Fishing Lure & Metal Parts Making Applications 
 
Spin casting is a simple, cost effective alternative for casting functional prototypes to high volume production runs in pewter, zinc, tin & lead base alloys or thermoset plastics such as Urethane Polymers (Polywood), Epoxy, & Polyester Resins. 
 
For many years now; Spin Casting has been the conventional system for casting lead ballast onto fish hooks for small jig making such as crappie jigs and many others. It is also the primary system for mass producing spinner bait style, wireform, lure heads. 
 
Now that RTV Plastics such Industrial Polymers Inc. Polywood (refered to in the LMM as liquid balsa wood) is available to Lure Makers; Spin Casting systems make it possible to produce thousands of parts per day with high cost effeciency, and relative low cost for initial set up. 
 
With Spin-Cast Systems; Precision Parts Are Manufactured With Major Savings In Time & Labor... 
 
CAST HIGH-STRENGTH ENGINEERED METAL PARTS - Equivalent to those produced by pressure die casting and other fabrication processes. Spin-Casting Systems provide high levels of strength, close tolerances and excellent reproduction of detail. It produces high-quality parts in commercial grade: PLASTICS, ZINC ALLOYS, TIN ALLOYS & LEAD ALLOYS. 
 
Cast Rapid Prototyping & Product Development Parts In Just Hours! IMPROVE DESIGN FLEXIBILITY - Molds can be made and prototypes or development parts cast in as little as three hours. Design changes in size, function, fit or appearance are quickly reproduced without making or wasting a large tooling or machine-time investment. 
 
From Pattern/Model To Production Castings In Less Than One Day. SPIN-CASTING PROVIDES A HIGHLY COST EFFECTIVE ALTERNATIVE TO LIMITED-RUN PRECISION DIE CASTING AND OTHER CASTING OR FABRICATION TECHNIQUES - An entire Spin-Casting system can be set up for less than the cost of one moderately complex die casting mold. Silicone rubber molds can be cycled as many as 50-60 times per hour, for hundreds of cycles. For example: a 20-part/cavity mold can produce 1000-1200 components per hour, thus providing high production run capabilities. 
 
PRECISION CASTING PROCESS - Production Parts Typically Meet Tolerances in the ±.005-.008 Inch per Inch Range. 
 
CAST PRECISION WAX PATTERNS - For use in Lost Wax Investment Casting of Ferrous and Non Ferrous Metal Parts.
