1. How do you prep a Thermoplastic material for compression molding? a. Thermoplastic resins may be loaded into the mold either in the form of pellets or sheet‚ or the mold may be loaded from a plasticating extruder. Thermoplastic materials are heated above their melting points‚ formed and cooled. For both thermosets and thermoplastics‚ the better the feed material is distributed over the mold surface‚ the less flow orientation occurs during 2. What are the advantages‚ Strengths

MATERIAL REQUIREMENTS PLANNING (MRP) The material requirements planning (MRP) system provides the user with information about timing (when to order) and quantity (how much to order)‚ generates new orders‚ and reschedules existing orders as necessary to meet the changing requirements of customers and manufacturing. The system is driven by change and constantly recalculates material requirements based on actual or forecasted orders. It makes adjustments to deal with possible problems prior to their

Engineering Materials Week 3 5.1 Briefly explain the difference between self-diffusion and interdiffusion. Self-diffusion refers to movement of atoms within a pure material; interdiffusion refers to the movement of one or more kind of atoms in a heterogeneous system. 5.7 A sheet of steel 2.5mm thick has nitrogen atmospheres on both sides at 900C and is permitted to achieve a steady-state diffusion condition. The diffusion coefficient of nitrogen in steel at 900 C is 1.2 10^-10 m^2/s‚ and the diffusion
