Our Business
World Class Infrastructure
Valdel AT has invested in state of the art equipment for manufacture of composites products and systems. These provide Valdel AT with versatile infrastructure to solve a wide range of problems for its customers. The existing facility at Peenya has 32,000 sq feet of space for manufacturing and support activities. On the cards is a much larger greenfield manufacturing facility, with 120,000 sq ft of manufacturing and support space, and with large autoclaves, C Scan machines and CNC machining centers.
VALDEL AT
The manufacturing facility has been designed keeping in mind the latest technologies with sophisticated equipment to design, develop & manufacture advanced composite products with consistently high quality. The equipment includes a Fully Automated Autoclave, Programmable Oven, Laser projectors, Laser trackers, Prepreg Cutter, Differential Scanning Calorimeter, Dynamic Mechanical Analyzer, and various other equipment required for design, research, prototype development as well as serial production. The Factory is also equipped with a state of the art ISO 7, Class 10000 Clean room.
AUTOCLAVE
AUTOCLAVE
Aviation and military components have stringent quality requirements. The factory has an autoclave from the Spanish Company Olmar, having a working diameter of 1m and working length of 1.4 m, with an operating temperature of 250°C and an operating pressure of 10bar ‘g’.
COMPOSITE CURING OVEN
OUT-OF-AUTOCLAVE COMPOSITE MANUFACTURING
The factory has expertise in manufacturing of products and components using Out-of-Autoclave technologies, using programmable composite curing oven and resin infusion techniques. Both these processes are NADCAP certified.
COMPOSITE CURING OVEN
Apart from autoclave curing, composites parts can also be manufactured by vacuum bag consolidation of CFRP and GFRP prepregs that are oven cured in controlled temperature and pressure. The facility has a composite curing oven of working area 6m (Length) x 2.5m (width) x 2.5m (height). Working temperature range is 250°C with close temperature control and uniformity.
RESIN Transfer and Resin INFUSION
RESIN Transfer and Resin INFUSION
The factory has a Graco PR70 from USA and Vacmobile Modular 2S, New Zealand for resin infusion. PR70 has a variable ratio from 2.5:1 to 5:1 for accurate metering, mixing and dispensing medium to low viscosity resins for potting, gasketing, encapsulation and syringe filling. The heavy duty Vacmobile Modular 2S equipment is used for high quality and controlled Vacuum Infusion.
PREPREG AND FABRIC CUTTTER
PREPREG AND FABRIC CUTTTER
The Zünd digital cutter G3 M-2500 from Switzerland has a working area of 1330mm (width) and 2500mm (length) with a provision for 3 tool module slots and a wide range of cutting tools for cutting prepregs, woven carbon and glass fibre, honeycomb and foam cores . The purpose of Zünd digital cutter is to accurately and consistently cut composites reinforcements. The Cutter uses nesting software to optimise material usage with minimal waste and increased productivity.
LASER PROJECTORS
LASER PROJECTORS
The factory has three LAP laser projectors from USA. Each individual laser projector has an operating range of 9m having an accuracy of ±0.1mm/m. The purpose of laser projector is to carry out accurate positioning and layer-by-layer placement of prepregs and woven fabric on mould for manufacturing aviation components and products. This provides much greater accuracy and control as compared to templates and eliminates operator errors.
LASER TRACKER
LASER TRACKER
The RADIAN (IFM+ADM), laser tracker from USA HAS a working range of 20m radius with an accuracy of 10µm. This Portable 3D measuring Coordinate Measuring Machine (CMM) is used to measure master moulds, tools and components made out of composites or metals needing close tolerances and/or complex profiles.
THERMAL ANALYSIS
THERMAL ANALYSIS
Differential Scanning Calorimeter (DSC 8000) and Dynamic Mechanical Thermal Analysis (DMA 8000) from Perkin Elmer, USA. DSC is used for studying resin cure process. DMA is used for studying physics and mechanics of polymer material under high and low temperatures (-150°С to +600°С).
OLYMPUS SCANNING MACHINE
OLYMPUS SCANNING MACHINE
The Olympus OmniScan SX from USA is used for carrying out Non Destructive Testing on composite components. The machine is capable of carrying out both A and C Scan testing.
Valdel Advanced Technologies has its in-house team of design and engineering professionals who have experience in concept design, material characterization, composite and metallic tool design, component and tool modelling using CAD, as well as reverse engineering. The Design Group also undertakes process design and creation of manufacturing documents such as work instructions, PFMEA sheets and Route Cards.
This capability is bolstered by the Techno Center Design Group of RUAS, which is well versed in Structural Analysis of composites and metals. The Design group can offer services in:
