PET PVC Foam Core Kit Manufacturing Machines for Wind Turbine Blades
In the wind turbine blade, PET foam, pvc foam is a popular lightweight core material. The entire PET foam core kit production process can be divided into four main steps
1. Raw material extrusion process
2. PET foam Welding and slicing
3 PET foam machining Kitting &.finishing
4. Foam core shaped parts(geometic parts)
1. The PET Foam extrusion process requires less equipment and will not be discussed here for the time being.
2.Welding and slicing:
A. PET foam block welding machine is required to weld the original sheets after the extrusion process together into a huge block. Many kitting facilities start to kitting and machining only after getting this big block from manufacturers such as 3A Composite, Armacell, Diab or Gurit in the past few years.
B. Slicing machine(PET FOAM vertical cutting machines) cuts big PET Foam into 20-80mm PET Foam boards. Through the two processes of welding and slicing, the texture structure of PET foam is changed so that the closed cell core material meets the requirements of wind turbine blades.
3.Kitting and Machining.
Closed cell foam core and honeycomb core material used in wind turbine blade usually need the following procedures: grooves, perforations, scrims, contours, four sides trimming, sawing, chamfering and routing.
A. PVC PET foam board four edges automated cutting machine, CNC trimming machine
After slicing, the rough PET BOARD needs to cut off the excess edge to obtain a standard size Foam board (PET PVC Foam 1220mm*2440mm, balsa wood 610mm*12200mm. 5 saw blades working at the same time simultaneously Productivity is 10m³ (353 Cubic Foot) in per hour. The production efficiency is much higher than other machines or 5-axis engraving machines.
B. Double-sided dust collector, hole sealing machine, foam slot milling machine, and PET foam punching machines.
Through the above equiment, composite foam can be more perfectly integrated with the resin, enhancing the mechanical properties of the composite core materials.
C. PET Foam core material automatic cutting saw (PET Sheet to small parts) foam cutting continuous production.
This automated machine is tailor designed for composite core kit cutting PET foam sheet (Max width 1250mm), PVC foam sheet (Max1250mm). Cutting standard sheet into small parts and irregular parts.Stack sheets can be cut one time, max thickness 220MM.
The productivity have a significant improvement than other machining equipment.
Before this procedure, the workers need to paste the scrim fabric on the PET or PVC foam board.
D. PET foam panel slicing, Bevel cutting and Chamfering
D1 PET foam slicing machine.
Slicing thick foam panel into thin sheet, for example, 30mm foam panel spliting into 5pcs 6mm thin sheets.
D2 Automatic PET foam bevel cutting machine PVC foam core chamfer machine.
Designed for sandwich core kit bevel chamfer such as Balsa wood, PET foam, PVC foam Honeycomb.
Max Chamfering width: contour PVC PET sheet (with deep groove, leave bottom 1mm) 400mm, other plain foam sheets 200mm
The productivity have a significant improvement than 5 axis CNC routing machine.
D3 Automatic bandsaw bevel cutting machine PET foam PVC foam core chamfer machine.
Designed for sandwich core kit bevel chamfer such as Balsa wood, PET foam, PVC foam Honeycomb.
Max chamfering width: the width of the bevel is max 500mm.
The productivity have a significant improvement than 5 axis CNC routing machine.
4. Foam core shaped parts(geometic parts).
Specific 3 axis 4 axis 5 axis foam core CNC routers.
The shaped foam core kit are widly used in wind turbine blade and marine mold closing procedure
After our APPOLO plan, CCS released more chamfering machine, perforating machine, grooving machines, pls conact us to get more parameters.
CCS core cutting solutions has researched and designed different machines in each production procedure of composite core material . Compared with expensive five-axis machines, our equipment combination greatly improves production efficiency and is a good helper for core kitting facilities.
