• Design of production tooling for the given structure
• Optimization of the production process basing on the mathematical simulation
• Design, development and transfer of the production technology into the batch production

ApATeCh arched bridge production by vacuum infusion	ApATeCh sea wall production by vacuum infusion

Advantages of vacuum infusion production

• Minimal requirements for the equiment (the main equipment – vacuum pumps)
• Minimal power consumption and absolute safety of the production process
• Considerable reduction of costs and production price as compared to the prepreg tecnologies
• Opportunity to construct high-integrated structures in one manufacturing step
• No geometry and dimensions restrictions of the products
• GFRP volume content is more than 60%
• Plastic porosity not less than 1%
