Nylatron: Nylon Castings: Custom Casting Permits Intricate Part Detail And Thick Cross Sections

1. CUSTOM CASTING PERMITS INTRICATE PART DETAIL AND THICK CROSS SECTIONS
Application:
A major conveyor manufacturer designed a special carrier for automatic material handling and delivery. Annual part volume req uirement: 1,000 pieces.
Original Production Method: Fabricated carrier from high tensile aluminum alloy.
Problem:
The high strength-to-weight ratio required an expensive
al uminum alloy that made the components very costly. Once prototypes were fabricated, the system was determined to be unacceptably noisy. Parts could not be injection molded due to thick wall sections.
Custom Casting Solution:
Polymer, working with the conveyor manufacturer, developed a
new material and designed a special tool to cast the 3 intricate pmts that now require machining only on critical dimensions.
BENEFITS OF CUSTOM CASTING THIS COMPONENT
• Part cost reduced to 1/5 of original design by utilizing lower cost Nylatron ® nylon
material and custom casting to reduce machining
• Nylatron nylon dampened vibration and reduced noise to within OSHA standards
• Less power was required to run the lighter weight system
The result was an assembly that cost 1/5 the original design and drastically
reduced opera ting noise level. It also was half the weight, lowering conveyor system power requirements.

2. Nylon is one of the most widely used engineering thermoplastics because of its exceptional offering of mechanical performance, low coefficient of friction and cost efficiency.
Nylon, Extruded, Type 6/6, Unfilled
Nylon 6/6 has a much higher melting point, better mechanical properties due to greater hardness, and lower water absorption than cast nylon.
Nylon, Extruded, Type 6/6, MoS2 and Kevlar® Fiber Filled This grade has become a standard thermoplastic wear part material for many industries, most commonly used for large parts (gears, sheaves, sprockets and custom parts) with improved load bearing capability allowing for longer part life, decreased mating component wear, and less down time.
Nylon, Extruded, Type 6/6, Solid Lubricant Filled
This material is a type 6/6 extruded nylon compound with special additives offering superior bearing properties.
Nylon, Extruded, Type 6/6, Glass Filled Nylon 6/6 is very easy to modify with fillers, fibers, internal lubricants, and impact modifiers. Glass Filled nylon Variants of this nylon exhibit increased structural and impact strength, and rigidity.
Nylon, Extruded, Type 6/6, Kevlar® Fiber Filled
Nylon filled with Kevlar® aramid fibers result in a material that is strong, tough, and resists wear – up to 20 times greater than nylon alone. This thermoplastic composite outperforms metals, glass, or other reinforced plastics.
Nylon, Cast, Type 6, Unfilled The casting process of cast nylon 6 results in less stress than the extrusion process, thus providing better dimensional stability. Nylon 6 exhibits all the properties which generally make nylon a superior engineering material: high strength, low friction and wear resistance.
Nylon, Cast, Type 6, MoS2 Filled
Molybdenum disulphide-filled (MOS2 filled) and oil-filled nylons have enhanced wear properties and filled variants which increase structural and impact strength and rigidity or lubricity.

3. Nylon, Cast, Type 6, Oil Filled This is a cast nylon with built-in oil lubrication. During the manufacturing process, oil lubrication is completely and evenly dispersed throughout the cast nylon, making it an integral part of the material’s structure that cannot spin out, dry out, or drain out, even under the harshest working conditions.
Nylon, Cast, Type 6, Glass Filled
The addition of glass fibers to nylon in various amounts (10%, 20%, 30% and 40%) increases tensile strength, stiffness, compressive strength, and a lower thermal expansion coefficient over conventional unfilled grades.
Nylon 101 PA66 Of all the unmodified nylons, Nylon 101 is the strongest, most rigid and has one of the highest melting points. It is commonly specified for screw machined electrical insulators and food contact parts.
Metal Detectable Nylon
This polyamide 6 grade, containing a metal detectable additive, has been specifically tailored for use in the food processing and packaging industries where it can easily be traced by the conventional metal detection systems installed to detect contamination of the foodstuffs.
Nylon, Extruded, Type 6/12 The addition of glass fibers to nylon in various amounts (10%, 20%, 30% and 40%) increases tensile strength, stiffness, compressive strength, and a lower thermal expansion coefficient over conventional unfilled grades.
Nylon HS Blue
Nylon HS Blue is heat stabilized cast nylon 6, which is easily distinguished by its distinctive blue color. It is manufactured with additives in the form of high temperature resistant colorants, U.V. stabilizers, and heat stabilizers which allow HS Blue to retain its properties in applications operating at elevated temperatures. This reduces stress distortion that can be caused by machining.
Nylon Threaded Rod This threaded rod is lightweight, inert, non-toxic, tasteless, weather resistant, non-aging, non-sparking, mechanically stable, non- flammable and will not support combustion. Maximum temperature is 200 degrees F. Excellent for use in chemical industry, oil refineries, food processing, and marine applications.
