Plastic Products Manufacturing Company
Medical Injection Molding
Medical and pharmaceutical products play a vital role in the health and safety of patients. As such, ensuring the quality of each product and its individual components throughout the manufacturing process—from design to final inspection—is essential. For this reason, it is vital to partner with an experienced medical/pharmaceutical component manufacturer that emphasizes quality and offers complete part traceability from start to finish.
The Importance of Plastic Injection Molding in the Medical & Pharmaceutical Industries
Plastic injection molding is an efficient and cost-effective method of producing medical and pharmaceutical parts to high levels of precision, accuracy, and quality. It is used to create components from medical devices and equipment to laboratory tools and testing instruments. The following page provides an overview of the plastic injection molding process and its essential role in the medical and pharmaceutical industries.
Advancements in material manufacturing techniques and technologies have led to the widespread use of plastics in modern manufacturing operations. In the medical and pharmaceutical industries, plastics are often used alongside the injection molding process to produce prototypes and full-production units of medical device and equipment components. As newer plastic materials and component designs are developed, injection molded plastics have increasingly contributed to lower infectious disease rates, better pain management, and lower medical costs.
At LHS Engineering Medical Molding, we specialize in full-service, turnkey plastic component injection molding solutions. Our comprehensive part manufacturing capabilities allow customers to maintain oversight over the production of their parts, resulting in greater transparency and accountability. Additionally, we maintain ISO certification and employ the use of FDA/medical-grade materials to ensure our injection molded components fully meet the strict specifications and standards of the medical and pharmaceutical industries.
Medical-Grade Plastic Options
The injection molding process accommodates a wide range of Plastic materials, making it well-suited to produce medical and pharmaceutical parts from whatever medical-grade plastic is required for the project. There are numerous plastics suitable for medical injection molding operations, each of which offers unique properties and performance characteristics. Common plastic material options for medical injection molding include:
- Polyethylene: Polyethylene is a widely used thermoplastics found in many industrial and commercial products. It is available in several variations—e.g., LDPE, HDPE, and UHMW—with varying levels of rigidity and durability. UHMW is often integrated into prosthetics for the hip, knee, or other joints.
- Polypropylene: Polypropylene is one of the most commonly used plastics. It is characterized by its ruggedness, durability, and elasticity, as well as its resistance to chemicals and electricity.
- Polystyrene: Polystyrene is a hard plastic with little to no flexibility. It exhibits excellent machinability, good impact resistance, and decent dimensional stability. It is often used for its aesthetic quality and easy-to-customize surface.
- Polycarbonate: Polycarbonate is a strong engineering-grade thermoplastic that offers dimensional stability and flame retardant properties. It is also resistant to damage stemming from impact, high heat, and UV radiation.
- PEEK: Polyetheretherketone (PEEK) is a high-performance thermoplastic known for its extraordinary mechanical properties, including resistance to thermal degradation, wear, tracking, and radiation.
