Hot Melt Coating Technology Part 1 technology Most importantly the use of solid adhesive eliminates the need for drying units leading to increased production rates HOT MELT PROCESS Depending on the sophistication of the chemical development group of a specific manufacturer the adhesive may either be purchased or mixed on-site If the adhesive is mixed on-site the components The casting process starts by heating a metal alloy in a crucible until it melts When a metal is heated above its freezing point it becomes liquid This is also known as its melting point The melting point of metal depends upon the type of metal or alloy being used For instance our zinc alloys melt around 900 degrees F whereas some of the bronze alloys we pour melt above 2000 degrees F

PPAP

Introduction to Production Part Approval Process (PPAP) Production Part Approval Process (PPAP) is a valuable tool for establishing confidence in component suppliers and their production processes In today's competitive manufacturing environment controlling cost and maintaining a high level of quality have become vital to a company's success

In this work a multifunctional polymer composite is made using melt-blowing technology from polypropylene (88 wt %) and poly (ethylene terephthalate) (12 wt %) with the addition of functional modifiers that is 3 g of a superabsorbent polymer and 5 g of a biocidal agent (Biohaloysite) The use of modifiers is aimed at obtaining adequate comfort when using the target respiratory protection

As the melt blowing process has allowed the production of microfibers as small as one micron average diameter in a commercial process there has been continuing effort to push the technology to further reduce fiber diameter Recent efforts to design and develop modular dies with smaller holes and larger number of holes allow the production of submicron fibers in a cost effective way One of

Recent advances in die technology have boosted the productivity of cast film production lines Special reference can be made to the so-called internal deckles Inserted on both ends of the die the deckles allow changes to the film width and the consequent reduction of trim They can be fixed or adjustable and their length can exceed 20 inches

The production and surface modification of cellulose nanocrystals (CNC) from Agave tequilana Weber waste (ATW) and their effect on the melt rheology of PLA were investigated For that CNC were obtained from ATW residues by acid hydrolysis and grafted with 2-ethyl hexyl acrylate (2-EHA) to promote compatibility with nonpolar polymers such as PLA

Polymer Extrusion Introduction Extrusion is widely used in various industries In this experiment we investigate plastic extrusion by the screw extruder shown in Fig 1 Such extruders are most common in plastic industry Figure 1 Extruder What Happens in an Extruder? The screw in the extruder rotates and develops sufficient pressure to force material to go through a die and produce
