Block Casting

COPYCAST^™ is not only used as a casting duplication system, it is also used as a block casting system for machining patterns, models, and molds.  COPYCAST^™ machines quickly, can be patched, changed and does not require the time, cost and waste associated with gluing-up boards.

CopyCast has been formulated to thicken like yogurt when standing still.

This thickening effect keeps the system from settling.

To use CopyCast, it must be vigorously mixed or shaken by hand or machine. The more vigorously you mix, the thinner it becomes. By putting energy into the system, CopyCast becomes a thin,
ready to use liquid. When you don’t use CopyCast and let it stand, it becomes a liquid gel until
you reactivate it. It works just like yogurt!

Mixing directions for CopyCast in steel cans

Option 1:  Use a paint shaker

1.       Shake for 1-3 minutes or until thin.

2.       Remove the lids with a flat tipped large screwdriver.

3.       Use CopyCast @ 1:1 by weight or volume.

NOTE:  Paint shaker mixing can make the compounds thinner.

Option 2:  Use a power mixer

1.       Remove the lids with a flat tipped large screwdriver.

2.       Mix for 2-4 minutes, or until thin.

3.       Use CopyCast @ 1:1 by weight or volume.

NOTE:  Power mixing can make the compounds thinner.

Option 3:  Use a spatula

1.       Remove the lids with a flat tipped large screwdriver.

2.       Mix by hand with a spatula until thin.

3.       Use CopyCast @ 1:1 by weight or volume.

NOTE:  Power mixing can make the compounds thinner.

SURFACE PREPARATION TO PREVENT ADHESION:

To prevent adhesion to the mold, use a GREASE IT release agent. The following are recommended; GREASE-IT IV, GREASE-IT V, GREASE-IT WAX P, or GREASE-IT WAX L. Use GREASE-IT FDG when a Food & Drug grade release is required. For best results, apply 3 - 4 thin coats, drying between coats. Porous surfaces (wood, plaster, etc.) must be sealed thoroughly before release is applied.

Use multiple coats of a good coating, such as: a high grade lacquer or urethane lacquer.

 SURFACE PREPARATION FOR ADHESION:

For applications where adhesion is desired, the surface must be cleaned, abraded and dried. Sandblasting and mechanical roughing are the preferred ways of abrading surfaces to be bonded. Make sure all surfaces are clean, dry and free from moisture.

SHRINKAGE:

Shrinkage or dimensional variation is largely influenced by 5 factors:

  1.  Mass (total volume and thickness)

  2.  The temperature of the material

  3.  Maximum temperature reached during the exotherm (reaction).               

       The faster the material, the higher the exotherm, the greater the shrinkage.

  4.  The temperature of the mold

  5.  The stability of the mold

Geometry, part thickness, and total volume vary in each design, therefore, the customer is responsible to test and determine the shrinkage factor to be used. The values in the brochures are for comparative reference only, using ASTM testing procedures.

CASTING:

Pour in a thin unbroken stream into the lowest point in the cavity or mold. This will help break up some of the air entrapped during mixing.         

 AIR RELEASE:

Use HAPCO’S ANTI-AIR to aid in air release (see Technical Bulletin). In some products, ANTI-AIR can cause a slight haze to cloudiness. This has no effect on properties.         

MIXING: 

IMPORTANT:  Before each use, shake individual components, Part A and Part B, thoroughly before proportioning out the required amount. Components may separate and should be mixed before each use. Mix, only when ready to use, by adding the curing agent to the resin portion and blending together thoroughly. Be sure to scrape and stir in all material sticking to the sides and bottom of the mixing container.  Do not use paper containers or wooden mixing sticks. They may contain moisture. For best results, use plastic or coated containers, and metal or plastic sticks.

MACHINE MIXING AND DISPENSING:

Use HAPCO’S RAPIDSHOT Dispensing Equipment for fast, reliable, and efficient dispensing.

CLEAN UP:

Cured polymers are most difficult to remove. It is best to clean tools and equipment immediately after use.

Use Hapco’s A-TAK for the best results.

STORAGE:

Polymer systems have a minimum shelf life of six months when unopened. Both components should be stored in a room temperature dry place. When not in use, containers should be kept tightly closed.   

RESEALING:

Many polymers are moisture sensitive, for best results reseal, using one of the following two methods: blanket with nitrogen or use a hair dryer for 30 seconds to cover with dry air.

 PRECAUTIONS:

Skin or eye contact with polymers should be avoided. Clean housekeeping procedures are urged and the use of gloves and/or protective creams suggested. All polymers, as a general practice, should be used in well ventilated areas.  Spot ventilation is most effective. Contaminated clothing should be removed immediately and the skin washed with a waterless skin cleaner then with soap and water. Should accidental eye contact occur, wash thoroughly with water and consult a physician.
