Radius Forming FAQ

What does the PT Radial forming machine do?

The PT Veneer Former was developed as an economical alternative method to easily and accurately manufacture curved laminates such as arched headers and radius moldings for windows and doors, furniture parts, etc without the need to make large forms.

What is the advantage of the PT radial forming machine as opposed to making a individual form?

The PT Radius veneer formers can produce a wide range of shapes such as half rounds, ellipse and other radial forms all from one machine bed without the need to make individual forms or templates for each shape as is the case when making radial forms using the conventionally method. The PT range of machines take up very little space when compared to the traditional method of making and storing forms and templates.

How fast is setup on the PT radial forming machine?

Set-up is very fast, the standard PT7 radial forming machine comes with one machine bed and with adjustable forms and clamps (normally 32 of each) which are attached to the machine bed. The bed of the machine consists of a series of rails which have measuring tapes attached to each rail. The forms and clamps can be moved along the length of the rail according to its required position depending on the shape being formed. A computer program which is compatible with micro soft windows is supplied with the machine, the software will lead the operator through a series of questions such as type of shape (half round, true ellipse, etc) this will determin the proper set-up of the machine. This program will then display at what position on the rails each form and clamp must be positioned. Spring back is also taken into consideration in the computer software calculations. Set-up on the PT6 model is much faster as the positioning of the forms are moved on the machine bed automatically via numerically controlled stepper motors, the clamping of the form is also automatic. Curing on the PT6 machine is via Radio Frequency. On the standard PT7 machine an average of 2 to 3 Radial forms per hour can be made, and on the PT6 machine an average of 10 radial forms can be manufactured per hour.

How are the forms cured?

The form can be cured by different methods according to which model and with what options PT radial forming machine is purchased. Generally there are three ways to cure the forms. Ambient heat which would be through normal room temperature. Heat bands which would be a heated band which is placed around the form on both sides, inside and outside of the form. Radio frequency which only takes a matter of minutes to cure the form.

What sizes do the PT machines come in?

The machine beds on the PT7 come in different widths and length, for example widths of 4ft 5ft 6ft and the length can come in 8ft 10ft 12ft. The minimum inside diameter on the PT7 is 12″ and the maximum would depend on the bed size. The Bed size on the PT6 is 8ft x 8ft and the minimum diameter is 16.5″

What type of wood are the forms made from?

The forms can be made from any species of wood, generally the wood parts will vary in length and width according to the forms dimension required. The wood is normally made from multiple 1/8″ thick solid wood veneer slats which are produces on our Thin cutting frame saws (see web site). These 1/8″ veneer slats are face laminated to the thickness required on the PT machine and then formed into the shape required. Once the form has been made and cured it is machined and gives the appearance of a solid wood part.
