Polygonal mould for sheet press

Tools

• Sheet press set

• Angle grinder

• Welding tools and materials

• Jigsaw

• Sander (for product finishing)

• Safety gear: welding helmet, safety glasses, mask

• Marker

• Ruler

• Computer with drafting/drawing software

Materials

• Steel for mold: 0.79 x 0.79 inches (2x2 cm) galvanized steel (standard size = 19.7 ft)
• Clean, sorted plastic, type optional

Draw the polygon in your preferred drafting software to obtain precise dimensions for each side.

Measure your sheet press work area.

Offset by 2 inches (5 cm) inward for space around the mold.

Design the polygon based on your machine's capacity.

Offset by 0.8 inches (2 cm) inward for the steel thickness.

Use the drawing to measure the mold dimensions. This will aid in calculating the plastic required for sheet production.

After outlining and measuring, use an angle grinder to cut the 20mm (0.79 inches) hollow galvanized steel to the specified size.

Mark dimensions using an erasable marker for accuracy. Employ an angle grinder for cutting. Use a whiteboard marker to draw a 1:1 template of your sheets to align angles and dimensions properly, adjusting as necessary.

Using a whiteboard marker, draw a full-scale template of your sheets to verify and adjust angles and dimensions as necessary.

Weld all sides to join the ends and form your polygonal sheets.

Use an angle grinder to smooth excess welding material. This is essential to ensure the mold lies flat against the sheets, preventing damage and preventing plastic from leaking if the surface is uneven.

How to Make a Polygonal Sheet

Calculate the area of your polygon from the drawing to determine the required plastic amount.
