Plastic processing applications

Plastic injection molding is a popular manufacturing process used to produce a wide range of plastic products. This process consists of passing plastic material through a heating and mixing process and injecting it into a mold.

Solid State Relays in plastic processing equipment

Our new generation of Solid State Relays improve quality and speed of plastic processing equipment !

Production equipment must be quick and long-lasting.

Celduc offers SSRs for each application in the plastics industry :

  1. Extrusion
  2. Plastic injection molding
  3. Blow molding
  4. Thermoforming
  5. Recycling
  6. 3D printing

High reliability and long electrical life

Solid State Relays are ideal for use in plastic injection molding machines. They are preferred over electromechanical relays because of their extended lifetime, resistance to shock and vibration, and fast switching.

SSRs can be used to switch the barrel and mold heaters, allowing for precise temperature control, thanks to the SSRs ability to switch fast and often.

Celduc’s SSRs are known for their high reliability and long electrical life, making them ideal as heating element control in extrusion and injection equipment for plastics. Limiting machine breakdowns and maintenance offers long term savings in cost of ownership : once installed, the devices remain operational almost indefinitely.

Compact design and Rail Mount options

The compact design and Rail Mount options also help save cabinet space and extends reliability.

Ready-to-use design

The ready-to-use design, due to the optimally adapted heat sink, allows a quick and easy commissioning in just a few steps. In fact these products offer defined rated currents to make selection as easy as possible. 

Why use Solid State Relays in your equipment ?

  • Long lifespan
  • Very low energy consumption
  • Silent operation
  • Resistant to Shock and Vibration
  • Very precise temperature control thanks to high frequency switching
  • Accurate switching time
  • Additional functionality is possible: diagnostics, protection & communications can also be integrated into our products

Magnetic proximity sensors in plastic processing equipment

celduc® relais also supplies magnetic proximity sensors to manufacturers of plastic processing equipment.

Safety magnetic proximity sensors ensure operator safety and maximize the operating reliability of your equipment (example : celduc’s Safety Sensors are used to ensure that the cover is down when the 3D-printer is operating).

Why use Magnetic Proximity Sensors in your equipment ?

  • No power supply necessary
  • Large activation range
  • Operate in harsh environments (humidity, dust)

Innovation & trends in the plastics industry

Innovation can occur in the production, processing and recycling of plastics

The plastics industry is one of the most rapidly growing industries in the world. This is largely due to advances in technology that have allowed firms to create products that are both more durable and lighter in weight.  However, with this growth comes an increased demand for environmentally friendly materials, which has led to developments in the plastic manufacturing sector.

While plastic has many benefits, including its durability and low cost, it also presents a significant environmental challenge. Plastic waste is a major contributor to pollution and poses a threat to wildlife and ecosystems. And therefore, there is an urgent need for innovation in plastics manufacturing to create more sustainable and eco-friendly solutions.

New production methods

There are a number of innovative production methods that are changing the way plastics are made :

3D Printing / Additive Manufacturing

3D printing is a process where a three-dimensional object is created by adding layers of material on top of each other. In the case of plastics, a 3D printer uses a special plastic filament to build up the object layer by layer. This technology is revolutionizing many industries, including plastics manufacturing, by allowing for the creation of complex shapes and designs that would be difficult or impossible to produce with traditional methods. Moreover, it is also more efficient in terms of material usage as it only uses the exact amount of plastic needed to create the product, reducing waste and minimizing the impact on the environment.

Celduc’s SSRs are used in industrial 3D printers. For more information, you can read our latest Blog article.

Sustainable Practices in Plastic Manufacturing

Overall, sustainable manufacturing processes are an important innovation in the plastics industry, helping to promote environmental and social sustainability. It involves the use of environmentally friendly practices in the production of plastic products. This includes the use of sustainable materials, energy-efficient production processes, waste reduction strategies, and eco-friendly additives.

Celduc can support Plastics equipment manufacturers in their new development to optimize production processes to reduce energy consumption.

Recycling Machines

The recycling process for plastics involves several steps, including sorting, cleaning, shredding, and melting the plastic. The plastic is then formed into pellets, which can be used to create new products. The recycling process can be repeated multiple times, allowing the same plastic to be used and reused over and over again.

In recycling machines celduc’s SSRs are used for pre-heating and heating system control as well as for granulate sanitisation system control.

A Solid State Relay is the solution when the system designer needs to switch loads rapidly, as in all kinds of temperature control applications. Solid State Relays are used extensively in the Plastics &  Packaging processing industries and are an excellent replacement for electromechanical relays.
