Established in 2016, Welement Factory is brand new and it is unlike any factory you'd expect to see in a Baltic Country.
This strikes you as soon as you get to its entrance.

On the factory floor, Welement sports cutting-edge technology in a quasi-sterile environment... but on the outside, it looks like a beautiful modern home.

The entrance to Welement Headquarters is indeed the best setting we've seen so far in a house factory.
The vertical larch cladding is a perfect example of what this Company is set to accomplish: creating beautiful wooden buildings.

Stepping inside keeps up with the expectations.

The reception desk and the furniture in the main corridor are made out of massive timber.
This space feels warm and well designed. Although minimalistic, it screams quality and attention to details.

The way Welement presents itself is nothing short of spectacular. factory review welement entrance

Welement does not offer services of architectural design and it requires its Clients to present their own architectural plans.

Engineering design is developed using HSBcad, an AutoCAD based software with 3D capabilities.

Once ready, the design can be digitally transferred to the machines on the factory floor that will take care of cutting the necessary timber parts to measure. 

6.3. Production Process

Welement production is one of the most advanced in Estonia.
It relies heavily on machines and automation and there are 18-20 workers on the factory floor.

The Factory Manager supervises the production process from his office located directly on the factory floor. factory review welement production office

In-factory Office.

6.3.1. Material Supply

Materials used in production are sourced locally by distributors operating in Estonia (Welement does not import materials on its own).
All material used in production are CE marked, with exception of cross-laminated timber which is purchased mainly from Latvia.

Among the major suppliers of wood: Stora Enso, Raitwood, Puidukoda, Pinska, Palmako, Peetri Puit.

Wooden windows used in production come mainly from Viking or Nordan.

6.3.2. Painting

Welement does not paint parts inside its factory.
Painting of all the colored parts is performed by a third party at the moment of sourcing of the materials (primer + first hand of paint).

A final layer is applied by Welement in the factory once the element is fully assembled.

Welement bears full responsibility for the quality of the painted surfaces and their conformity to the requirements set by the Customer.

Available painting solutions:

  • stain
  • water paint
  • oil paint

6.3.3. Impregnation

Welement does not impregnate parts inside its factory.
Impregnation of all the impregnated parts is performed by a third party at the moment of sourcing of the materials.
Welement bear full responsibility for the quality of the impregnated parts and their conformity to the requirements set by the Customer.

Available impregnation solutions:

  • green impregnation
  • brown impregnation
  • oil-seed deep impregnation

6.3.4. Cutting

All parts for the assembly of elements are cut beforehand according to the detailed engineering design.
Minor cosmetic cuts are performed directly on the elements on the assembly line.

Cutting of beams

All beams are cut automatically with an automated saw.
The saw, a Weinmann WBZ160, is operated by one man and it cuts parts according to the engineering design prepared by Welement designers before production.

All parts are numbered and labeled as they are cut.
Cut parts are then moved to the assembly area.

Cutting of boards

All boards (gypsum, chipboard, ...) are cut manually on a cutting bench operated by one man.
Cut parts are then moved to the assembly area. factory review welement cut bench

Chipboard cutting workstation.

Cutting of excess cladding from the elements can be performed using a multifunctional bridge (see below).

6.3.5. Element Assembly

Elements are assembled on 2 parallel production lines.

Frames are assembled manually by 2 men. 
Once the frames are assembled, additional layers and insulation are installed. Then the elements proceed to the multifunctional bridge where men install the boards. factory review welement element

The main functions of the bridge are:

  • nailing of cladding, chipboards, gypsum boards (with screws);
  • cutting of excess cladding or boards;
  • marking of lines for eventual manual operations.

The bridge guarantees a constant and optimal quality of the product. The bridge is programmed by Designers to install screws/nails or to perform precise cuts or markings.

6.3.6. Element Handling

The two framing lines and the multifunctional bridge line have automatic belt system for moving the elements along the line.

The framing lines are equipped with butterfly tables that allow moving one element from one line to the other, flipping it on its back.

This way workes can install layers of both sides of the elements without the use of a crane. factory review welement assembly butterfly table

 Butterfly table in action. factory review welement line

Automatic belt system.

After assembly, elements are moved out the production line with a "trolley" operated by just one person.
The trolley can drive the element to the area where windows are installed or to a temporary storage.

Trolley operations are extremely efficient in terms of time and resources. 
In fact, moving the elements with a crane takes more time and it usually requires 2 or more men.

6.3.7. Packing & Loading

All elements and materials that need to be delivered to the construction site are packed with plastic film and plastic ropes.

Packages have a wooden base to avoid the elements being in direct contact with the ground.

The packaging is weather tight and packages can be left outside for days without any risk of damage to the content.

Packages are planned following the scheme assembly scheme for the on-site operations.
This way, elements that will be installed at the same time are most likely found in the same package.

Each package comes equipped with shipping list indicating its content and weight.

Important: delivery trucks are loaded inside the factory. This gives additional protection from exposure to bad weather.

6.3.8. Quality Monitoring

The quality of the elements produced in the factory is constantly monitored by registering the measures of each element or part assembled. Moreover, each layer has its own quality marks.
Measures and additional quality marks are inserted into an application that logs them for further reference.

In addition to that, workers are trained to control the product every time it is given over to another workstation.

Finally, at each workstation, the work executed is documented with a photo.

6.3.9. Time Monitoring

Time monitoring is executed in parallel with quality monitoring, by the means of the logging Application.
The analysis of logged times provides an accurate picture of the efficiency of the production process.

The Management uses these data to make strategic decisions to improve the efficiency of production.

6.3.10. Planning & Logistic

The sequence of production of elements, packing, loading of trucks is planned by the Production Manager in the Factory Office.

Planning takes into account availability of material, design, deadlines, interference with other projects.

6.4. Shipping

Shipping is organized by Welement as per terms agreed with the Client during the Sales process.
Generally Welement ships its goods DAP.

Welement allows Ex Works delivery for Clients who want to provide their own transport.

In any case, trucks are loaded by Welement at the factory.
