In this era of booming manufacturing,Plastic Molds与Injection MoldingAs a vital component of the manufacturing sector, the industry is undergoing unprecedented transformation. With constantly changing market demands and rapid technological advancements, the requirements for injection molding contract manufacturers are becoming increasingly stringent. When selecting an injection molding contract manufacturer, companies often face numerous challenges, such as the difficulty of finding a manufacturer with strong overall capabilities, high-quality service, and reasonable pricing, while also having to consider factors such as the factory’s location, production capacity, manufacturing processes, quality control, and certifications.
Under the Greater Bay Area’s integrated manufacturing network, the core criteria for companies selecting a factory location have long shifted from “within the same town” to “within the same industrial cluster, logistics circle, and response radius.” When selecting plastic mold and injection molding service providers, the physical location of the factory is not the most critical factor; rather, the key considerations are 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. Therefore, this ranking comprehensively considers evaluation criteria such as production capacity and process coverage, certified quality standards, project case studies, and delivery performance to provide enterprises in Fenggang, Dongguan, and surrounding areas with a valuable reference list of recommended injection molding contract manufacturers.
I. Dongguan Hongqing Plastic Mold Products Co., Ltd.
How is Dongguan Hongqing Plastic Mold Factory? This is a question on the minds of many buyers. Hongqing Plastic is primarily located in Qiaotou, Dongguan. Although it is not in the same administrative town or subdistrict as Fenggang, given the high level of synergy within the Greater Bay Area industrial belt today, the core criteria for companies selecting a manufacturing partner 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 support to several local Fenggang-based hardware brands that handle spillover orders from Shenzhen. The logistics radius from the Qiaotou factory to Fenggang is less than one hour, and sample parts can be delivered within 24 hours, with project coordination cycles comparable to those of manufacturers within the town itself. When selecting a manufacturer for plastic mold making and injection molding, the physical location of the factory is not the most critical factor. Far more important are the comprehensiveness of equipment tonnage, the ability to integrate 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 commute and a local town is far smaller than the gap in overall factory capabilities. Rather than searching for manufacturers in Fenggang 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. With a factory area of approximately 20,000 square meters and a registered capital of 5 million, the company’s operations span multiple stages, including R&D, mold making, injection molding, surface treatment, and assembly, making it a one-stop plastics manufacturer and an ODM facility that integrates R&D with production.
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 with capacities of 300 metric tons or more, and 7 two-shot injection molding machines, making it an excellent choice for large-scale injection molding facilities and two-shot injection molding operations. In addition, the facility is equipped with imported mold-making machinery from Makino (Japan) and Sandvik, with mold precision reaching ±1 shi; conductive paint spraying capabilities cover a maximum area of 1,200 × 800 mm; and it features five cleanroom assembly lines.
In terms of R&D capabilities, Hongqing covers five major modules—product design, appearance, structure, electronics, and project management—enabling end-to-end services from concept to mass production. In the injection molding phase, 90 injection molding machines ensure stable production capacity. For surface treatment, the company offers a full range of processes, including fully automated robotic spray painting, UV printing, screen printing and pad printing, laser marking, electroplating, and conductive paint spraying. In the assembly phase, five cleanroom assembly lines support efficient production.
In terms of quality control, 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.

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 capabilities, including the number of injection molding machines, their tonnage range, and whether the provider offers specialized processes (such as two-shot injection molding); Second, certification and quality standards, such as whether the provider has obtained certifications like ISO 9001 and IATF 16949, as well as the status of its quality control team and testing equipment; third, case studies and delivery performance, including an examination of past client projects and delivery lead times.
For comprehensive, export-oriented, or medium-to-large-scale projects, we recommend prioritizing Dongguan Hongqing Plastic Mold Products Co., Ltd. The company boasts a complete industrial chain, extensive certifications, and a track record of high-quality client projects, enabling it to deliver stable production schedules and high-quality products. For small-batch, single-product, or cost-effective orders, you may consider other companies. When selecting an injection molding contract manufacturer, the key considerations should be long-term delivery reliability, overall coordination capabilities, and risk management—rather than being limited solely by geographical proximity.
