INDUSTRILAS’ IP-CLASSIFICATIONS

IP54 = Dust protected and splash-proof This is considered the standard issue.
IP65 = Dust tight and water jet-proof The higher classification of intrusion protection is obtained by sealing for instance a lock’s housing with an O-ring and a flat gasket or a fixed gasket.
It should also be mentioned that Industrilas has a few other special classifications. Most noteable are products used in high-hygiene applications, for instance when our products are used in the food manufacturing industry:
IP69K = Dust tight and protected against close-range high pressure, high temperature water jets.

IP SEALING CLASSIFICATIONS

The Industrilas inventory features two main intrusion protection classifications. If a product is rated to seal at IP65 it has either been tested by an independent laboratory, or the product is so similar in construction to another tested product that it could safely be classified as IP65. However, it should be noted that it is the complete product that is rated for intrusion protection, including the cabinet or product that the item is built into. Industrilas AB can only guarantee that its products live up to their stated IP standards if those products are built in and used in a correct manner. The IP classification is designated by two numerals, with the following significance: the first number indicates the degree of protection against touch and intrusive objects; the second number indicates the degree of protection against intrusive water. The higher the number, the better the protection.

NEMA SEALING CLASSIFICATIONS

In North America intrusion protection is classified according to the standards of NEMA (National Electrical Manufacturers Association). If an Industrilas product is rated to seal at NEMA 4 it has either been tested by an independent laboratory, or the product is so similar in construction to another tested product that it could safely be classified as NEMA. IP65 roughly corresponds to NEMA 4, but the ratings are not directly equivalent between the two standards.

NICKEL PLATING

is primarily used on decorative surfaces and for corrosion protection, but also as a substrate for chrome, gold and silver plating. The baths usually consist of sulphates, chlorides and boric acid (= Watt’s solution).

O-RING

O-rings are often used to seal between handle and insert or housing in order to obtain sealing classification IP65 in Industrilas products. The O-rings used by Industrilas are often made of NBR (Nitrile Rubber), a material with good chemical resistance and very good oil durability. We can also supply products with O-rings made from other materials than NBR if you need a product to achieve UL-approval etc.

PASSIVATION

is a process whereby a protective layer is obtained on metals, especially stainless steel and copper, through submersion in an acidic solution. PHOSPHATING, an alkaline process that is performed to provide corrosion protection, a foundation for the lacquer coat, corrosion protection underneath a layer and/or to obtain lubrication. It is primarily iron and zinc that are given a phosphate coating. The most common methods of phosphate coating are, according to the content of the baths, iron, zinc and manganese, and they usually take place through spraying or submersion.

PLASTIC INJECTION MOULDING

Injection moulding is a manufacturing process for items in various thermo-plastics, or plastics that become liquid at high temperatures. The machine consists of an injection unit and a mould-closing unit, and a mould unique to each product or tool. The injection unit is fed with ground-up plastic through a funnel that leads to a heated cylinder. The melting point is usually between 175˚ and 300˚ centigrades.

The molten plastic is pushed forward with a screw that also functions as a piston. The molten plastic is portioned out and injected in the mould in an intermittent process. The mould is kept closed until enough plastic is filled into it and until correct pressure has built up (50- 150 MPa). Now, the plastic is cooled off, the mould is split open and the part is removed, whereafter the process is repeated.

Important factors are the temperature of the molten plastic, the pressure in the injection unit, the temperature of the mould, the cooling-off period, and the dimensions and design of the mould itself.

POLYAMIDE PLASTICS (PA)

Industrilas products are also manufactured through injection moulded Polyamide 6. The auto industry and makers of household appliances and office equipment are main users of PA due to its characteristics: wear-and -tear endurance; toughness; resistance to inorganic compounds, oils, greases, gasoline and organic solvents; can be sterilized with steam; and has a low friction coefficient. The standard Industrilas Polyamide 6 (PA6) is modified for toughness with various amounts of glass fibre reinforcements, usually 30% (GF30), to additionally optimize the characteristics of the product. Industrilas has chosen PA6 particularly for its high impact toughness and good mechanical characteristics. The temperature range for use of items made of PA6 is -30˚ to +70˚ centigrade. Industrilas also injection moulds items from other plastics, such as PC, POM, ABS, PP, PE and PS. Housings, inserts, handles, keys and hinges are all examples of products manufactured out of PA, even though all these items are available in other materials as well.

POWDER COATING

Industrilas aspires to control as many production processes as possible, and consequently in-house powder coating capability has also been obtained. The choice of method is based on several criteria, prioritizing product quality and environmental concerns. The preparation method is Bonderite, and the powder application is performed in a chamber with modern application equipment that charges the powder electrostatically. The applied powder is especially formulated for coating of porous items, such as die-cast or zinc plated steel, where the risk of blister build-up and pinholes are prevalent during the tempering process. The Industrilas standard powder contains polyester as a bonding agent, which renders the finished products extra resistant to bleaching by sunlight. After the coating the powder is cured for 20 minutes in an electrically heated furnace. The advantages of an electric furnace are primarily better process stability, and a less sensitive coating process of for instance light-coloured items.

PVC

Polyvinyl chloride (PVC) is one of the most common kind of plastic. It is a thermoplastic polymer made of several connected vinyl chloride molecules, and constitutes one of the basic plastics. However, a material that only contains polyvinyl chloride is rather stiff, so a softening agent is added to the polymer. The Industrilas inventory offers edge protection in PVC and so-called carriers of certain sealing profiles.

SILICONE

This is the collective name for basically inorganic polymers based on strands of silicon and oxygen. Silicon does not conduct electricity, does not dissolve in water and is relatively resistant to the effects of chemicals. The Industrilas inventory offers sealing profiles from silicone. These are separately stored and delivery will be after consultation with the customer.

SINTERING METALS

Sintering is the process of compacting and forming a solid mass of material by heat and/or pressure without melting it to the point of liquefaction. The metal powder is pressed into a mold in the shape of the detail. The pressing produces a so-called ”green body” containing a great amount of pores. In the sintering process the green body is heated so many of the pores are closed and the item takes on its ultimate mechanical characteristics. Sintering produces smooth surfaces, and items with complex shapes can be manufactured without the need for much additional work. This can be done with different materials such as stainless steel, and so on. Industrilas uses sintered items as for instance cogwheels and pinions.

STAINLESS STEEL

Certain demanding environments require a more durable material. The corrosion resistance of stainless steel comes from the steel being alloyed with chromium. When the chromium content exceeds approximately 10.5% a thin film is formed on the steel that passively protects the underlying steel from further oxidation, or rusting. In case of damage to the surface of the steel the top film of protective chromium oxide forms again very quickly. Industrilas has a large assortment of stainless versions of locks, handles and hinges. If nothing else is stated in the Catalogue, the classification ”Stainless Steel” refers to the European Standard EN 1.4301, which corresponds to American Iron and Steel Institute standard AISI 304. For complete material specifications see

V-0

The polyamide used by Industrilas (PA6) is reinforced with glass fiber for increased toughness. The amount of glass fibers varies, but is usually 30% (GF30). The polyamide may also be modified to fulfil the standard V-0 in accordance with UL 94 (flammability: self-extinguishing of the flame within 10 seconds). Industrilas use the PA6 particularly due to its high impact resistance and good mechanical properties. See also “polyamide”.

VDI 6022 Part 1 (2006-04)

The guideline series VDI 6022 applies to all air-conditioning systems, the rooms or common areas in rooms intended to be occupied by people more than 30 days per year or regularly for more than two hours per day. It applies to all equipment and appliances and their centralized and decentralized components (also HVAC-units such as cooling towers, which will affect the supply air). The Directive applies also in situations for air exhaust ventilation equipment when this may influence the supply air when using heat exchangers or similar.

Industrilas supplies products such as inspection windows for ventilation systems (HVAC-units) made of materials with the proof of the required microbial inertness according to VDI 6022. See catalog page 5-255.

ZINC

(Zamak 5, Z 410) The Industrilas product inventory includes die-cast items made of zinc. The alloy that is utilized is a mixture of zinc, aluminium, magnesium and copper. Industrilas uses the alloy ”Zamak 5” due to its superior qualities in the combination ease of casting/surface finish. Housings, inserts, handles, keys and hinges are all good examples of suitable die-cast products, even though all of these are also available in other materials. In certain demanding environments zinc is not the recommended metal, such as in a marine environment, or external vehicle components and situations where there is a risk of severe mechanical wear.

ZINC DIE-CASTING

Die-casting is a manufacturing process that involves forcing hot, molten metal into the mould cavity made from a tool, which in turn can have varying degrees of design detail. When the metal, under pressure, has solidified, it is ejected from the mould cavity and the item is finished. After vibratory deburring and drying it is ready for surface treatments. The primary advantages of die-casting are the ability to stay within precise dimensional requirements, cast intricate items with good strength and corrosion resistance, and obtain a fine surface finish.

ZINC PLATING

is the most common metal plating method, offering corrosion protection for steel items. The plating baths consist of cyanides in alkaline liquids.
