Features of Medical Device Injection Mold

——

1) Widely applicable medical device injection molds KRMOLD medical device plastic injection molds can be used across various medical applications to manufacture common medical devices such as syringes, inhalers, medical trays, catheters, surgical tools, and components for blood glucose meters and blood pressure monitors. Single-use or reusable elements in the medical field can be plastic parts made with KRMOLD medical device plastic injection molds.   2) High-precision medical device injection molds To guarantee net-shape components made by KRMOLD engineers achieve exceedingly repeatable tolerances as low as +/- 0.001 inches or less using precision-machined steel molds. KRMOLD medical device injection molds hardly call for any additional processing. This makes it possible to preserve difficult geometries at high production levels within narrow tolerances.   3) High-volume medical device plastic injection molds KRMOLD medical device injection molds can produce thousands of parts per hour. Increased automation reduces labor costs, while low mold scrap rates and minimal secondary operations improve cost efficiency. The purchase cost is quickly recovered.

4) Customized medical device injection molds Based on the use case and particular customer needs, KRMOLD may create unique medical device plastic injection mold manufacturing solutions. With wall thicknesses between 0.5 mm and 6 mm, KRMOLD medical device injection molds may create plastic pieces weighing anything from a few grams to several pounds. For smaller medical device components, KRMOLD engineers utilize micro injection molding technology.   5) Repeatable medical device plastic injection molds KRMOLD medical device plastic injection molds implement strict process control, automatically monitoring process parameters such as temperature, pressure, and cycle time to ensure that every part meets specifications. KRMOLD offers inspection methods that allow easy visual or automated detection of part defects, ensuring product quality.   6) Standard-compliant medical device plastic injection molds KRMOLD guarantees that medical device plastic injection molds generated meet regulatory standards of the customer's area by using medical device standards. demands in areas including the US FDA, the European CE Mark, and the Japanese PAL. In terms of materials, manufacturing methods, sterilizing techniques, and bio-compatibility testing, KRMOLD medical device injection molds adhere to medical device requirements and quality standards.

Common Plastic Injection Molding Techniques for Medical Device Injection Mold

——

1) Gas-assisted injection molding

Gas-assisted injection molding solves the problems with unequal drying or curing of thicker components seen in typical molding. Nitrogen is flowed through channels made into the medical device injection mold, therefore giving the resin the necessary pressure to produce smooth, structurally sound components.

2) Insert molding

Usually used to make a tight, leak-proof joint, insert molding lets a second piece be cast on top of a pre-molded one. Putting an already present component into a medical device injection mold and then injecting melted plastic creates a robust molecular or mechanical connection. This technique is widely used in the production of various medical devices.

3) Overmolding

Overmolding coats a polymer onto a substrate to create a single, integrated component, hence doing away with the requirement of assembly. This technique is perfect for high-volume manufacturing and is sometimes used to produce ergonomic surgical instrument handles.

4) Liquid silicone rubber injection molding

Liquid silicone rubber injection molding is suitable for the production of medical devices with high hygiene requirements, such as tubing and respiratory masks. This technique promises a dust-free and moisture-free production environment and produces a chemically resistant, rubber-like substance appropriate for safe implantation.
