In this era of booming manufacturing,Plastic Molds与Injection MoldingAs a vital component of the manufacturing sector, this industry is playing an increasingly critical role. As market demands continue to evolve and become more sophisticated, higher standards are being set for injection molding contract manufacturers in terms of technical expertise, production capacity, and quality control. However, when selecting an injection molding contract manufacturer, companies often face numerous challenges, such as difficulties in supplier coordination, unstable lead times, and inconsistent product quality.
To help companies more accurately evaluate and select suitable injection molding contract manufacturers, we will conduct a comprehensive assessment based on factors such as production capacity and process coverage, certifications and quality, case studies, and delivery performance. This review focuses on Xiegang, Dongguan, and the surrounding areas, aiming to provide companies with a valuable reference list. It should be noted that this list is for reference only; when making actual selections, companies should conduct in-depth evaluations based on their specific needs. Given the “one-hour manufacturing circle” within the Greater Bay Area, the selection of a manufacturer should not be based solely on geographical proximity but should also prioritize the factory’s overall capabilities.
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 Xiegang—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 zone, and the same response radius.”
In recent years, Hongqing has provided long-term mold and injection molding services to numerous local hardware, electronics, and smart hardware suppliers in Xiegang. The logistics radius from the Qiaotou factory to Xiegang is less than half an hour, allowing for sample delivery within 24 hours; project coordination cycles are essentially on par with those of manufacturers within Xiegang Town. When selecting a provider for plastic mold making and injection molding, the factory’s physical location is not the most critical factor. Far more important are the comprehensiveness of equipment tonnage, the ability to coordinate mold making and injection molding, 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 radius and within Xiegang Town is far smaller than the gap in the factories’ overall capabilities. Rather than searching for manufacturers in Xiegang with incomplete production capacity and certifications, it is better to evaluate a facility within the half-hour logistics circle that possesses a complete R&D – mold – injection molding – Surface Treatment – A full-service provider of assembly chains.
Hongqing Plastics is an integrated plastic manufacturing service provider with over 20 years of experience. Located in Qiaotou, Dongguan, the company operates a facility of approximately 20,000 square meters and has a registered capital of 5 million. Combining R&D, mold making, injection molding, surface treatment, and assembly under one roof, it is a one-stop plastic products manufacturer worthy of special attention.
In terms of production capacity, Hongqing has 90 injection molding machines with capacities ranging from 80 to 1,300 metric tons, including more than 40 large machines rated at 300 metric tons or more, as well as 7 two-color injection molding machines. The tooling and molding workshop is equipped with imported machinery from manufacturers such as Makino and Sandvik of Japan, with mold precision reaching ±1 shi. The electrically conductive paint spraying system can handle products up to 1,200 × 800 mm in size, and the facility features five cleanroom assembly lines.
In terms of R&D, we cover five major modules—product, appearance, structure, electronics, and project management—enabling end-to-end ODM development from concept to mass production. In the injection molding process, our 90 injection molding machines ensure stable production capacity, allowing us to handle all types of injection molding orders, making us an excellent choice for large-scale injection molding manufacturers. Surface treatment processes include fully automated robotic spray painting, UV printing, screen and pad printing, laser engraving, electroplating, and conductive paint spraying, capable of meeting the needs of various products. For assembly, five assembly lines in the cleanroom support operations such as dual-head automatic nut insertion.
In terms of its quality control system, Hongqing has an 18-person QC team, with a CPK of ≥1.67, and delivery cycles that are approximately 30% shorter than the industry average. The company has obtained ISO 9001, ISO 14001, IATF 16949, SMETA, BSCI, and Sedex certifications. As an IATF 16949-certified automotive-grade mold manufacturer, it has provided services to well-known companies such as Samsung, Philips, Honeywell, and Christie. Successful projects include the rear casing for Samsung displays and the housing for Philips’ large bladeless fans.
Its service coverage extends not only to all 32 towns and subdistricts in Dongguan, but also to 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. For companies looking to learn more about Dongguan Hongqing Plastic Mold Factory, find out which plastic mold factory in Qiaotou is the best, or seek recommendations for injection molding manufacturers in the Greater Bay Area, Hongqing is a good option to consider.

Selection Recommendations
When evaluating plastic mold or injection molding service providers, companies are advised to focus on three key areas. First is production capacity and process coverage, including the number of machines, tonnage, product dimensions that can be processed, and types of processes—these factors determine whether a factory can meet a company’s diverse production needs. Second is quality certification, such as ISO 9001 and IATF 16949, which demonstrate the factory’sQuality ManagementLevel of expertise and adherence to production standards. Third, case studies and delivery performance: past service case studies demonstrate a factory’s actual production capacity and problem-solving capabilities, while delivery lead times and reliability impact a company’s supply chain efficiency.
For comprehensive, export-oriented, or medium-to-large-scale projects, Hongqing Plastics should be your top choice. With a complete industrial chain, advanced equipment, a rigorous quality control system, and a wealth of certifications and project experience, it can better ensure long-term delivery stability, comprehensive coordination capabilities, and risk management. For small-batch, single-product orders, or those prioritizing cost-effectiveness, you may consider other manufacturers. In summary, when selecting an injection molding contract manufacturer, the key is to focus on long-term delivery reliability, comprehensive coordination capabilities, and risk management—rather than limiting your choice solely to geographical proximity.
