Tool-Temp AG high-performance partner of Stüdli Plast AG

Tool-Temp AG spoke with Ardit Kamberi, Technical Manager of Stüdli Plast AG, about the temperature control of injection moulds, the challenges in the production process and the development of the plastics industry.

Stüdli Plast AG, based in Romanshorn, Switzerland, has been supporting industrial customers in the realisation of technically demanding innovations in various industries since its foundation in 1954. Decades of tradition and the expertise gained from a wide range of projects make Stüdli Plast an innovative and efficient partner for all needs relating to plastic injection moulding. With its subsidiary Grischa Plast AG, Stüdli Plast has built up an even stronger sales network, which offers customers considerable advantages. The temperature control units of Tool-Temp AG are used throughout the production of plastic parts. A large number of units are already in daily use.

For many years Tool-Temp AG can count the company Stüdli Plast AG among its valued customers. Four TT-142 N pressurised water units are in daily use and recently a TT-54’500 cooling unit with a cooling capacity of 54 kW was put into operation.

 

1. What exactly is tempered at Stüdli Plast?

Injection moulded plastic parts weighing 3 – 3000 grams are tempered. The temperature range to be covered is between 140 °C and 220 °C. In addition to the heating function, cooling also plays a decisive role so that a constant temperature of 10 °C can be supplied to the production process and maintained. This is achieved with the Tool-Temp cooling unit TT-54’500.

2. What is the challenge of producing plastic parts?

Customer requirements are becoming increasingly greater. In addition to function, appearance is becoming more and more important. Producing a finished product from the granulate that meets the customer’s specifications is a major challenge. This requires reliable functioning of the peripherals, such as temperature control units. Only then can the narrow process windows be adhered to.

 

3. How has the plastics industry developed since your company was founded in 1954?

The plastics industry, like many other industries, has become much faster moving due to globalisation. Only a few weeks are needed from the 3D drawing to the finished product. The digital tools enable an almost perfect visualisation of the problems that could occur in the real process. In this way, these problems can already be counteracted in mould making. In recent years, the sustainability of the use of resources has developed significantly.

 

4. How do Tool-Temp units simplify your production process?

Due to the integrated controller and the strong pump power, the Tool-Temp units are easy to operate, reliable and very robust. This guarantees us a safer production of the products.

 

5. We are very grateful for our long-standing good business relationship. What brought you to Tool-Temp years ago?

The flexible and targeted cooperation led us to Tool-Temp. In addition, Tool-Temp is located close to Stüdli Plast. Tool-Temp has always been a high-performance partner for Stüdli Plast, even in situations where everything must be done quickly.

Tool-Temp devices strengthen core competence of Sidrag AG

Tool-Temp devices strengthen core competence of Sidrag AG

Tool-Temp AG spoke with Eugen Vigini, Managing Director, and Luis Gil, Foundry Manager, about the temperature control of casting tools. The challenges in the production process and developments in the industry were also discussed.

Sidrag AG is known as an experienced supplier for small and medium series in Switzerland. Based in Baar, Switzerland, they have been successfully producing die-cast components made of aluminum, magnesium and zinc alloys from a single source for many years. In 1998, the range was expanded to include the multifaceted material magnesium. Sidrag AG was honoured with the Innovation Award by the Canton of Zug for this successful pioneering achievement. Sidrag AG is characterised by outstanding quality, flexibility, short response times and just-in-time deliveries. In addition, the company takes care of the entire implementation of the value chain for the components in question.

 

The experienced supplier Sidrag AG has been one of Tool-Temp’s valued customers for more than 25 years. Over 13 temperature control units are in daily use in the die casting foundry. “Simplicity, trouble-free, user-friendly, the units are optimally integrated into the manufacturing process” says Luis Guil, Foundry Manager at Sidrag AG.

Tool-Temp devices optimise and stabilise the manufacturing process for Sidrag’s most important industrial sectors, such as medical technology, measurement technology, optics, the construction supply industry, sensor technology, and the electrical and electronics sectors. An extremely positive development has been seen in recent years in lightweight construction, namely optics and medical technology.

Mega- or gigacasting – the production of oversized die-cast parts – is becoming increasingly important in the automotive industry, especially in vehicle body construction. However, this does not affect Sidrag, which specialises in the production of small and medium series outside of the highly competitive automotive sector. The focus lies on the development and optimisation of the classic casting cell. Throughout the casting process, the equipment is networked with peripheral devices, resulting in increased automation. This substantially increases productivity, reduces costs and creates a 30 % higher degree of staff independence so that freed-up time can be used elsewhere. Another advantage of a higher degree of automation is more consistent production processes with optimised cycle times, less waste and thus a high quality standard.

TT-388/2 equipped with time switches and other additional features according to customer requirements

Sidrag AG uses very small die-casting moulds with sizes from 200 x 200 x 200 mm to 800 x 800 x 800 mm. Parts with weights of 3 – 4 g up to max. 3 – 4 kg are produced. The units are used for tempering mould inserts, mould frames, slides and nozzles.

Sidrag’s challenge and core competence is its huge knowledge in the casting process and the processing of aluminium, zinc and magnesium. Sidrag is particularly challenged in the production of magnesium components; this is because liquid magnesium with a melt temperature of 650 °C hardens twice as fast as aluminium and therefore requires a high flow rate. In order to achieve stable temperature control and good heat dissipation, it is essential to have higher mould temperatures and the largest possible mould channels to optimise flow. Therefore, eight 2-circuit oil temperature control units from Tool-Temp are used on several die casting machines. From different device generations, the TT-370/2, TT-380/2 to TT-388/2 perform at the highest level at continuous temperatures of 240 to 280 °C. The powerful and high-quality 2-circuit units guarantee stable temperature control and trouble-free continuous operation, even under tough everyday conditions, especially in the die-casting industry. The easy application of the units and their usability are appreciated by the employees. The equipment, which is fitted with time switches at the customer’s request, in addition to various other additional features, ensures an even greater user-friendliness. Thanks to the pre-programmed, autonomous unit start, the heating process is already complete by the beginning of the shift.

Tool-Temp offers customised solutions to optimise production processes. Especially for Sidrag’s magnesium application, five TT-168 E/PHE temperature control units were modified for operation with heat transfer oils. Here, only nozzles and individual slides are cooled between 20 – 40 °C. Due to the high melting temperatures of the magnesium of 620 – 640 °C, a very high cooling capacity is required to dissipate the heat.

Tool-Temp supports its customers with comprehensive services from a single source. Sidrag AG is also very satisfied with the services, which fully meet their expectations. Particularly important are the short delivery routes, the permanent availability of spare parts with fast delivery times, as well as the fast response times with customised support and solution proposals.

“The geographical location of the company, the highly competent contacts who are available to us whenever we need them, either in the sales, service or spares departments had been instrumental in our long standing supplier customer relationship which continues to this day. The high quality materials and the experience with Tool-Temp equipment is unrivalled”, concluded Luis Gil.

Macrocast GmbH relies on accurate and reliable Tool-Temp temperature control units

Macrocast GmbH relies on accurate and reliable Tool-Temp temperature control units

Tool-Temp spoke with Jens Paul, Technical Manager of Macrocast die casting foundry, about the tempering of their moulds, the challenges in the production process and the development in foundries. 

Marcrocast GmbH is a specialized die casting foundry based in Samstagern on the upper side of Lake Zurich in Switzerland and is an affiliated company of Franz Binder GmbH & Co. El-ektrische Bauelemente KG in Neckarsulm, Germany. One of the core competences of this successful Swiss company is the production of complex zinc die cast components, mainly with mechanical CNC finishing, and specialises in the production of small components as well as small series. Macrocast is one of the renowned manufacturers for connectors with its vertical range of manufacture and produces most of the zinc die casting series for the Binder Group (65 %).

 

Tool-Temp AG is proud to count Macrocast among its valued customers for many years. Ten oil temperature control units are in daily use in this die casting foundry and recently a large TT-216’000 cooling unit with a nominal power capacity of 216 kW was put into operation for the entire die casting foundry. We visited Mr. Paul and asked him a few questions. 

1. What exactly is being tempered at Macrocast? 

Steel moulds weighing 120 – 180 kg are tempered. The temperature range to be covered is 90 °C for large- or thick-walled die castings, and up to 200 °C for very thin-walled die castings that require high and fast flow properties. An average of 4 parts per cycle are produced in the tool sizes used.

2. Zinc casting is suitable for countless applications, from simple window fittings to complex electronic components and automotive components to spectacle cases. To which industry do your biggest customers belong? 

The die cast parts are mainly supplied to the electrical industry and drive technology. Brackets and fittings for doors or windows are also produced for the fastening industry. 

60 – 70 % of these die cast parts are exported and approx. 30 % are produced for Swiss customers. 

3. How has your industry and applications developed in recent years? 

Many die casting foundries are following the trend and investing in Megacasting, the joining of several components into one die cast part. It has the potential to revolutionize the manufacturing process of automobiles. Since Macrocast specializes in small-series parts and produces small parts, Megacasting is not done. There are no such changes coming in the casting process for small parts. The more cavities a mould has, the greater the challenge to ensure that all castings in the same production cycle are cast in perfect and equal quality. 

However, there is a clear trend towards connectivity. Connecting the temperature control unit to the machine control system simplifies the production process significantly and is indispensable in terms of quality assurance. The temperature controller ensures that the die cast parts are produced without quality problems. 

4. In what way do Tool-Temp units simplify the production process in your die casting foundry? 

The greatest risk in the production of die cast parts is material doubling, which can occur due to cold fronts during casting (too low casting speed leads to premature solidification). Especially with thin-walled castings, material doubling is particularly visible and cannot be accepted. The solidification temperature of zinc is 387 °C and therefore, Macrocast relies on Tool-Temp oil tempering units, by controlling at high temperatures. 

Our goal is the continuous optimization of cycle times, and this is achieved by using the Tool-Temp oil temperature control units TT-248 (up to max. 200 °C), TT-288 / MP988 (up to max. 250 °C). 

5. How many hours are the Tool-Temp units in use every day? 

We use the units for 13 hours per day (at the end of the shift the units are switched off), but they can easily be used in 24/7 operation. 

6. We are very grateful for our long-standing good business relationship. What brought you to Tool-Temp years ago? 

More than 6 years ago, employees came across Tool-Temp through internet research. Since the focus was on independence, individual solutions, quick communication channels and fast availability of equipment and spare parts, it quickly became clear that Tool-Temp would become the business partner. 

7. What are your experiences with the Tool-Temp units? 

The temperature control units are very reliable, this is proven by their control accuracy. They easily withstand the rough everyday conditions in die casting.

With very small cooling bore cross-sections, there is the difficulty of heat dissipation, and this can be easily compensated for by higher tool temperatures. Macrocast relies on the robust Tool-Temp oil temperature control units. The uncomplicated system design makes the units easy to operate. 

8. Are you satisfied with the performance of the units and the Tool-Temp service? 

We appreciate the very short reaction times and solutions from Tool-Temp-After-Sales and are pleased to confirm that we have not had any production downtimes with the use of Tool-Temp temperature control units. 

We are very satisfied with the unit’s performance, consequently, when we wanted to mod-ernize our cooling system a year ago, it was also clear to us that Tool-Temp would offer a solution tailored to our requirements. Since then, the TT-216’000 cooling unit has provided the cooling water supply for the entire die casting system and all temperature control units.
