PRECISION DISPENSING IN THE AEROSPACE INDUSTRY

Product catalog summary

Introduction
This document discusses precision dispensing technology in the aerospace industry, focusing on adhesives, sealants, core fillers, and more. It highlights the use of volumetric dispensing systems based on the Endless Piston Principle for handling various viscosities.

Technology Overview
The core technology involves a volumetric dispensing pump that ensures precise and pressure-stable dispensing. The systems are designed to handle a wide range of fluid properties, including viscosity, abrasiveness, and shear sensitivity, ensuring high dosing accuracy.

Core Competence
Key to product quality is the precise geometry between the stator and rotor and the selection of suitable elastomers, which are proprietary formulations for optimal operation.

Materials and Requirements
Materials such as polysulfide, epoxy resin, silicone, and polyurethane are discussed, with emphasis on their specific dispensing properties like shear sensitivity, compressibility, and viscosity independence.

Material Handling Systems
Efficient systems for emptying, supplying, and dispensing materials are described, with capabilities for handling viscosities up to 7,000,000 mPas and container sizes from 180 ml to 1,000 l.

Product Portfolio
The portfolio includes dispensers and pumps for various applications such as coating, filling, and spraying, with customizable systems based on process requirements.

Engineering and Consulting Services
ViscoTec offers comprehensive services from consulting to after-sales, ensuring systems are tailored to customer specifications and integrated seamlessly into existing processes.

Applications Overview
Applications include sealing wing shells, applying surface coatings, filling sandwich structures, and sealing rivets and screws, each with specific process requirements and benefits.

Sealing Over Time
Challenges of manual sealing processes are addressed, with ViscoTec's automated solutions offering improved efficiency, reduced waste, and better compliance with specifications.

Opportunities with ViscoTec
ViscoTec provides opportunities for optimization through demand-oriented dispensing, reduced logistical efforts, and potential for complete automation, enhancing process speed and accuracy.
