18 of 74
Glue- PVA
White water based, not waterproof, strong. Soaks into the surface and hardens once water is absorbed
19 of 74
Glue- synthetic resin
waterproof, mixed with water to make creamy consistency, chemical hardening occurs and it becomes hard and brittle
20 of 74
Glue- hot melt glue
used in glue guns for quick modelling, difficult to control so not used for final product
21 of 74
Glue- epoxy resin
versatile, expensive, glues most clean dry materials together. Mix equal amounts of resin and hardener and it sets hard
22 of 74
Glue- contact adhesive
used to glue plastic laminates onto chipboard. produces dangerous solvent fumes so needs good ventilation
23 of 74
Glue- latex adhesive
rubber solution, cheap, very safe. Used to glue felt into a box. Has a non dangerous fishy smell
24 of 74
Why is polish added to wood?
To protect from moisture, enhance the colour of the grain and make it easier to clean
25 of 74
Production- one- off production
A product is made one at a time. This is expensive
26 of 74
Production- batch production
a series of identical products are made together using the same equipment
27 of 74
Mass Production
different components are made at different stages by different people. This is cheaper. For example a car
28 of 74
Continuous production
The product is continuously produced over a period of hours, days or years and is cheap. For example milk
29 of 74
Just-in-time production
when components arrive at the factory when they are needed. This uses less storage space so saves on warehouses
30 of 74
Quality assurance
checks production systems before and after manufacture
31 of 74
Quality control
guarantees the accuracy of a product by using jigs and moulds. Also testing the product once it has been made
32 of 74
What is COSHH?
Control of substances harmful to health
