COMPOSITE TOOLING AND EQUIPMENT MAINTENANCE

Release agent are coated on the surface of the mold, so that the parts easy to be separated from the mold

• TRUE

• FALSE

Open mould processes are suitable for both simple and highly complex parts.

• TRUE

• FALSE

The different between open mould and closed mould is:

• open mold is close to the atmosphere at the top

• closed mould is the two mold parts are joined, clamped by vacuum, and resin is injected into the mold cavity assisted by vacuum.

• open mould has a cavity that is entirely enclosed by the mold,

• open mould have fewer emissions

what is resin transferred moulding?

• resin is injected under pressure into a mold cavity.

• The mold set is mounted in a hydraulic or mechanical molding press and the molds are heated from 250° to 400° F

• a continuous process for the manufacture of products having a constant cross section, such as rod stock, structural shapes and golf club shafts

Filament winding is a fabrication technique mainly used for manufacturing open (cylinders) or closed end structures (pressure vessels or tanks). Choose the correct statement about filament winding.

• Fiberglass direct rovings are immersed in a wax bath where they are coated with resin system

• The impregnated tows are then literally wound around a mandrel (mold core) in a controlled pattern to form the shape of the part.

• the resin is then cured, typically using heat.

• The mould core cannot be removed and must remain as an integral part of the part.

Machine or equipment that breaks down frequently could be failing due to a variety of reasons such as:

• proper installed or setup

• Poorly designed or built

• Poor maintenance practices

• perform preventative maintenance regularly.

There are several techniques that can be done for maintenance purpose:

• Any machinery undergoing maintenance must be isolated and locked off if there is a risk of the item being restarted before maintenance is complete

• A risk assessment should NOT be carried out and workers should be involved in this process.

• There is no requirement for suitable tools and equipment, including personal protective equipment.

• No need skills to do the maintenance

Every maintenance must has a correct method or suitable technique to avoid any damages of equipment and tools. Types of Maintenance:

 

• Corrective maintenance

• Breakdown maintenance

• Predictive maintenance

• Preventive maintenance

• Flexibility in staffing, expertise, and work quality

• Roles within a client and contractor organisation may be duplicated, increasing overall cost.

• Most industries are driven by cost management, which is a primary reason for outsourcing.

What should be done for efficient workplace housekeeping?

• improper Storing materials

• Control dust
