The Verdict Is In… CWM and Stenograph Win the IMA Award for Die Cast Design!

Published by:

Stenograph Luminex parts were cast by Chicago White Metal. Screen frame and Keyboard Chassis

The Screen Frame casting (left) and the Keyboard Chassis casting (right) are the 2016 Winners for the IMA Award for Design Excellence.  

IMA Die Casting Excellence Award for Magnesium Part

The IMA Award makes its way home from Italy to CWM!

The verdict is in – Chicago White Metal joined forces with Stenograph to not only meet the requirements for producing the high-end stenotype machine parts, but also to win the “case” for Commercial Castings – Excellence in Design from the International Magnesium Association (IMA).

The International Magnesium Association (IMA) was founded in 1943 with a mission in mind – “promote the use of the metal magnesium in material selection and encourage innovative applications of the versatile metal.”

Stenograph produces high-end, portable stenotype machines for court reporters with exceptional quality.  The Stenograph Luminex is more than 1 lb. lighter than the previous model, 33% thinner, and stands at a mere 2.5″ tall.

Walter & Carolyn Treiber accept IMA Award for Die Cast Design.

This Award of Excellence is an annual award that is given to the company demonstrating an outstanding example of the use of magnesium.  The magnesium screen frame serves as an ideal metal replacement for plastic, creating a high-end “feel” and look to the end product.  The keyboard chassis replaced aluminum with magnesium for decreased mass, allowing the final product to offer maximum portability.

Walter Treiber explains at the IMA’s World Conference in Italy why magnesium was ultimately chosen for the die cast design of this particular casting.

Magnesium’s ability to be die cast with an excellent surface finish allows the screen frame part to readily accept a highly cosmetic appearance, giving a sleek, reflective surface finish to the screen frame.  A court reporter is expected to type the official transcripts of court hearings several times a day with amazing efficiency, so the decision to cast the keyboard chassis in magnesium reduced the overall end product mass, which increased portability from one courtroom to the next.”

Congratulations to Chicago White Metal and Stenograph for the success and excellence in die casting!

Die Casting 101: Hot Chamber vs. Cold Chamber

Published by:

hot chamber and cold chamber die cast parts groupHigh pressure die casting (HPDC) is a process where molten metal is injected under very high pressure into premium steel molds (dies) in order to manufacture high precision die cast products.  The die is designed to cast engineered shapes and complex features with great accuracy and consistent replication.

There are two types of HPDC which Chicago White Metal provides: hot chamber die casting and cold chamber die casting.  Although there are several similarities between the two types, they exist separately for different purposes.

Hot Chamber Die Casting

This is the hot chamber die casting process when the plunger is in the "up" position. Hot chamber die casting is a type of die casting that uses alloys with low melting temperatures (i.e. Zinc, some Magnesium alloys).  Using alloys with high melting temperatures would result in
damage to the gooseneck, nozzle and other components.

In a hot chamber die casting machine, the fixed die half is called a cover die, which is mounted to a stationary platen (large plate to which each die half is mounted) and aligns with the nozzle of the gooseneck.  The movable die half is the ejector die and is mounted to a movable platen, which slides along tie bars.

This is an illustration of the hot chamber process when the plunger is in the down position. The metal is contained in an open holding pot, which is placed in the furnace and melted to the needed temperature.  When the plunger is in the “up” position, the molten metal flows into the shot chamber.  As the plunger moves down, it forces the molten metal through a gooseneck and into the die at injection pressures ranging from 1,000 – 5,000 psi.

The machine pushes the moving platen towards the cover die and holds it closed with great pressure until the molten metal is injected.  The plunger remains in the “down” position to hold the pressure while the casting “cools off.”  After solidification, the plunger is retracted and the cast part is either ejected, manually removed from the machine or pushed off the cover die.  This ejection system, which includes an ejector die and ejector pins, allows the casting to be pushed out while releasing the die halves.

Cold Chamber Die Casting

This is an illustration of the cold chamber process. The ladle is pouring the molten metal alloy into the shot chamber. Cold chamber die casting is a type of die casting that is used for alloys with high melting temperatures (i.e. Aluminum and some Magnesium alloys).

As a contrast from hot chamber die casting (pumping molten metal into the machine), molten metal is ladled from the furnace into the shot chamber through a pouring hole.  While the general function of the cold chamber machine is similar to hot chamber, cold chamber works with a horizontal orientation and does not have a gooseneck.  The ram is pushing the molten metal from the shot chamber into the die cavity to create the die cast part. Instead, the plunger forces metal through the shot chamber into the die at pressures ranging from 2,000 and 20,000 psi.  The plunger holds the pressure and retracts after solidification.  The clamping unit and mounting of dies is set up the same as hot chamber, however the cover die for a cold chamber machine does not have a gooseneck or nozzle, and therefore aligns directly from the shot chamber.

The Village of Bensenville and CWM Strengthen Ties with a Facility Tour

Published by:

VillageOfBensenville-Evan-Summers-Mike-Martella-Eric-Treiber-Mayor-Frank-Soto-CWM-Die-Casting-Tour Chicago White Metal further strengthens its ties with Village of Bensenville by offering an exclusive tour of the CWM facilities.  The relationship between Bensenville and CWM has existed since the 1970’s, when the company moved from its Chicago location and built the Bensenville plant.  About 1 1/2 years ago, CWM was featured on the Village of Bensenville local TV show, “Made In Bensenville,” in which Mayor Frank Soto and Eric Treiber discussed the manufacturing industry, the history of the company, the current state of die casting, corporate culture, and other issues.

Mayor Soto was accompanied by new Village Manager Evan Summers and Marketing & Business Development Administrator Mike Martella.
