Shielding Block Production


Block Casting Styrofoam
We offer quality oncology grade Styrofoam blocks in any sizes to meet all your needs. Standard sizes are listed in the left chart on this page but any custom blocks are also available upon requests. All our Styrofoam blocks are very carefully cut to provide a flat surface and smooth edge, facilitating messy clamps and prevents leakage. Styrofoam Belly boards are also available for custom sizes and cut-outs.   

* Custom blocks are also available upon requests

Refrigerating System

Block Casting Refrigerating System
# BCR-550    for 110V    # BCR-550 @220    for 220V
This casting system features a 3 Gal. of alloy pot mounted on a refrigerated cold plate. The aluminum cooling plate is precision-surfaced and measures 36"W x 24"D x 3/4"T to accommodate 5 ea. of 10” x10” Styrofoam Blocks simultaneously which makes them cost-effective and productivity-efficient systems for the production of shielding blocks.
* Upper Part for Melting: about 15 Kgs    Pot Dim. : shown below
* Lower Part for Casting: about 89 Kgs    Base Dim.: W45cm x D42cm x H101cm

Melting Pot

Melting Pot (3.0 gallon with digital readout)
# BCP-550    for 110V    # BCP-550 @220    for 220V
This pot is accurate for setting temperate ( ±1 ℃) and comes with a stainless steel cover. It is ideal for re-melting electron blocks due to large inside width (30 cm). For safety, ELCB (Earth Leakage Circuit Breaker) are built in the back recess.
Internal dimensions of tank: W 30cm x D 20cm x H 20cm
External dimensions of tank: W 35cm x D 25cm x H 25cm
External dimensions of entire pot: W 45cm x D 25cm x H 42cm
Weight: about 15 Kgs
