Flexible
accordion guide shield (Plastic Bellow Cover) is a kind of shield machine. Organ of the shape of the shield can be designed according to the actual needs various styles, at the same time,
the size of shield can be made according to the actual needs. Shield (cover) for external use German
nylon fabric, with PVC board support, both ends load for a fixed metal skeleton
connection or plastic skeleton.
This kind of shield (cover) has
advantages of small compression. Product can be oil resistant, corrosion
resistant, hard objects collision deformation; Walking at the same time product
has long life, good sealing, stable, durable, etc. Using this kind of product
can bring perfect effect to the use of the machine tool. Shield (cover) inside
without any metal parts, don't worry about shield (cover) work when a loose parts and
causing severe damage to the machine.
The working speed of shield`s air bellows can reach 200 m/s. Flexible accordion guide shield (Plastic
Bellow Cover) has been
widely used in numerically controlled machine tools, electronic equipment,
stone machinery, glass machinery, door machines, injection molding machine,
manipulator, lifting transport equipment, automatic warehouse etc.
Structure of common Flexible accordion shield (Plastic Bellow Cover) material is as follows:
Plus material:
Nylon cloth or protective cloth
Support: PVC sheet
Connecting plate:
Resin plate, iron plate
Pulley: Copper or
nylon bearing

To calculate the dimensions of the welded
bellow at the design stage, it is useful to pay mind some date:
1.
The
standard folds have the following height: 15mm/ 20mm/ 30mm/ 35mm/ 40mm/ 45mm/
50mm;
2.
The
total play between the slides and the bellow must be from a minimum of 5mm to
maximum of 10mm.
3.
The
extension of one fold is equivalent to twice the fold`s height minus 10mm.
4.
The
thickness of a compressed fold is on average 4mm.
5.
The
compressed length of the bellows is equal to:
Extension of
bellow÷extension of one fold ×(3~4.5mm)+flange thicknesses
The following is the multi-purpose shields (covers) that can be used for
any types of machine or tools thanks to their various shapes and space-saving
design.

The report said that in 2012 the European machine tool industry showed good export performance and weak internal demand, and future growth will rely more on foreign orders.
The report said that the reduction in machine tool investment reflects the cautious attitude of European companies on the development prospects, especially in southern Europe. With the slowdown in European manufacturing, the number of internal machine tool orders in Europe is expected to decrease by 77 million euros ($93.33 million) in 2011.
Martin Kapp, president of the European Machine Tool Industry Association, said that the association's export orders in 2011 were close to a record 16.7 billion euros (about 21.5 billion US dollars). This year, it continued to maintain steady growth. The good export performance proves the competitiveness of European machine tools. Especially in the Asian, North American and South American markets.
The European Machine Tool Industry Association has called on the EU and EU member states to adopt positive policies to stimulate manufacturing growth. In 2011, about half of the exports of the European machine tool industry were sold to non-European regions, and the proportion of non-European regions continued to increase. Therefore, the EU needs to actively promote the conclusion of free trade agreements. The European Machine Tool Industry Association expressed disappointment that the European Union has postponed the signing of a free trade agreement with India, fearing that Japan and South Korea, which have signed a free trade agreement with India, will gain a competitive advantage.
The European Machine Tool Industry Association consists of 15 national associations representing nearly 1,500 industrial enterprises in Europe and Turkey, 80% of which are SMEs, accounting for 97% of the machine tool manufacturing capacity in the region and also accounting for one-third of the global machine tool manufacturing capacity.
