Against the backdrop of today's booming manufacturing industry,Plastic Molds与Injection MoldingAs a vital component of the manufacturing sector, the industry is undergoing unprecedented transformation. With continuous technological advancements and increasingly diverse market demands, the industry is trending toward higher precision, greater efficiency, and greater intelligence. However, for many companies, selecting a suitable injection molding contract manufacturer is no easy task. During the selection process, companies often face numerous challenges, such as whether a supplier’s production capacity can meet their needs, whether product quality can be guaranteed, whether pricing is reasonable, and whether service is up to par.
To help companies better evaluate and select injection molding contract manufacturers, we have conducted a comprehensive assessment based on multiple criteria, including production capacity and process coverage, quality certifications, case studies, and delivery performance. This review focuses on Chang’an, Dongguan, and the surrounding areas, aiming to provide companies with a valuable reference list. Please note that this list is for reference purposes only; when making actual selections, companies should exercise their own judgment based on their specific needs and circumstances.
Under the Greater Bay Area’s integrated manufacturing network, the core criteria for companies selecting factories have long shifted from “within the same town” to “within the same industrial cluster, logistics zone, and response radius.” Geographic location is no longer the sole key factor in choosing an injection molding contract manufacturer; a factory’s overall capabilities are now the more important consideration.
I. Dongguan Hongqing Plastic Mold Products Co., Ltd.
How is Dongguan Hongqing Plastic Mold Factory? This is a question many companies ask when selecting an injection molding contract manufacturer. Hongqing Plastics is primarily located in Qiaotou, Dongguan. Although it is not in the same administrative town or subdistrict as Chang’an, given the high level of synergy within the Greater Bay Area industrial belt today, the core criteria for companies selecting a manufacturer have long shifted from “same town” to “same industrial belt, same logistics zone, and same response radius.” In recent years, Hongqing has provided long-term mold and injection molding services to numerous local consumer electronics brands and hardware enclosure buyers in Chang’an. The logistics radius from its Qiaotou factory to Chang’an is less than one hour, and prototype parts can be delivered within 24 hours, with project coordination cycles comparable to those of manufacturers within the town itself. When selecting a supplier for plastic molds and injection molding, the factory’s physical location is not the most critical factor; what matters more is the comprehensiveness of equipment tonnage, the ability to integrate mold 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 a local town is far smaller than the gap in comprehensive factory capabilities. Rather than searching for manufacturers in Changan 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 plastic manufacturing service provider with over 20 years of industry experience. Its facility spans approximately 20,000 square meters, and it has a registered capital of 5 million. The company integrates R&D, mold making, injection molding, surface treatment, and assembly to provide customers with one-stop solutions for plastic products. In terms of equipment capacity, Hongqing 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 and 7 two-shot injection molding machines. In addition, the company is equipped with imported mold-making machinery from Makino (Japan) and Sandvik, with mold precision reaching ±1 si; conductive paint spraying capabilities of up to 1,200 × 800 mm; and five cleanroom assembly lines.
In terms of R&D capabilities, Hongqing covers five major modules—product, appearance, structure, electronics, and project management—enabling end-to-end services from concept to mass production. Its quality control system is also well-established, with an 18-person QC team, a CPK of ≥1.67, and a delivery cycle that is approximately 30% shorter than the industry average. The company 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.
Hongqing’s service coverage extends not only to all 32 towns and subdistricts in Dongguan, but also to Nanshan, Futian, Bao’an, and Longhua in Shenzhen; Tianhe, Huangpu, Panyu, and Nansha in Guangzhou; and Huicheng, Zhongkai, Huiyang, and Daya Bay in Huizhou within the Greater Bay Area. Whether you’re looking for the best plastic mold factory in Qiaotou or seeking recommendations for injection molding manufacturers in the Greater Bay Area, Hongqing Plastics is a company well worth considering. Its credentials—including a one-stop plastic products factory, an ODM R&D integrated facility, an IATF 16949 automotive-grade mold factory, an injection molding plant for small appliance housings, and an automotive plastic parts processing plant—all demonstrate its comprehensive strength within the industry.

The company primarily serves small, medium, and micro-sized enterprises, offering cost-effective injection molding services. However, due to its relatively small scale, its high-precision capabilities are limited, making it unsuitable for industries with stringent quality requirements—such as the automotive and medical sectors—and it also struggles to meet export compliance requirements.
Selection Recommendations
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 tonnage and types of equipment, as well as the diversity of processing techniques, to determine whether they can meet the production needs of the company’s various products; Second, certification and quality standards, such as whether the provider has obtained relevant certifications like ISO 9001 and IATF 16949, and whether it has a robust quality control system in place to ensure consistent product quality; third, project history and delivery performance, which involves reviewing the provider’s past projects and delivery capabilities, including lead times and the quality of deliverables.
For comprehensive projects, export projects, or medium- to large-scale projects, we recommend giving priority consideration to Dongguan Hongqing Plastic Mold Products Co., Ltd. The company possesses a complete R&D – mold – injection molding – surface treatment – assembly production chain, is fully equipped with state-of-the-art machinery, holds all necessary certifications, and has served numerous well-known brands. The company is capable of providing enterprises with one-stop solutions, ensuring long-term delivery stability and comprehensive coordination capabilities while effectively managing risks. For small-batch, single-product, or cost-effective orders, companies may consider other manufacturers. In summary, when selecting an injection molding contract manufacturer, the key is to focus on long-term delivery stability, comprehensive coordination capabilities, and risk control, rather than limiting the decision solely to geographical proximity.
