Medical Plastic Material

Medical Plastic Material

The use of plastic materials in the medical field is constantly increasing and is estimated to reach 4 billion dollar in two years (only in the US).
The need to reduce healthcare cost and use of a disposable medical supplies are important factors generating a higher demand of medical plastics.
New materials, with improved properties are developed in order to satisfy the requirements of infection control standards.
New studies and tests are conducted to determine the biological reactivity of polymeric materials.
Currently, plastics are graded on a scale of Class I to Class VI, which is done by injecting extracts of the test material intracutaneously into rabbits and mice.
Plastics not requiring implantation testing are graded Class I, II, III, or V and those plastics requiring implantation testing are graded Class IV or VI.
Guidance for the use of plastics in the manufacture of medical devices not being provided in the past, the medical device industry has primarily used Class VI plastics. The overuse of Class VI plastics is due to the assumption that its advanced level of testing the legal and biological risks are reduced. This leads to manufacturers avoiding the use of a number of appropriate and preferable plastics or polymers.
Packaging of medical plastic parts, tubes and pharmaceutical closures are also applications for plastic materials.
The high impact and chemical resistance as well as excellent resistance to steam exposure of some materials (like polyphenylsulfone) is making them a strong choice for products that need to be sterilized.

Injection Molded Products

Injection Molded Products

Quashnick Tool works closely with customers to develop products which can be molded accurately and economically. Employing SPC, Six Sigma and working toward ISO certification, we supply our customers with injection molded parts that consistently exceed their dimensional, aesthetic and performance requirements. Our staff strives to meet our customers scheduling and production needs and we stand behind our products 100%. Please review the following molded part categories for more information and contact us if we can assist you with your next project.

With our fully equipped Production Plastic Molding department we are able to sample and troubleshoot problem molds, run hand-load and overmolded parts as well as multi-cavity, high production molds. As a custom molding facility we have experience working with a large variety of polymers ranging from standard commodity resins like Polypropylene to more challenging grades of engineering resins such as PEEK and LCP. Over the past 35 years, Quashnick Tool Corporation has been involved in hundreds of projects relating to each of the following fields:

  • Medical Disposables
  • Medical Devices
  • Automotive
  • Consumer Products
  • Electronics
  • Computer & Peripheral Devices
  • Connectors
  • Telecommunications
  • Space & Military
  • In-Mold Decorating
  • Micro Molding

Our emphasis, as directed by Mr. Quashnick himself, has always been quality and accuracy. This is reflected in both the Injection Molds we manufacture as well as the Molded Plastic Parts they produce.

Plastic Injection Molding for the Medical, Biotech and Hightech industries.

For 39 years Quashnick Tool Corporation has developed custom injection molding for the who’s who of technology companies in the greater San Francisco Bay Area.
Knowing what’s at stake when it comes to developing and maintaining quality plastic injection molds and the parts produced is the secret to their continued success. They realize that when companies begin new designs of molded materials, significant corporate R&D, engineering, manufacturing, administrative and support resources are at stake. Any redundant or rework efforts will add cost, delay time –to- market, and may upset medical device trials and qualification.


With this reality in mind they work with you to look as far ahead as possible in foreseeing and side-lining potential pitfalls in a successful molding program. Quality Pros think of it as it “FEMA” in action. They do this specifically by drawing from their 39 years of experience, merging extensive design and materials experience, with state of the art corporate management and sophisticated engineering and project management skills.
Whether you are looking to work with extremely tight time lines, wish to minimize development risks, want to keep manufacturing local in the greater Bay Area, or you are looking to save costs by building tools at a qualified QTC offshore partner, it pays to have a well versed and professional organization shepherd you through the process.
They’ve delivered success for several hundred companies in the greater Bay Area since 1971. They will deliver success for you.

Quashnick Tool Corporation was founded by State Certified Journeyman Tool Maker and past President, Terry Quashnick and his wife Jeanette in 1973. For the first eleven years they specialized in the design and construction of injection molds. In 1984 they added injection molding to the business.

Inducted into the Society of Plastic Engineers Hall of Fame in 1998.

In 2008, Terry assumed the role of CEO/CTO to focus on technical development when Ed Baker joined the firm as President and COO.

After 37 years of operation, QTC remains a custom manufacturer with two divisions and has built a team of versatile and experienced employees to meet any customer’s injection molding needs.

The tooling division specializes in the construction of complex plastic molds built to very high tolerances.  Technology is an important component at QTC and the company continues to invest in the latest machinery and metrology equipment to maintain our reputation for competitiveness and quality.  Also incorporated in the tooling division is one of the most advanced computer aided mold design facilities in Northern California, which utilizes the latest versions of Pro/Engineer, AutoCAD, SolidWorks and SURFCAM.

As the industry has changed, QTC has changed with it, with a focus on clean manufacturing and producing higher volumes of complex medical parts, in addition to custom work. The molding facility currently operates eleven state of the art injection molding presses ranging from 35 to 230 tons across the entire spectrum of resins from polypropylene to engineering resins.

Today, QTC operates using lean business processes, ISO level documentation, six sigma problem solving tools and a total team concept, to seamlessly integrate mold design, mold construction and plastic molding operations, and assure we deliver quality parts to our worldwide customer base.
