With the rapid advancements in healthcare, plastic has emerged as the favored material for prototyping crucial medical components:

PTI’s injection molding equipment investment includes (48) horizontal and (5) vertical presses ranging from 35 tons to 300 tons. Many are automated and use robotic systems to maximize efficiencies and ensure quality. At PTI we take the partnership approach on every project, bringing to the table more than 35 years of plastic injection molding knowledge and technical expertise in a facility designed to deliver an all-inclusive plastic injection molding experience.

PE consists of ethylene monomer units linked through addition polymerization. Its variants offer distinct mechanical properties suited for various applications:

The mechanical and chemical attributes of plastics significantly influence the durability and functionality of medical devices. Some important mechanical properties include:

Medical-grade plastics like polyethylene, polypropylene, PVC, polystyrene, and silicone offer exceptional durability and biocompatibility. Understanding these properties and the material standards for each ensures you produce durable, reliable devices.

Join us as we explore different types of medical-grade plastics and the critical factors in injection molding material selection.

Medical device aesthetics and usability contribute significantly to patient experience and acceptance. Visible prosthetics benefit from appealing, durable molding materials like colorable polycarbonate.

Plastic medical products have revolutionized and improved the quality of patient management globally, but not all materials are created equal. Choosing suitable plastic materials for your medical device manufacturing is essential, as it impacts the success and safety of your final product.

PTI’s custom plastic injection molding services span from a single prototype injection molding to full production quantities. Regardless of job type—prototype, short-run, low-volume, or multiple-cavity—you can be assured all aspects of plastic injection mold construction are monitored and controlled. This attention to production detail ensures the goals, objectives, and predetermined project outcomes are on schedule throughout each phase of the process. All services, from design through manufacturing, are completed in house and contribute to providing our customers with competitive advantages in cost, quality, and lead times.

Selecting the right materials for your medical devices is critical for determining the final product’s performance, safety, and efficacy. Here are a few key factors guiding the intricate injection molding material selection process.

Usability involves factors like handling ease and comfort. Silicone, prized for flexibility and skin comfort, is common in wearable medical devices. Plastic mold technology provides the design flexibility to create intricate and ergonomic designs, enhancing the overall usability of medical devices.

PCTFE is derived from replacing all remaining hydrogen atoms on the monomers with fluorine. The resulting material is ideal for pharmaceutical packaging thanks to its excellent strength, impact resistance, and moisture resistance.

PVC is derived from substituting a hydrogen atom with chlorine in the ethylene monomers, which reduces its reactivity to nonpolar liquids. It is also transparent and flexible, making it a strong choice for storing glucose and saline solutions.

Sterilization compatibility is also crucial to maintaining the hygiene and safety of medical devices. Injection molded parts must have high heat resistance to withstand various sterilization methods such as autoclaving, gamma radiation, or harsh chemical agents.

Plastics, also known as polymers, consist of repeating monomers forming homopolymers or copolymers. These materials are arranged into linear or branched polymers, resulting in diverse plastics with unique features.

Thermoplastics can be hard yet highly flexible. They can resist bending but offer excellent tensile strength that protects them from breaking.

As your partner, Crescent Industries can provide expertise in injection molding manufacturing and uphold ISO standards, ensuring high-quality medical plastic products. Contact us for unparalleled quality, speed, and value in medical injection molding.

Thermoplastics also feature weaker intermolecular forces, allowing them to melt and reform multiple times without permanent alteration. The material’s versatility and ability to withstand the remolding processes make it ideal for medical device plastic injection molding.

Biocompatibility involves assessing how materials interact with living tissues. Medical devices often come into direct and prolonged contact with bodily fluids or tissues, making biocompatibility a top priority.

Polypropylene is derived from substituting the ethylene monomer with a methyl group (CH3). It is harder than PE and offers better resistance to moisture and gases, so it's suitable for storing fluid drugs. PP is also autoclavable and chemically robust, expanding its utility for storing sterile drug products.

Medical injection molding utilizes various types of plastic materials. Thermoplastics and thermosetting materials are prominent in this field. Thermosetting plastics have high melting points, chemical resistance, and mechanical strength due to the strong covalent bonds between polymer strands. However, these covalent linkages cannot reform once broken, resulting in permanent deformation. These properties make thermosetting plastics useful as adhesives and protective coatings.

Chemical resistance is crucial for devices exposed to cleaning agents and bodily fluids, ensuring longevity and reliability. Understanding and utilizing these properties to their best advantage is essential for maximizing device performance in medical applications.

Our process engineers and technicians adhere to the International Standard of Mold Making, SPE, and SPI guidelines. We are ISO9001:2015 registered and practice scientific molding with certified capabilities to use RJG or equivalent technologies. All standards are correlated throughout our manufacturing and quality systems at PTI.

Industry standards are essential guidelines that ensure end-users are safeguarded from undue risks associated with medical molded products. Regulatory bodies like the EU MDR (Medical Device Regulation) and the U.S. FDA (Food and Drug Administration) categorize medical devices into three classes, each correlating with a distinct level of risk. They include:

PEEK is celebrated for its unique biomimetic qualities and fatigue resistance. It's commonly used for orthopedic implants and prosthetics.

To adhere to these tight tolerances and standards, injection molders must implement rigorous procedures at every production stage. Some of these standards include:
