Ceramics

We specialize in molding advanced ceramic materials, including Zirconia and Alumina, and customizing parts to precise client specifications. We employ a dependable approach to ceramic injection molding based on our long-standing practice and technical expertise. Our ceramic components offer a high level of toughness, reliability, and resistance to extreme conditions, which enables their application in challenging environments.

Alumina

Alumina is one of the most widely adopted ceramic materials. It is composed of Aluminum Oxide (Al2O3), which is the chemical compound of aluminum and oxygen. It offers electrical insulation, high temperature and chemical resistance, thermal conductivity and also provides superior abrasion resistance.

Purity levels for alumina range from 85% to 99.9%, supporting temperature ranges of: 100°C to 1600°C.

Applications include:

  • Semiconductor components
  • Mechanical and pump seals
  • Electrical insulators (i.e. spark plugs)
  • Electrical terminal strips
  • Flow regulators
  • Catalyst supports
  • Wear and heat resistant liners
  • Water filtration and purification
  • Armor protection
  • Lithium-ion batteries
  • Bearings
  • Glass
  • And many other applications

Zirconia

Zirconia, also known as Zirconium dioxide (ZrO2), is black or white in color. It is one of the most widely researched ceramics. It is chemically unreactive, has high temperature, mechanical, and abrasion resistance and is often used for appearance parts.

Applications include:

  • Fluid handling
  • Medical components
  • Aerospace
  • Cutting tools
  • Electronics
  • Fluid metering
  • Biomedical
  • Micro Engineering
  • Fiber optics
  • Nozzles for Extrusion and Spraying
  • Parts used in machines that use vision systems
  • Parts where the color and finish of the material is needed for aesthetic reasons
  • Areas that require higher strength coupled with a higher wear resistance

Plastics

Wunder-Mold has been injection molding plastics for over twenty five years. During that time, we have gained a great deal of experience in a wide variety of plastic types, a few of which are mentioned here. From soft rubber to glass-filled plastic, if you have a requirement for plastic parts, Wunder-Mold provides the experience molding a wide range of materials and sizes utilizing single and multi-cavity injection molds.

Polycarbonate (Plain or Filled)

Polycarbonates are a group of thermoplastic polymers containing carbonate groups in their chemical structures. Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent. They are easily worked, molded, and thermoformed.

ABS

Acrylonitrile butadiene styrene is a common thermoplastic polymer. Its glass transition temperature is approximately 105°C. ABS is amorphous and therefore has no true melting point. ABS is terpolymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene.

Polyolefins

A polyolefin is a type of polymer produced from a simple olefin as a monomer. For example, polyethylene is the polyolefin produced by polymerizing the olefin ethylene. Polypropylene is another common polyolefin which is made from the olefin propylene.

Nylons

Nylon is a generic designation for a family of synthetic polymers, based on aliphatic or semi-aromatic polyamides. Nylon is a thermoplastic silky material that can be melted processed into fibers, films, or shapes. It is made of repeating units linked by amide links similar to the peptide bonds in proteins.

Rubber

Natural rubber, also called by other names of India rubber, latex, Amazonian rubber, caucho or caoutchouc, as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds, plus water.

Acrylics

Poly(methyl methacrylate), also known as acrylic, or acrylic glass, as well as by the trade names Crylux, Plexiglas, Acrylite, Lucite, Perclax, and Perspex, among several others, is a transparent thermoplastic often used in sheet form as a lightweight or shatter resistant alternative to glass.

Polyacetal

Polyoxymethylene, also known as acetal, polyacetal, and polyformaldehyde, is an engineering thermoplastic used in precision parts requiring high stiffness, low friction, and excellent dimensional stability.
