Plastic test mould  standards EN 12390-1

Plastic test mould is a necessary tool for highways, railways, tunnels, water conservancy, architecture, construction units, colleges and universities, etc. It has the advantages of low price, high precision, easy use and not easy to damage.
1. Light weight, the weight is 1/8 to 1/10 of the cast iron trial mold of the same specification, which reduces the working intensity of people.
2. The process of installing and removing the cast iron mould is eliminated, because it is a whole, it can be demolded with an air pump (or pump), and one person can demold quickly, which improves the working time.
3. The accuracy of the test piece is improved, because the plastic test mould is successfully injected with engineering plastic high-precision molds at one time, and the human error caused by the casting of the cast iron mould is reduced.
4. Engineering plastics have high strength, high temperature resistance and low temperature resistance, and can be used normally without deformation in the range of -35 ~ +100.
5. It can be used economically for a long time, with low unit price and reduced labor, and there is no trouble of replacing the bolts and nuts of the cast iron mold.

The main purpose

It is a necessary tool for highways, railways, tunnels, water conservancy, architecture, construction units, colleges and universities.
Main series Plastic trial moulds have the advantages of low price, high precision, easy to use and not easy to damage. Once launched, 
they are warmly welcomed by the majority of marketers and users. Plastic trial molds mainly include: 100 square, 150 square, 707 triple, 
100 triple, 100 × 300 elastic modulus, 100 × 400 frost resistance, 150 × 300 elastic modulus, 150 × 550 bending resistance, 100 × 515 bending 
resistance, 150 × 175 × 185 impermeability. And plastic sand filling cylinder and slump cylinder. The mold has the characteristics of wear resistance,
 corrosion resistance, small tolerance, no deformation for a long time, easy to use, convenient and so on.

Precautions

1. When using engineering plastics for trial test moulds, you should carefully read the technical manual, be familiar with the technical indicators, working performance, use methods, and precautions, and strictly follow the steps in the instrument manual.
2. For the first time to use engineering plastics to try molds, they must operate under the guidance of skilled personnel.
3. The engineering plastic trial mold used in the experiment should be arranged reasonably, neatly arranged, easy to operate, observe and record.

Technical parameter for Test mould

Engineering plastic test moulds are used to form special equipment for forming standard test pieces of cement, mortar and concrete. The formed test pieces can be used for compressive strength, flexural strength and other physical performance tests of cement, mortar and concrete. According to the structure, it can be divided into cube, cuboid, cylinder, cone type, according to the use, it can be divided into cement mortar test mode, mortar mould, concrete compression  mould, concrete antifreeze test mould, concrete bending mould, concrete elastic Modulus mould, concrete impermeabilitymould, etc., cube and cuboid mould can be divided into single and triple, cylindrical and conical types are divided into integral type and split type. The single-cube, rectangular parallelepiped trial mould consists of side plates and bases. The triple cuboid test mould is composed of an end plate, a partition plate and a base, and the sealed test mould is composed of a side plate, a cover plate and a base or an end plate, a partition plate, a cover plate and a base.
