Patternmaking Procedures ---------------------------------------------------------------------------------------------------------------------
DOUBLE MATCH-PLATE PATTERN
IKBNT Foundry Lab 2011AI-1
Step 1: Tools and materials preparation.i) Prepare tools and materials to make a
pattern.ii) Sketch the outline design on the wood
plate.iii) Cut the wood (roughly) following the
outline design.Equipment: Steel ruler, vernier caliper, measuring tape, band saw and pencil.
Step 2: Pattern (product) preparation.i) Carve the wood following the outline
design.ii) Use carving tools set, sand paper, sanding
machine, wood lathe, saw and file to make a pattern.
Step 3: Match-plate pattern preparation.i) Use plywood to fabricate the match-plate.ii) Using wood bond, attach the solid pattern
to the match-plate.iii) Attach the well, runner sprue and riser on
the determined locations accordingly.
Step 4: Finishing.i) Use the putty filler to repair any hole or
rough surface.ii) Use sand paper to finishing.

SPLIT PATTERN
IKBNT Foundry Lab 2011AI-3
Step 1: Tools and materials preparation.i) Prepare tools and materials to make a
pattern.ii) Sketch the outline design on the wood
plate.iii) Cut the wood (roughly) following the
outline design.Equipment: Steel ruler, vernier caliper, measuring tape, band saw and pencil.
Step 2: Pattern (product) preparation.i) Make the shape following the outline
design using jig saw.ii) Use file and sand paper to refine the
surface finish.iii) Split the pattern into 2 using band saw at
the center of the pattern.Equipment: File, jig saw, sand paper and band saw.
Step 3: Pattern dowel and guide holes.i) At one side of the pattern, drill the guide
holes at the determined locations.ii) At the other side, attach the dowel at the
determined locations.
Step 4: Finishing.i) Use the putty filler to repair any hole or
rough surface.ii) Use sand paper to finishing.

Step 1: Wood preparation.i) Select the type of wood available for
patternmaking process in the laboratory or workshop.
Step 2: Tools and materials preparation.i) Prepare tools and materials to make a
pattern.ii) Sketch the outline design on the wood
plate.iii) Cut the wood (roughly) following the
outline design.Equipment: Steel ruler, vernier caliper, measuring tape, band saw and pencil.
Step 3: Match-plate and product pattern preparation.i) Carve the wood following the shape using
carving tools set, files, sand paper and sanding machine.
ii) If the shape is cylindrical, use wood lathe machine.
iii) At the front view of the previously prepared match-plate, attach the product pattern using wood bond.
Step 4: Gating system preparation.i) At the back view of the match-plate attach
the gating systems (well, runner, gate and etc.) at the determined locations.
Step 4: Finishing.i) Use the putty filler to repair any hole or
rough surface.ii) Use sand paper to finishing.
