Winter Weather Reminder!

Managing Shipments of Freezable Materials
During winter months, freezable materials, like colloidal silica based binders, should be shipped as early as possible in the week to ensure that they are continuously moving to their destination. While this does not guarantee product will not freeze, it reduces the risk associated with shipping over a weekend where product may sit at a freight facility unprotected from freezing temperatures.

To help you ensure that the product you receive has not been damaged, Ransom & Randolph applies a freeze check indicator, which features a check mark in a green circle. Temperature-sensitive liquid is encased in a clear bubble over the check mark. The fluid will turn opaque and the check mark is no longer visible once it has been exposed to subfreezing temperatures.

Freeze Check Indicator

If this occurs, immediately:

  1. Make a notation on your carrier delivery receipt prior to the carrier leaving your facility:
    “POSSIBLE CONCEALED DAMAGE – PRODUCT HAS BEEN EXPOSED TO FREEZING TEMPERATURES”
  2. Contact R&R customer service to have a freeze test kit sent to you. The material will need to be tested as soon as possible. Instructions will be inside the kit as how to proceed.

ICI Annual Conference & Expo

ICI Booth SalesICI BoothThe Investment Casting Institute recently hosted their 61st Annual Technical Conference & Equipment Expo in Covington, KY.

Ransom & Randolph was pleased to attend and introduce new products at this year's expo, including MXC Excel concentrate and MXC Boost X2 concentrate.


In the spirit of the Matrixcote® system, R&R developed MXC Excel concentrates and MXC Boost concentrates after working closely with foundries to improve dewax performance and casting results. The MATRIXCOTE system can be used in a variety of combinations, each tested to provide best-in-class performance.

During the Conference, R&R's Applications Manager, Conrad Holek, presented the Technical Paper, Evaluating Spalling Factors through Measuring Intercoat Adhesion. The scope of this paper focuses on the development of a testing method and equipment to measure the force of the weakest point at which a ceramic shell sample will delaminate.

R&R’s sales and technical teams work closely with customers to identify casting goals and customize systems to achieve those goals.
