New pultrusion plant opening in Latvia

11. March 2019


Tinby is the pleased to announce the opening of their new 1,100 sq.m. plant in Latvia - where we will focus on the manufacture and distribution of pultruded products to our customers. 

With a manufacturing hall of just over 1,100 sq.m., Tinby will be well-equipped to begin manufacturing composite profiles using pultrusion at our new facilities in Latvia - under the name Tinby SIA. 

What is pultrusion?

Pultrusion is a process whereby continuous reinforcement material is pulled through a tool in which the fibres are placed precisely in relation to the profile cross-section – or according to any specifications the client may have provided in relation to the particular product. The fibres are then led through the next tool, where they are impregnated with a matrix material, after which the profile is cured in its final geometry. The fully-cured profile is then pulled forward to a saw which cuts the profile into defined lengths. The process makes it possible to optimize both the properties of the material and the shaping of the individual article.  

Simply put, pultrusion is the shaping of a woven thread of fibre into the geometry and strengths that you need. The method ensures a consistent quality that can be reproduced as required.


Versatility is the key in our production halls

In addition to constantly developing pultrusion technology, Tinby also actively develops new products in collaboration with our clients. Therefore, we will be working closely with our clients at our Latvian plant to produce any type of profile they could possibly need, where a high degree of strength is required. This is particularly relevant in the wind energy sector which requires materials with long lifespans, and that are extremely strong, heard-wearing and resistant to the weather conditions. Tinby's construction profiles fit the bill here, and live up to the stringent requirements that apply, making them the obvious choice for wind turbine elements for clients all over the world.  

What are the advantages of using pultrusion?

As the final protruded product is made of a composite material, i.e. a combination of different materials, one of the primary and most important advantages is that the items produced are much stiffer and stronger in relation to their density - compared to a large number of other materials. In many cases, plastic composites can thus replace materials such as steel, where, as we all know, continuous maintenance is a necessary evil. In comparison, composite items require only minimal maintenance. Other significant advantages offered by pultruded products are that the composites can be moulded or shaped into lightweight components that have a complex geometry, are lightweight and highly flexible. 

Due to the minimal maintenance involved, their high durability and longer lifetime, there are a lot of savings to be made when using Tinby's composite solutions. In principle, pultrusion works in the same way as our polyurethanes (PUR); by combining the various types of fibres with a matrix mixture, we can design the finished material in the exact strengths and degrees of stiffness the client desires, regardless of whether the items are to be used in the transportation, automotive, wind, building, sanitation or marine industries. Or for something else altogether.
