extrutec announces North American cooperation with WEFA

Posted on | by extrutec

Lake Constance-based WEFA and extrutec have announced their cooperation for the North American market as part of press coverage in the April issue of Light Metal Age.

Uwe Günter: "Agreeing to work together was a logical step for us. WEFA and extrutec share a common philosophy of developing and distributing products with the highest quality standards for high-tech requirements. Likewise, both companies are firmly rooted in the aluminum extrusion industry."

WEFA started in 1972 as a subsidiary of Alusuisse. After a change of ownership and strategic realignment, the company specialized in the production of aluminum extrusion dies. These are used in the automotive and construction industries as well as in electrical engineering, among others. With the development and patenting of its own coating process, WEFA succeeded in becoming the world market leader in the field of CVD-coated tools. Customers include not only leading aluminum groups but also innovative medium-sized extrusion plants. Today, the company manufactures at five locations worldwide (Germany, Switzerland, the Czech Republic and the USA) and employs more than 250 people, including around 130 at its headquarters in Singen.

The agreed cooperation includes mutual support in the North American market. This includes a joint sales concept, mutual support in the development of various products and applications, and ultimately a physical presence at WEFA's U.S. location in Cedar Springs (MI), where extrutec will open an office.

Double inline furnace order from Grupa Kęty

Posted on | by extrutec

extrutec has received an order for two inline furnaces from Aluform of Tychy in Poland, a company belonging to Grupa Kęty. The two furnaces will be installed on the 16MN-7" and 44MN-12" press lines.

The two Ovens ordered are the Inline Oven 2.0 which can only be offered worldwide by extutec. The revised 2.0 version of the inline furnace world patent includes considerable further developments and is no longer comparable with the previous version.

Sales Manager Ulrich Bucher expects many more orders for the improved inline oven before the end of this year. Bucher: "The technically significantly improved version of the inline oven sets completely new standards in terms of process reliability and energy efficiency. Despite the Corona crisis, we are receiving a large number of inquiries worldwide for this extrutec product.

The installation of the two inline furnaces is scheduled for December 2021.

extrutec receives largest single order in company history

Posted on | by extrutec

extrutec continues its positive course despite the ongoing Corona crisis and is rewarded with the largest order in the company's history by HAI Ranshofen.

Uwe Günter: "We have not sat back at any time during this severe and ongoing Corona crisis and have, among other things, invested more in product development. This positive attitude has now been rewarded. I would like to thank the entire extrutec team and our customers for their confidence in extrutec products.

The order from Hammerer Aluminium Industries in Ranshofen includes the supply of all key components upstream and downstream of the extrusion press for the new 60MN-12" press line.

A gas-fired rapid heating system with integrated Eco Shower Unit (ESU) and connected hot log saw will be supplied. This is complemented by a "stand-alone" induction furnace with a clamping system for frictionless billet handling in the I-furnace axis. The entire billet transport is done with a 2-axis overhead manipulator. A taper quench is also included in the scope of delivery.

In addition, extrutec also supplies a total of 5 gas-heated hot ageing ofens with side-opening doors and two service shuttles. Also included in the scope of delivery is an electrically heated overhead die heating furnace and an electrically heated 1-chamber chest furnace for preheating printing plates.

In addition, a new vertical magazine with crane track and crane bridge was ordered. The vertical magazine is designed for a maximum number of 180 bars.

Furthermore, a profile cooling unit equipped with the latest patented development, Alpha Flex Technology, will be supplied.

The installation of the complete line will start as early as May 2022.

First extrutec order for a new furnace at Hydro Hoogezand

Posted on | by extrutec

With the commissioning of extrutec as supplier of a new gas furnace system for the existing 7" press line by Hydro Hoogezand, a first order of a new installation for the Hoogezand site could be won.

In addition to a particularly high energy efficiency, the installation is characterized by a relatively high throughput of 3,700 kg/h for a 7" press.

The installation of this line will take place at the end of 2021.

extrutec delivers inline furnace to Gutmann AG at the end of 2021

Posted on | by extrutec

Gutmann AG, based in Weißenburg, Germany, has ordered an inline furnace with hot saw from extrutec for its existing 8" press line. This is the first inline furnace within the Gutmann Group, after several gas-fired billet heating systems have already been operated within the group.

In the course of the replacement investment, the existing long-stroke press will also be replaced by a modern 8" front-loading press.

The energy efficiency of the entire plant is a particular focus of this project. Therefore, the Eco Heating Process (EHPTM) developed by extrutec will be used. The EHP describes the use of different extrutec technologies in one line, consisting of the Eco Shower Unit with connected inline oven.

Thanks to the consistent use of the energy sources employed and the implementation of the technologies in a continuous process, it is possible to achieve a particularly high degree of efficiency (up to 75%) and thus a production process that is as low in CO2 emissions as possible. Another advantage of the EHPTM is the space-saving arrangement of the plant components, which is a decisive advantage especially for replacement investments.

Commissioning of the entire plant is planned for the turn of the year 2021/2022.

 

The Eco Heating Process (EHPTM) in detail:

In the first process step, the aluminum bars are preheated to temperatures of up to 90°C by laminar wetting of the entire bar surface with hot water. The Eco Shower Unit (ESU) uses the residual heat from the exhaust gases of the gas furnace and generates the required hot water in an air-water heat exchanger developed in-house. In constellations with pure gas-fired convective heating, it is also possible to use the heat generated for the ESU. (For more information about the ESU click here.)

 

After preheating by the ESU, the aluminum bars then enter the high convection preheating zone of the gas furnace. Here, they are further exposed to exhaust gases from the furnace's firing zones and heated up to 200°C. In the further process, the bars are then heated in the gas furnace to e.g. 400°C. In the induction module, which is directly connected in line, the required taper is supplied up to a head temperature (e.g. 480°C) for the optimum pressing process.
