Lamination of wood

Question 1

What is lamination of wood?

Advantages of laminating wood?

Disadvantages of laminating wood

Answer 1

Wood laminating is the process of forming multiple sheets of veneer, chips or solid timber using moulds, clamps and glue, to produce rigid, lightweight and complex structures.

Price - The wood is made from composite materials which are cheaper than other types of wood.

The wood is more resistant to scratches, moisture, wear and even sunlight due to the coating applied at the end of production.

Laminated wood is not as visually appealing as other woods due to its artificial wood grain.

Laminated wood is very hard to repair.

Question 2

One-off vs Mass Production

Answer 2

One-off production products are very expensive due to the amount of time, skill set and resources used on it.

One-off productions are also very time-consuming

Mass production has a huge initial investment due to the large-scale machines needed to start production.

One machine breaking can halt production causing there to be a delay in finished products and could potentially stop an order being shipped o time.

Many jobs will be lost due to the very automated process.

Question 3

What is rapid prototyping?

Advantages of rapid prototyping

Disadvantages of rapid prototyping

Answer 3

Rapid prototyping is using various different types of manufacturing methods such as CNC machines to create a scale model of your design.

rapid prototyping shows design flaws in your product which will help you save time and money in the long run.

Shows what the product will actually look like real life which could change your ideas.

Not as effective because it doesn’t simulate real production methods for the product causing inaccuracies

Question 4

What is reverse engineering?

What are the advantages reverse engineering?

What are the disadvantages reverse engineering?

Answer 4

This allows companies or people to improve products that are already in the world by changing a few core details.

This saves money by not having to replace the product completely.

An object can never be fully disassembled to its raw materials and design.

This is a very tie consuming which wastes a lot of time and money

Question 13

JIT deffintion , advantages and disadvantages?

Answer 13

JIT production is when the raw materials needed for an order is ordered jit for use.

Money is very efficiently used

Warehouses are not needed for storage

No waste or excess stock

Question 14

Sustainability issues with Car Manufacture

Answer 14

Damage to the environment including animal habitats

Noise pollution

Visual pollution

Atmospheric pollution including acid rain, greenhouse effect global warming

Production in factories

Transport and use of cars

Question 15

Importance of marketing

Answer 15

Promotes your product which increases customer contact and memory

Tv adverts Promote brand image and recognition. This can also target a certain audience

Packaging is a big role due to the amount of information it can provide. e.g Brand logos, information about product and brand and attracting people

Question 16

WHAT ARE MANMADE BOARDS?

Answer 16

Manmade boards are commonly used in the construction industry, for interior fittings and furniture. They are more stable than natural woods and are less likely to warp and twist out of shape.

The three main types are; plywoods (laminated boards), particle boards and fibreboards.

They are all manmade in factories/mills. They are usually composed of natural woods and resin, which binds them together.

Question 17

What are Plywood and the 3 different types?

Answer 17

Plywood is a composite material. Composed of individual plies/veneers of wood. The plies are glued together with synthetic resin.

Softwood ply tends to be used in the construction industry for walls, roofs and floors.
———————————————————————————-Hardwood ply often used for quality laminate flooring, kitchen units and some furniture.
———————————————————————————-
Marine plywood is specially treated so that it is water resistant.
Manmade boards such as plywood can be manufactured so that they are extremely wide. This makes plywood a popular material in the construction industry.

Question 18

What is BLOCKBOARD and its uses?

Answer 18

A type of plywood. Built up with a core of softwood strips bonded together with adhesive and covered with a sheet of plywood on either side.

Used as a building material and for furniture manufacture including fitted kitchens / bedrooms.

A strong and heavy board, unlikely to warp and twist. The plywood faces are normally beech or other natural woods.

Question 19

What is CHIPBOARD and its uses?

Answer 19

This is made up of small chips of wood bonded together with resin and formed into sheets by compression.

It is not as strong as plywood or block board, but it is not expensive. Chipboard is often covered with a plastic laminate or wood veneer and used in cheap furniture.
A particle board. Interior and moisture resistant chipboards are available.

Question 20

What is MEDIUM DENSITY FIBRE BOARD (MDF) and its uses?

Answer 20

A quality board, relatively cheap. Composed of fine wood dust and resin pressed into a board.

Can be worked, shaped and machined easily. Paint can be applied to it, without the need for an undercoat or primer (although finishes better with an MDF primer).

Used widely in the building, shop fitting and furniture trades.

Question 21

What is HARDBOARD and its uses?

Answer 21

Made from wood fibres that have been pulped.
The pulp is put under pressure until the fibres bond to produce a tough board.

Standard hardboard is smooth on one side and rough on the other. It is not as strong as the other boards.

Question 22

What is compression moulding and its process?

Answer 22

Compression moulding is the process of moulding a polymer in an open mould cavity using high pressure and heat.

A two-part mould is created which contains the designed mould.

The lower mould is heated which contains the plastic composite.

The upper mould is forced down maintaining high pressure and heat.

The upper mould moves up and the ejector pin removes the product
