TRANSCRIPT
Development: Production Method
Lesson objectives
• At the end of the lesson, students are able to:
1. Understand the different production methods and how to apply it in development
Steps in development in production method
• Show at least different methods of assembling the different parts
• Choose the method of assembly that best suits your product

• Nails are driven into
the wood in a
parallel manner.
• Dovetail nailing
provides a stronger
joint.

staggered
• Staggered nailing reduces the
risk of splitting the wood grain.

• Screws can be used for joining
different materials.
• Wood is joined using wood
screws; metals and plastics
are joined using machine
screws.
• Joints are strong but
temporarily because they can
be taken apart at a later date.
• Common types of wood screws
are the countersunk head
screw and round head screw.

• Materials can provide strong
joints using nuts and bolts.
• Common types of bolt heads
include hexagonal, square,
cup, countersunk and cheese
head.
16.10 Joining and Assembling Processes
• Nuts and bolts can be fastened using
a spanner.
• Common types of spanner include
adjustable, open-ended and ring.
• Choose a spanner that is a snug fit.

• Rivets are used to join metals and other sheet materials
permanently with strong joints.

• Thin sheet materials can be
joined quickly and permanently
using pop riveting.
• This type of joint is not strong.

• Wood is usually joined using
polyvinyl acetate (PVA) glue
or contact glue.

• A wide range of adhesives, solvents and cements are
available for joining similar or dissimilar materials.
• Adhesives can close gaps between joints.
• Metals are usually bonded using the following adhesives:

• Solvents such as chloroform and liquid poly permanently
join acrylic and polystyrene respectively.
16.10 Joining and Assembling Processes
• They dissolve the
surfaces that are in
contact and fuse
them together.
• Other solvents are
available for joining
other plastics.

• Knock-down fittings enable
materials to be joined and
taken apart without
weakening the joints.
• These are commonly found
in modern self-assembled
furniture.
