When you need a thin-wall, durable, hollow plastic product or component for medical or food-safe applications, polymer blow molding is the ideal process. At Aptyx, we have the experience to bring your product ideas to reality, whether you’re using one of our existing molds or need a new custom mold. We also offer a full suite of complementary processes such as in-mold decoration. Our skilled craftspeople have extensive custom blow molding expertise with medical balloons in a wide range of profiles.
Advanced blow molding technology,
customized for you.
Expertise in medical balloons and other precision components
Blow molding solutions you can count on.
Aptyx provides versatile blow molding services for the medical device industry and other high-performance markets. Whether you need high-volume 4+4 continuous extrusion blow molding or micro medical blow molding for complex components like medical balloons and cuffs, we have the capabilities to bring your product ideas to reality.
Combining control and cost-effectiveness.
Polymer blow molding allows you to produce a hollow complex part design at scale. This process uses compressed air to meld down a specialized polymer tube (called a parison) to create a uniform shape and thickness around the walls of a metal mold. The OD can be controlled via a steel or aluminum mold and the ID via compressed air.
Blow Molded Products
Medical balloons & cuffs
We blow mold medical balloons and cuffs for a wide range of applications including endotracheal, stent delivery, tracheostomy, endoscopy, gynecology, and urology applications. Our team has decades of experience producing thin-walled cuffs that are durable yet supple with a limited transition from the balloon shoulder to the tube. We can provide you with blow-molded components with walls as thin as .0015” and with shoulder IDs as small as .075”.
Food safety applications
We manufacture blow-molded handles for the food and beverage industry that meet stringent quality and industrial safety standards.
Polymer Blow Molding Advantages
Efficient high-volume production
Once the mold or die has been fabricated, the blow molding process can quickly and reliably produce parts, making it a good choice for medium and high-volume production of the same hollow part.
Control of wall thickness & complex designs
Compared with dip molding, blow molding allows for improved control of wall thickness, along with more advanced, complex mold designs.
Cost-effective production process
Extrusion blow molding uses a lower level of pressure, which reduces machinery costs. This makes it easier and more cost-efficient to mold external threads or open-ended and large parts, which can be split by opening a closed molding. This technology also reduces labor cost.
