With the deepening of the construction market reform, the market of all kinds of building template factory will be very broad, across the country are key projects and engineering requires a lot of development, such as rail, light rail, tunnel, bridge construction, all need to have a large number of different shape building template to use and supporting.

Enterprise only insist for a long time to consolidate and improve old products, and communities in scientific research innovation continuously introduce new products, to meet the needs of template and the construction market, firmly seize the new thought of reform and innovation, to win customers.

: 1, wooden template is made up of several layers of vertical and horizontal cross wood holds together by heating, main composition is urea formaldehyde glue or melamine and phenolic resins, concrete construction in wood template in the slurry alkali soaking water dissolve the glue, combined with the concrete hydration heat, easy to cause the wooden template layered dissection, general usage is 3 ~ 5 times, wooden template using late to produce large amounts of construction waste.

2, plastic template: is a mixture of PE and PP material, not high temperature resistant, easy to deformation, large brittleness, easy to aging, easily damaged, inflammable, static music intensity and elastic modulus (stiffness) can not meet the current national standard of building template;Although it can be recycled and reproduced repeatedly, the quality of each remanufactured product will be reduced by one level.

3. Aluminum formwork

(1) high one-time investment.

(2) high requirements for drawings of buildings and structures;In case of design changes, in the aluminum alloy template design and production stage, it is necessary to redesign the template, re-extrude the aluminum profile, and the cost of modifying the template is large.If it occurs during the construction stage, it is inevitable that some templates will not be used, and the cost of modification will be higher and the difficulty will be greater.

(3) considering the turnover times, the aluminum alloy template will increase the cost and prolong the completion time in the non-standard layer.
