Industrial Mold Making
Our molding products have a wide variety of uses and applications.
Mold safety pads for work boats, industrial and off shore oil industry, helicopter landing pads or playgrounds. Mold 3-dimensial objects without losing details or replace metal injections molds with lower coat urethane molds. Whatever your challenge we have the molding materials offering resistance to oil and grease, drilling fluids, oil crude products, sea water, impact, the elements and UV degradation.
This is a high density, impact resistant, flexible, molding or casting resin product. TrueCast is our most versatile line of compounds: absorbs vibrations, resistant to specific elements and chemicals. Great for rubber seals, bumpers, and rollers.
Insensitive to typical environmental moisture, low viscosity, high strength and low durometer, low residual surface tack, tough, high tear strength, good oil and grease resistance, good flow into detail, dimensional stable, hardness range from Shore 00A to 85 Shore A. Truecast will pour directly into prepared molds.
Also available in a spray series for stand-alone molds and for fine art and natural texture reproduction. The spray versions must be applied with plural component spray systems.
A two component urethane flexible elastomer is specifically formulated as a brush on or trowel on molding compound for any 3 dimensional objects or vertical or overhead surfaces. When mixed becomes a butter-able gel which will not run or sag. This is used as a bonding adhesive for wood, fiberglass, flexible foams, and masonry components. Insta-Gel features tough, high tear resistance, grease and oil resistance, long mold storage life, insensitive to inhibition. Used to fill in surface gaps and bond other urethane pieces together. Contains on VOC’s and will not damage or melt metal paint, plastic or foam surfaces. Hardness range from 25 Shore A to 70 Shore A.
Primary uses include:
- Casting of concrete and plaster parts
- Mold liners for casting of concrete and plaster parts
- Molding wax for bronze sculpturing
Flexible Gel Molding / Casting Compounds
When fully cured this two component urethane provides for hard durable impact resistant coating, part, or water proof sealant for concrete walls or masonry. This multi use product may be sanded, machined, or painted using conventional methods. It is applied with brush or roller eliminating the need for expensive equipment. This product can be used to create a smooth finish on EPS Foam or when combined with chopped fiberglass forms tough durable shell parts. Also, used as a bond for fiberglass beams or to anchor architectural building components, excellent backing for flexible molds. Various set times and work life available. Hardness range from 70 Shore D to 85 Shore D.
A very unique product line allows you to expand or shrink your three-dimensional molded product without losing details or quality. Hydrospan is water-activated; your molded product may be expanded to 161% or reduced 55 to 85% just by soaking in water.
Both products are easy to work with and achieve uniform results when directions are followed. Almost any type of mold is compatible with Hydrospan when properly prepared.
This line has been used by architects, artist, prototype makers, or anyone wanting to change the size of their original product, without losing dimensional integrity.
The TrueCast rubber mold making products combine high strength and durability with easy to use mixing at room temperature. Our urethane molding rubbers provide the highest tensile and tear strength in the industry. TrueCast is available in 11 different Shore A hardness to perfectly suit your mold making needs, with slow setting products included for a longer working life.
The TrueCast products are easy to use, simply mix the A and B components together and pour. Within minutes TrueCast begins to cure into a flexible mold or durable rubber part casting. If you are making high production rubber molds for concrete or cast stone we recommend making your molds from (40 Shore A) to (65 Shore A) hardness rubber.
Rubber molds are an easy low cost method of manufacturing a variety of concrete and plaster display items as well as industrial wheels, bumpers and seals. A rubber mold is constructed by pouring TrueCast around an existing piece of art, a clay master or industrial part, which has been coated with molding release agent. Within hours the TrueCast molding material can be removed from the master. The finished mold can be filled with a variety of casting materials to make hard or flexible parts. We offer 11 different hardness of molding compounds ranging from Shore 0 A to Shore 90 A. Our softer molding compounds are used to create molds of irregular shaped objects with deep undercuts. Harder TrueCast molding products are used for casting more abrasive concrete or masonry products as well as durable rubber parts.
The TrueCast molding rubbers can also used as coatings over flexible foams and for casting solid rubber parts like bumpers, gaskets, seals or rubber wall displays
Molding gels are urethanes which become very thick after the part A and B components are mixed together. Having a urethane product which is very high in viscosity (a paste consistency) allows the product to be applied very thick on a surface without sagging or running down. This is very helpful when you are making a brush on rubber mold skin from a large 3 dimensional master model. A brush on paste consistency is also helpful if you want to brush into an open faced mold to make a large flexible rubber skin for animatronics applications. If you would like to make a rigid plastic shell instead of a flexible rubber skin we manufacture UraGel 770 which cures to become a hard surface. UraGel 770 is sometimes used in open faced rubber molds to make large masks or reproduction suits of ancient amour. UraGel 770 can be brushed into a silicone rubber mold ¼ of an inch thick or more to make high durability rigid plastic parts.
Insta-Gel is a flexible, brush-on product for making rubber molds from objects or wall surfaces which cannot be placed in standard box molds (any 3 dimensional objects or vertical wall surface). After mixing, Insta-Gel® thickens to a creamy spread-able gel which can be brushed onto vertical or overhead surfaces without sagging, or running. Within 24-hours Insta-Gel® cures to a tough rubber mold. Before applying Insta-Gel®, surfaces should be coated with silicone or wax mold release and must be free of moisture to prevent unwanted bonding or surface bubbling. Mold releasing agents must be used to insure easy removal of Insta-Gel® rubber mold from the master.
UraGel 770 is a rigid (75 shore D) brush-on mother mold making material or low odor fiberglass replacement product. UraGel 770 is also used for manufacturing in-mold hard parts, reproduction ancient amour and decorative masks. Use this product any time you need to make hard durable parts from a large open faced mold.
UraGel 770™ is formulated for casting hard mother back-up molds or hard plastic parts. It can be brushed into rubber molds 1/2-inch thick in a single application. When fully cured UraGel 770™ forms a rigid “fiberglass like” polymer which is easily sanded or machined and painted to final form. UraGel 770™ is recommended as a rigid Mother mold back up for flexible Insta-Gel molds. Polyester fabrics and chopped fibers can be used with these materials to enhance strength and durability. UraGel 770’s thick gel consistency makes it easier to work with than fiberglass, no cloth lay-up required. Very thick sections can be created in a single product application, no fumes or odor.
Insta-Gel Spray is formulated for making large rubber molds where high volume production is required. This product cannot be hand mixed, it must be spray applied with special mixing and spraying equipment. The required equipment simultaneously mixes part A and B components together and sprays the product. Insta-Gel Spray molding gels cure more rapidly than our brush-on application rubbers. We recommend 2 types of spraying equipment for Insta-Gel Spray application; the first type is a small hand held dual cartridge spray gun the second is a much larger electric gear driven 2 component plural spray machine. The cost of the cartridge type spray gun ranges from $700.00 to $1500.00 USD. The larger electric spraying equipment ranges in price between $5000.00 to $12,000.00 USD. Both types of spraying equipment can be used with Insta-Gel Spray. The hand held cartridge sprayer may be purchased directly from Industrial Polymers Corporation or other suppliers.
A disadvantage of using the hand held cartridge spray gun is the added cost of the disposable plastic cartridges which only hold 1.5 liters of product and cannot be reused. The cost of the disposable plastic cartridges and mixer tips is approximately $8.25 per cartridge set and it takes approximately 4 complete cartridge sets to spray only one gallon of Insta-Gel Spray rubber. The cost of disposable plastic cartridges adds $33.00 per gallon to the cost of spraying your rubber. If you plan to use large amounts of spray on mold making rubber the more expensive electric spraying equipment may be a good investment over the long run and reduces landfill waste. The electric spraying equipment should be purchased directly from an equipment manufacture/supplier who can offer long term maintenance, technical support and training. We routinely direct customers to Spray-Quip Incorporated at 800-500-9109 www.sprayquip.com or Michael Engineering at 989-772-4073 www.michaelengineering.com for price quotes and help in selecting the spraying equipment which best serves your needs.
