Industial laminates = composites = Isolants

Why use machined parts made of Isolants?
Machining is often the most cost-effective way to produce parts in small to medium batches. A wide selection of materials is available and machining offers great design flexibility without the high costs for tools associated with stamping.
The dimensions and construction of components can be changed relatively easily without excessive costs. Industrial laminates are not suitable for forming complex shapes, so machining is often the only practical way to produce complex parts from these materials.
PWR Composite combines the technical possibilities of modern CNC equipment with long-term experience in machining of composites.
Parts made in PWR Composite are now used in a variety of implementations, ranging from train components to furnace insulation components, traction line components, single-purpose machines to medical devices and machining center parts.
Thanks to its approach to each order, PWR Composite can produce batches of large or low volumes, but also individual unit orders.

Tolerances

Laminated insulators have their own particulars, which are reflected in the achievable tolerances after machining. 

Tolerance for hole diameters ±0,05 mm
Hole spacing tolerance ±0,01 mm
Length tolerance ±0,05 mm

 

Dimensional options of machined parts:

Turning :                                   Ømin - max = 1 - 500mm, active length 660mm

Milling :                                     1000 x 660 x 400 mm

Shape milling of

thin materials or engraving:   1200 x 2500 x 120 mm  (a tolerance of ± 0.1 mm must be taken into account here) 

 

Production takes place on the basis of documentation supplied by the client, preferably in the form of blueprints and 3D models. From the initial phase of demand, PWR Composite communicates potential bottlenecks in terms of manufacturability, usability of materials, requirements of standards, etc.

 

For correct pricing, it is necessary to supply the following information / documents:

Necessary:

2D blueprint or sketch with required dimensions,

Required material,

Quantity.

Recommended:

3D model in stp or iges format,

information on whether the project is a one-off or recurring,

packaging requirements,

other specific requirements,

required order currency.

 

Samples:

 
The parts are used in electrical engineering, energy, transport technology, aviation, in furnace production and in many other sectors.

Eg.: Electrical insulating and mechanical parts for rotating and non-rotating electrical machines, wedges (groove closures) for stator and rotor windings of electrical machines, parts for electrical devices, covers for Wi-Fi antennas, switchboards, transformers, insulation templates, slides, machine and tool pads, handles , RC cores, electrical insulating parts for traction vehicles, contactor extinguishing chambers, parts for traction vehicle electronics, insulators and insulator covers, insulating rods, base plates and insulating elements for welding jigs, worktops for tables and machining tools, ...

Machining demand

Repeated production:

- 3D model is not mandatory. It serves to better visualization of the requested part and to fasted price calculation especially for complicated parts.
- Technical specifications are not mandatory. If they will not be attached to RFQ, the drawing is the base.
