Injection molding machines

Tailor-made solutions for non-standard requirements

Tailor-made solutions for non-standard requirements

Thick-walled moldings
Ettlinger injection molding machines are equipped as standard with a two-stage injection unit, which divides the "plasticization" and "injection molding" processes into two different sections. The resulting high plasticizing properties enable efficient processing of even demanding materials, such as recycled soft PVC.


Injection molding machine with integrated ERF filter
If recycled materials are treated by injection molding technology, they must be free of impurities in order to avoid disturbances in the treatment process, which can occur, for example, due to clogging of the nozzles of the hot distribution ducts. These impurities are usually separated by filtration from the melt in a separate regranulation process.


Large capacity marine applications
Ettlinger's injection technology is also used to manufacture oil and gas pipelines: welded steel pipes are reliably pressed to protect them from corrosion and mechanical influences. The special Ettlinger injection unit selected for the housing application has an extremely compact design and is optimally adapted to the limited space available on board. The entire electrical and hydraulic power supply components of this special injection unit are intricately encapsulated to prevent damage to the pipes by seawater and salty atmospheres.

Thick-walled moldings

Ettlinger injection molding machines are equipped as standard with a two-stage injection unit, which divides the "plasticization" and "injection molding" processes into two different sections. The resulting high plasticizing properties enable efficient processing of even demanding materials, such as recycled soft PVC.
For example, speed retarders and beacon bases have thick walls and solidification times during the manufacturing process are therefore very long. In order to be able to produce these products as economically as possible, Ettlinger injection molding machines have a rotary table with four stations. The machine can thus hold several injection molded parts at once until they are ready to be ejected from the mold. Long setting times are effectively compensated in this way because the output is higher.
Speed ​​retarders and beacon bases are often installed on the road to reduce speeds and protect road surfaces or increase safety. Soft PVC derived from recycled cables is usually used to make these products; due to its high density, it is relatively difficult, but at the same time very economical.

Injection molding machine with integrated ERF filter

If recycled materials are treated by injection molding technology, they must be free of impurities in order to avoid disturbances in the treatment process, which can occur, for example, due to clogging of the nozzles of the hot distribution ducts. These impurities are usually separated by filtration from the melt in a separate regranulation process.
With our injection molding machines, filtration and injection molding processes can be combined on one machine. To this end, our ERF continuous melt filter is integrated between the plasticizing and injection unit, which cleans the contaminated melt in a single process step. Therefore, another regranulation line with melt filtration is no longer necessary. As a result, material processing is much more environmentally friendly and much more energy efficient, and system investment and space requirements are significantly reduced.
 

Large capacity marine applications

Ettlinger's injection technology is also used to manufacture oil and gas pipelines: welded steel pipes are reliably pressed to protect them from corrosion and mechanical influences. The special Ettlinger injection unit selected for the housing application has an extremely compact design and is optimally adapted to the limited space available on board. The entire electrical and hydraulic power supply components of this special injection unit are intricately encapsulated to prevent damage to the pipes by seawater and salty atmospheres.
In addition, because a large amount of material is required to completely remelt the weld with respect to the pipe diameters used (up to 1000 mm), the unit has a maximum injection volume of 140,000 cm3.
Oil and gas pipelines are being built at sea on so-called carrier vessels. The individual steel pipe sections are mounted together here and therefore have no protective or insulating layer at the ends. After welding the pipes and immediately before lowering them into the sea, the welding zone is coated with a plastic sheath to protect it from damage by seawater.
