We are a Medical mold manufacturing supplier with formal qualifications. Our medical products include but not limited to injection molding, mold pressing, extrusion, etc. We are high precision mold manufacturing, efficient production equipment, and high demand for product quality centered, producing all kinds of medical and person care products.
The manufacturing and production of medical product molds also reflect a company’s manufacturing level and strength. Completing a good set of medical molds requires excellent designers, high-precision processing machines, and a production environment that meets the requirements. These are the basic requirements of medical products. GREFEE’s dust-free workshop is built strictly according to photo requirements, reaching a cleanliness level of 100000, which meets the production requirements of medical products.
Medical products production must strictly follow ISO medical devices quality management system, including material purchasing, production control, product inspection and the requirements of all sections to ensure the product safety, stability, reliability. In addition to the regulation of workshop, our staff also strictly follow the requirements of 100000 level workshop.
GREFEE provides mold manufacturing and production services for global medical companies. Our services include constructive design solutions, precision manufacturing solutions, efficient production solutions, and packaging design solutions. In addition to conventional injection molding production, we also support silicone product molding production processes, regulated silicone extrusion production processes, and silicone tube foaming production processes.
extrusion medical silicone product:
Extrusion silicone products are suitable for products with regular shapes and large output. The advantage of extrusion can be continuous, and long term production. At the same time, it is also a kind of processing ith less waste, which guarantees the raw material can be fully utilized during the extrusion process. Below are some common types of GREFEE extrusion silicone products.
Medical silicone catheter: This catheter is made of high-quality imported silicone as raw material, which is non-toxic, odorless, non-irritating, non-allergic, and has good biocompatibility. It also has high temperature and low temperature resistance, and can be used normally at -60 ℃ -250 ℃. The product hardness can be selected from 30A-80A, and it can be directly used through ethylene oxide sterilization packaging. The main application areas include the medical device industry, beauty equipment industry, medical equipment accessories, and pharmaceutical equipment accessories.
Product features:
Biocompatibility: Medical silicone tubes have excellent biocompatibility and are compatible with human tissues and body fluids, reducing irritation and allergic reactions to the human body.
Softness and elasticity: Medical silicone tubes have good softness and elasticity and can adapt to different curves and shapes.
Antibacterial property: The surface of medical silicone tubes usually has antibacterial properties, which can effectively inhibit the growth of bacteria and microorganisms.
Chemical resistance: Medical silicone tubes have excellent chemical resistance and can withstand many common chemicals.
Wear resistance and oxidation resistance: Medical silicone tubes have high wear resistance and oxidation resistance, and can be used for a long time without aging and breakage.
Provide ISO 10993 testing, including biocompatibility testing.
In addition to scientific testing, we conduct routine and rapid tests on each batch of products to verify whether the product materials meet the requirements of medical products through the simplest tests. The rapid tests include: twisting, pulling, winding, tearing, flame retardancy and other aspects.
By twisting, pulling, and wrapping to observe whether the silicone product content will turn white, deform, size, and transparency.
Tear to verify the tear elongation of the product, so as to determine the size change of the product when it is damaged.
By high-temperature combustion, observe the flame, dust, and odor to determine whether the material meets the material parameters.

Similar products of the same type using extrusion technology 2: Silicone cross drainage tube.
Similar products of the same type using extrusion technology 3: Double-lumen urinary catheter
Similar products of the same type using extrusion technology 4: Triple-lumen urinary catheter
All processes are completed in a 100,000-class cleanroom. From production, post-processing to packaging, everything is in accordance with medical product standards. All products are sterilized with ethylene oxide before packaging, ensuring safety.
Liquid medical silicone products:
The most commonly used process is the compression molding process or the production of special-shaped silicone products. The compression mold is composed of two mold cores and a mold core, and has a simple structure. The advantages of the compression molding process are mainly reflected in the good structural strength, excellent surface quality and high production efficiency of the products produced. At the same time, the mold manufacturing of the compression molding process is relatively simple, the manufacturing and production cycle is short, the mold life and the mold process flexibility and adaptability have good performance, therefore, the compression molding process is very suitable for large-scale production.
Liquid silicone process:
The production process of liquid silicone process is a complex and precise project. Not only requires equipment with high precision and product environment, but also relies on accumulated experience. Liquid silicone products solidify process is essential, which needs to be completed in a high temperature and high pressure environment through vulcanization equipment.
Liquid silicone product features:
High elasticity: Liquid silicone products have very high elasticity, can withstand large deformation, can effectively solve vibration and impact, and reduce the risk of product damage.
Flame retardant performance: Liquid silicone products can reach UL94 V-0 flame retardant level, silicone materials produce less smoke when burning, and do not contain toxic substances.
Chemical resistance: Liquid silicone products have strong tolerance to some chemical properties such as acid resistance/alkali resistance/solvent resistance/oxidation resistance.
Chemical resistance: Liquid silicone products have strong tolerance to some chemical properties such as acid resistance/alkali resistance/solvent resistance/oxidation resistance.
Low and high temperature resistance: Liquid silicone products can fully maintain good performance at extreme temperatures, and can withstand temperatures between -60℃ and 250℃. This makes it suitable for applications that need to work under various environmental conditions.
Good sealing performance: Liquid silicone products have good sealing performance, which can effectively prevent the penetration of water, gas, dust and other substances, and protect the interior of equipment and buildings from the influence of the external environment.
Silicone product production equipment: Customized service is adopted to customize mold fixtures according to product specifications. It is suitable for most molds, can realize the fully automated production of molding molds, and reduce production costs.
Silicone mold warehouse: molds are placed separately according to their specifications. We also provide 3 years of free mold storage service and regularly maintain the molds to ensure mold quality.
Assembly workshop: We have rich assembly experience and assembly equipment, which are suitable for most medical product assembly, such as balloon bonding, catheter drilling, etc.
Testing Center: All products are 100% fully tested to ensure that all products meet medical requirements.
Packaging workshop: It meets the requirements of 100,000-level clean workshop, and all products are sterilized with ethylene oxide before packaging.
