Production Equipment

Our team has the expertise to help you select the best size and type of equipment to optimize your project success. We also can help you validate your customized equipment, including installation qualification (IQ), operational qualification (OQ), and performance qualification (PQ). Production equipment options include:

  • High-Volume Chain Line
    High-volume continuous-chain dip coating systems, often referred to as drag chain lines, offer high-volume capacities for narrow product families with defined process parameters. These systems are capable of producing more than 1000 pieces per minute.
  • Batch
    Batch or robotic-style equipment offers the ability to repeatedly perform complex manipulations for large arrays of product sizes, geometries, and polymers. These systems allow you to vary process parameters through the control system to accommodate chemistry and product changes.

Test/Inspection Equipment

Thin-wall dip-molded products are often tested to detect functional imperfections in the film, called pinholes. For example, the FDA requires barrier integrity testing for medical exam gloves.

We offer testing equipment for all test methods, including:

  • Glove water leak test stands
  • Condom water leak test stands
  • Condom conductivity test systems
  • Glove inflation test systems
  • Bag inflation test systems

Spray Coating and Film Cast Equipment

Spray coating offers an alternative to dip coating for specific coating applications, products, and polymers. A variety of low-viscosity spray coatings can be applied in precision patterns to flat or multidimensional components. We’ve designed and supplied spray coating equipment for applications including medical devices, fuel cells, circuit boards, semiconductor wafers, solar photovoltaic products, and electronic display panels.

Our film cast equipment offers low- to medium-volume production rates for non-supported and supported films generated from liquid polymer solutions such as polyimide. Cast film equipment applications include wound care, drug delivery films, protective film, and electronics film production.

Our fully programmable control system allows for tracking and controlling subtle changes to key parameters. It also offers control and process monitoring as well as reliability for consistent performance.

Supporting coatings for a range of applications.

Identifying the optimal coating for performance needs.

We can leverage our coating expertise to help you to identify the optimal coating for your molded or extruded product. In the medical device industry, coatings are often offered as value-added options for existing products as well as requirements for new products to achieve certain performance characteristics. Other industries that benefit from coatings include industrial, electronics, building, automotive, and consumer products. Coatings are commonly used to achieve enhanced resistance to wear, static or electrical current, environmental hazards such as moisture or UV exposure, or to provide features that the base material doesn’t offer, such as surface tack or reflective properties.

Types of Coatings

We work with you to select and apply the coating most appropriate to enhance your product’s surface and performance characteristics.

Lubricious Coatings

Lubricious coatings reduce friction and facilitate insertion. Products to which lubricious coatings are commonly applied include:

  • Catheters
  • Cannulae
  • Guidewires
  • Sutures

Silicone Coatings

Silicone Coatings
Used to reduce friction, these coatings can be applied to individual products or in bulk.

Products commonly coated with silicone include:

  • Injection-molded products
  • Metal devices, instruments, and components such as syringe needles

Polymer Coatings

These coatings provide a protective layer to enhance wear of a molded product or to protect a product that is exposed to moisture. A wide range of products are coated with polymers including:

  • Scopes
  • Sheath covers
  • Surgical gloves

Drug-eluting Coatings

Medical devices can be coated to deliver drugs or hormones that are absorbed into the body. Products with drug-eluting coatings include:

  • Stents
  • Intrauterine devices (IUD)
  • Sutures

Antimicrobial Coatings

Medical products with an antimicrobial coating can help to reduce risk of infection or irritation to skin or a wound area. Products with antimicrobial coatings include:

  • Catheters
  • Sutures
  • Gloves

UV inhibitor coatings

These coatings are applied to materials such as glass and molded polymers that are subject to UV radiation; for example, coating glass vials that contain vaccines to increase shelf life when exposed to sunlight or fluorescent lighting.

Substrate Coatings

Fabric coatings

Coating a preformed shape, such as gloves, covers, and clothing, can provide a protective layer or a desired cosmetic appearance. Fabric coatings are also applied to enhance grip or provide hydration resistance for applications such as food or glass handling.

Metal coatings

Metal coatings often use polymers to help reduce friction, provide damping characteristics, or eliminate contact with sharp edges of stamped or formed metal products.

Paper & Cellulose Coatings

The food industry uses biodegradable coatings for food packaging. Coatings can also extend the life of utensils and food containers that come into contact with oils or waters.

What our customers are saying
They’ve been a good partner – good communication and meeting our needs…Open and honest. Good partnership.
Business Unit General Manager / Global Medical Device Company
One particular capability where they really stand above competitors is project management. This is done in a professional way, and we have quite high complexity involved. They are doing an outstanding job.
Global Commodity Manager / Multi-national Medical Device Company
The Aptyx team did an excellent job converting brass gears to plastic. Because of the design challenges, deep expertise in gears and over-molding was crucial. They also converted an expensive, labor-intensive part with quality issues to two-shot molding, which dramatically reduced cost, improved quality, and easily met the production needs. Apytx came through for us because of very good program management and good technical expertise.

Stents & balloons

Drug-eluting coatings for medical devices allow the slow release of a drug to prevent complications. For example, cardiovascular stents can be coated with a drug that helps prevent blood clots. Angioplasty balloons can be coated with a drug to reduce the risk of future blockage.

Silicone-coated injection-molded device

Silicone coatings are helpful in reducing friction in products such as autoinjector plungers or precision gears.
