RION INDUSTRIES has extensive experience with special materials that can withstand exposure to chemicals, temperatures, variable stresses, and environmental conditions, while meeting all the international standards required for contact with drinking water if required.

In order to provide its customers with a high quality product that is optimally adapted to their requirements, RION specializes in the injection of reinforced materials and knows how to use them to pre-determine important parameters of the end product. For example, using nylon with fiberglass (PA+GF) strengthens the product and improves its mechanical characteristics.

 

The combination of RION INDUSTRIES vast expertise and experience with unique additives such as fire retardants and varying degrees of transparency, plus working closely with the best material consultants in the industry, as well as the ability to work with almost any existing material means that RION INDUSTRIES can provide each customer with an optimal solution.

RION-RAVEH, RION INDUSTRIES’ in-house mold manufacturer, designs and manufactures molds that are adapted to the characteristics of the injected material.

Ultem

Ultem is an amorphous material.

Characteristics:

  • High resistance to cutting and abrasion
  • Maintains its characteristics even during prolonged operation at high temperatures of up to 200°C
  • Contains structured fire retardants, built-in flame resistance
  • Maintains stable dimensions at high temperatures; Tg of ~217°C
  • In contrast to other amorphous materials, it is highly pressure- and crack-resistant
  • In contrast to other plastic materials, low toxicity during burning, similar to the level of burning wood

Applications:

  • Suitable for avionic parts and the military industry
  • PEI is very well suited for the medical industry in general and for the pharmaceutical industry in particular
  • The material is also suitable for the food and beverage industry, since it meets the standards required for potable water.

Challenges:

  • The main challenge is to design the product and the mold per the unique characteristics of the material
  • Although its melting temperature is relative high (between 350°C and 420°C), the material requires a relatively low mold temperature (between 100°C and 170°C only)
  • Major challenges in designing the mold: the material gates have to be large and production has to be without valve nozzles

Peek

PEEK is a semi-crystalline material.

 

Characteristics:

  • High resistance to friction and erosion
  • Maintains characteristics even during prolonged operation at high temperatures of up to 200°C
  • High rigidity
  • Stable at high temperatures; Tg of ~140°C
  • High resistance to chemical materials including bases, minerals and electrolytes
  • High levels of transparency

Applications:

  • Suited for use in aviation components due to its relative light weight yet high resistance
  • Suited for use in filtration systems and membranes, including bio-diesel systems, which are considered more destructive than other filtration systems
  • Very well suited for use in medical products and is one of the leading materials in medical implants, pumps and dialysis systems.
  • Also suited for use in the food and beverage industry, especially for high-temperature drying systems
  • Often used for hot water connectors due to its high temperature resistance

Challenges in the Injection Process:

  • The main challenge is working in a hot environment: Its relative high melting temperature (360-400°C) requires a high mold temperature (170-200°C). Thus both the product and the mold have to be designed accordingly.
  • Work at these temperatures requires molds of Class 101/102 according to the SPI standard.
  • Injection under these extreme conditions tends to introduce/apply stresses on the product (the material is sensitive to the process). These stresses create micro-cracks. In these cases the products must be tempered in a tempering furnace.

Reinforced Materials

RION uses diverse raw materials in order to meet customer requirements and specifications, including materials that incorporate additives – mainly in order to enhance the materials’ ability to meet stringent mechanical requirements. These requirements include withstanding variable work pressures (air/water shocks), vibrations, bending forces, shearing forces and more.

Fiberglass is the most common additive. This additive, along with injection directions, know-how and experience, result in exceptional performance of the final product.

Polysulfone

Characteristics:

  • High rigidity
  • Stable at high temperatures; Tg of ~150°C
  • Resistant to a broad range of chemicals such as bases, minerals, electrolytes
  • Resistant to oxidizing agents, surfactants, oils and hydrocarbons
  • High levels of transparency

Applications:

  • Widely used in membranes and filters because it is possible to precisely control the pore size down to very small dimensions. PSU membranes are used in hemodialysis, industrial wastewater, the food industry and gas separation. The polymer can be reinforced with fiberglass. Often used as an alternative to polycarbonate when stringent requirements have to be met.
  • PSU is often used in medical products that require autoclave or steam sterilization due to its ability to withstand high temperatures. (This polymer belongs to the family of thermoplastic materials with some of the highest temperature resistances in the industry.)
  • Used as an insulator (dielectric material) in the production of cables
  • Used for hot water connectors due to its excellent temperature resistance

Challenges in the Injection Process:

  • Its relatively high melting point (~360°C) requires a high mold temperature of 140°C -180°C (heaters for the mold, etc.)
  • Injection under marginal/extreme conditions tends to introduce stresses into the product (the material is sensitive to the process). These stresses create small cracks. In these cases the products must be tempered.

TPE/TPV

A family of co-polymers that have the characteristics of both thermoplastic and elastomer materials.

 

Characteristics:

  • Rubber-like materials that can be injected – as opposed to other rubber-like materials that have to be cured. The ability to inject lowers the relative cost of production.
  • Highly resistant to tearing and abrasion.
  • Heat- and oil-resistant
  • High resistance to bending and fatigue
  • Shear resistant
  • High resistance to knocks\
  • High resistance to chemicals, weather-proof
  • Maintains product dimensions over extended periods of time
  • They fall somewhere on the spectrum between hard materials, that are more similar to plastic, and soft materials, with a more rubber-like feel (from 20 Shore 00 up to 85 Shore D)
  • Most TPV/TPE materials can be recycled
  • Can be produced in a wide range of colors

Applications:

  • The materials are suitable for a broad range of fields: automotive industry, medical equipment, seals for a wide variety of uses, sports equipment, packaging, toys and more
  • TEP is very well-suited to the medical industry in general and to the pharmaceutical industry in particular
  • The material is also suitable for the food and beverage industry, since it meets the standards for potable water

Challenges in the Injection Process:

  • Requires highly precise control over the injection process
  • More likely to stick to the mold during the injection process
  • Difficulties in cutting off/trimming material inputs

PVDF

PVDF is a semi-crystalline material.

Characteristics:

  • Withstands high temperature
  • Abrasion resistant
  • Radiation resistant
  • Withstands most chemicals
  • Versatile, e.g., withstands stretching
  • Resistant to creep and fatigue

 

Applications:

Suitable for use with pipes and connectors.

Suitable for use as an insulator for cables.
