2. Top 10 Medical Plastic Injection Molding Manufacturers in China

The key information about the top 10 medical plastic injection molding manufacturers in China is listed below.

Top 1: Holly Plastic Parts Co., Ltd

Holly Plastic Parts Co., Ltd., established in 2000, built a solid manufacturing foundation with its strength in precision plastic injection molding. With a production plant that can accommodate over 20 injection molding machines with tonnages ranging from 50 to 500 tons, the company is at the top of production flexibility. This is complemented by a Class 100,000 cleanroom, which is mandatory for production of medical and high-precision components. The arrangement allows them to produce in excess of 5 million plastic parts on a consistent monthly basis, covering high-volume as well as complex low-volume projects.

The company provides a single-source, total service that streamlines the entire production process for its clients. Their integrated solutions include in-house mold making and design to offer high-quality tooling, and then full-scale production, assembly, and packaging. All of this end-to-end service is augmented by strict quality control processes based on Coordinate Measuring Machines (CMM) and other advanced metrology devices to ensure that every component is of very tight specifications. One of their best service offerings is their experience handling a large range of engineering-grade and medical-grade plastic materials, which makes them an ideal choice for high-volume companies.

One interesting client project that showed off their skills involved one where they collaborated with a leading European diagnostic device company. Holly Plastic Parts was commissioned to produce a critical, complex housing for a portable blood analyzer. The application required tight tolerances of ±0.02mm and flame-resistant, bio-compatible material. Through their full-service capability, they designed and built a multi-cavity tool in-house and managed the entire production through to end assembly. The achievement of this project, now producing over 500,000 pieces annually in terms of order quantity, attained a long-term partnership and demonstrated Holly Plastic Parts’ ability to deliver stable, high-precision solutions to the global medical community.

Top 2: Hochuen Medical Company

Commenced in 2015, Hochuen Medical (HK) Company Limited became an authority of high-precision medical plastic injection molding very soon. The company manufactures from a new facility with over 15 of the latest injection molding machines with a focus on precision machines with clamping forces below 350 tons, making them precise medical part machines. One of their support pillars is a dedicated Class 10,000 cleanroom facilitating the strict hygiene and contamination control requirements for Class II and III medical devices. This setup enables them to manage a broad production portfolio, with validation runs and mass production being managed effectively.

Hochuen Medical is also very good at providing a seamless, one-stop process from concept to delivery. Their core strength is in advanced mold design and production, often with micro-molding and multi-material use. They offer extensive validation services such as IQ, OQ, and PQ protocols along with full material traceability in accordance with FDA and ISO 13485 regulations. The chief service advantage is that they are highly flexible to manage low-to-medium volume production lots, hence a great partner for start-ups as well as established companies launching niche or high-margin medical devices.

One of their finest case studies that illustrates their capability was the time they partnered with an American biotech firm that was constructing a new, single-use cartridge for a molecular diagnostics instrument. The part featured micro-fluidic channels of tolerance within ±0.015mm and required the use of certified medical-grade cyclic olefin copolymer (COC). Hochuen’s design engineers were able to create a high-precision, 4-cavity mold and carried out all the strict validation. They are currently the sole supplier of manufacturing for this critical component, which they are making over 200,000 units annually and enabling their customer to mass produce and get their diagnostic system on the market.
