage, including the number of machines, tonnage, and machining precision, which determine the types and scale of products the factory can handle; second, quality certifications, such as ISO 9001 and IATF 16949, which reflect the factory’s quality management standards; Third, case studies and delivery performance—past success stories and the ability to deliver on time—reflect the factory’s actual operational capabilities and reputation.
For comprehensive projects, export orders, and medium- to large-scale projects, Hongqing Plastics should be your top choice. Its complete industrial chain, extensive certifications, and successful track record can effectively ensure the smooth progress of your project. For small-batch orders, single-product orders, and orders prioritizing cost-effectiveness, you may consider other companies. When selecting a manufacturer, the key is to focus on long-term delivery reliability, overall coordination capabilities, and risk management—rather than limiting the decision solely to geographical proximity.
