Valves, flanges require adiabatic, how to apply the valuation form

(1) Pipe valves, flanges need to be insulated (except silicate smear materials and fiber-like bulk materials), apply the corresponding items of cotton mat (by) products, only change the unvalued materials, The amount of works is calculated according to calculation rules. (2) ventilation pipe flange insulation: ventilation pipe insulation has been considered, shall not be counted. (3) Adiabatic components of ventilation ducts: In the calculation of heat insulation of ventilation ducts, the length of the valves and other components shall not be deducted, and the ventilation ducts adiabatic items shall be calculated according to the extension meters.

Plastic Mold

Plastic molds are tools that are matched with plastic molding machines in the plastic processing industry to give plastic products a complete configuration and precise dimensions. Due to the wide variety of plastics and processing methods, and the complex and simple structures of plastic molding machines and plastic products, the types and structures of plastic molds are also diverse.

Generally, a plastic mold is composed of a movable mold and a fixed mold. The movable mold is installed on the movable template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine.
