1. SIMAX Glass:

This clear borosilicate glass falls into a group of types of glass, which excel in a high heat and chemical resistance and which have been defined by international ISO 3585 Standard. These types of glass may be utilized in the most demanding sectors, such as chemistry, pharmacy, medicine, biology and food industry.


2. Raw Materials Preparation and Melting:

In a modern automatied blending plant pre-treated and blended raw materials are melted in electric resistance furnaces with vertical melt flow and continuous operation. Electric glass melting in Kavalierglass has a 30 years tradition and by the extent of use it is unique worldwide.


3. Mechanical Productio by Blowing

Rotary glass blowing automatic machines from thin-walled vessels (such as beakers, flasks, tumblers and jugs) from a glass drop, impinging from within an automatic feeder. The drop, placed inside the machine on a ring washer, falls through the washer opening and it is stretched partly by its own weight, but above all, by the effect of air pressure from the glass blowing ahead, and, it rotates on vertical axis. The glowing flask is gripped all around by two parts of the glass mould, which has the shape of the final product. By an increase of air pressure the product in the mould takes shapes, and, upon opening the mould, it slides down in a conveyer. In forming, a technological edge, called coat, is created an glass blowing machines. This coat may be removec inside another machines by melting away. The production line is automatically connected to automatic machines for spout forming and decorative or functional glass printing machines and forming and printing of such kinds of products, as may be required.


4. Bottles Mechanical Production

For the purpose of manufactoring special bottles and jars for medicine or  laboratories, where using Simax glass is advisable or essential, Kavalierglass utilizes a modern automatic machine.


5. Mechanical Pressing:

The glowing glass mass in the feeder creates a drop at a temperature of about 1.300 degrees Centigrade, which falls down, when automatically cut off, into a pressing mould, and, it shall be pressed out in no time using hydraulic pressure. On the one hand, the pressed piece shall be cooled down at press further positions, and on the other hand, it shall be smoothed down and polishes by a system of burners. The pressed piece shall be transported by a cinveyer bellt to the hardening fumace (the tunnel), where after a new heating, it shall be suddenly chilled by air flow and face hardened. Thus its heat resistance shall be increased in 50 percent and the product shall acquire the required proporties for all usual heat treatments in the laboratories or at home.


6. Glass Tubes Mechanical Production

Technically demanding modern automatic production of borosilicate glass tubes as semi-finished products (blanks) for further processing represents a prerequisite for a successful production of a whole range of assortment of laboratory instruments and industrial glass equipement. For the production of glass tubes with a diameter of up to 50 mm Kavalierglass utilizes an up-to-date Vello system drawing line, and glass tubes with lager diameters up to 170 mm are drawn on the equipement of the glass works own design.


7. Glass Manual Forming

Laboratory and technical glass assortment manufactured in Kavalierglass includes thousands of kinds of products. This is why there are still hundreds of types of products, which are required to be hand-made due to complexity of the form or because of a limited production series. The plant, however, employs glassmakers, who are highly-qualified and skilled in terms of craftmanship, and, who are able to handle any problem in glass manual forming, be it a modern pan for chicken dietetic grilling or a 200 litres reactor vessel. Using hand-operated mechanical and hydraulic presses, and, afterblowing the largest products, which are complex in shape, by means of compressed air puts away physical strain and facilitates the glassmakers' work. Likewise, finishing operations on manually formed products are made on modern machines, which, as a rule, are of the glass works own design and manufacture.


8. Glass Blowing Production

Glass forming above a blast lamp remains to be the basic technology of each manufacturer of laboratory instruments. On a daily basis, tens of skilld glass blowers in Kavalierglass produce with accuracy and precision even the most complex laboratory equipement and instruments in accordance with drawings and standards. In this activity they make use of mechnically formed glass semi-finished products (blanks) and above the blast lamp they weld not more than just the instrument final assembly. Whole range of operations in glass blowing technology has also been mechanized. Semi-finished products, such as namalized ground glass joints, glass taps and others, are produced, in the first place. mechaniclly. Graduated cylinders production has been fully mechanized. A part of labortory vessels is required to be accurantly measured and the capacity has to be marked on he product in the prescribed manner. Marking may be performed for the most part using a fast enamelled printing, and, for the production minor part a more conservative process of making by glass etching is used on customer's request.


9. Large Vessels Welding

The finishing production of large glass storage tanks, reactor vessels and heat exchanges from the industrial glass equipement programm has proved to be extremely demanding. Flanges with a diameter of up to 600 mm are welded on the vessels to ensure the final assembly in a cold state, and, feed and outlet holes adapters, glass taps and bushings for thermometers and stirrers are welded on a defined place to the vessel. Multiple helices of heating and cooling coils are welded on heat exchangers lateral area of a cylinder.


10. Industrial Glass Equipment Assembly

At the end of the manufactoring process of industrial valves, the assembly is performed, druing which, using non-glass supplements and connecting parts, metallic flanges, bolts and packgings, the whole equipment shall be built up and subject to functional testing. On customer's request the manufacturer may also perfom a final asssembly and testing, eventually commissioniering the equipments at buyer's plant.


11. Product Completion

Household glass made in series production is sold in sets and assemblies, which are reasonably set up in packin the product. Assembly of non-glass elements and supplements also forms part of the completion. The completion operation is finished by packed products palettization and wrapping the pallet assemblies up in a stretching film. The film covered transport pallet as an up-to-date, highest stafety and economic product packing then represents the basic sales and dispach unit.
