No-Bake CoreMaker™ CM-Series Core Blowers

CM-Series Core Blowers Benefits

The COREMAKER was designed to provide small to mid-sized jobbing foundries a simple, dependable, low cost core blower. The approach Palmer has taken in this product greatly reduces the overall equipment cost for blown cores by eliminating expensive, non-essential controls and gadgets. The COREMAKER comes with a M-Series Swivel Mixer to make cores and sizeable molds. Molds and cores can be produced on the same machine!

A primary consideration in the design of the COREMAKER was productivity. Through time studies, it has been determined that it is more efficient to blow multiple core boxes from the same chamber of sand instead of “batched” mixes for each core.

• High Productivity with Amazing Simplicity 

• Available for air setting or cold box binder systems 

• Works great with wooden dump boxes, shell tooling, cold box tooling. Ideal for low volume work blown core work, for replacing oil sand core making systems, where shell cores require too much setup time for order quantity, and where shell tooling is too expensive. 

• Simple, Rugged Design 

• Does not require intricate venting in the no-bake version. 

• No scrubber required with air setting binders 

• Ideal for small to mid-sized jobbing foundries 

• Blow cores and make molds with the same machine with optional swivel mixer. 

• Dual resin systems available to make no-bake and cold box cores with one machine. 
   

Standard Features

• Super-Duty Clamping Table and Cylinders.
• Fill timer for control of any continuous or batch mixer.
• Warning timer and buzzer for advance notice of work time expiration for air set systems 
• Rigid, long life fabrication and heavy duty components. 
• 120V Operation
• The simplest, most cost effective method to enter the blown core casting market. 
• Spare parts are available from full service industrial supply houses or from Palmer's extensive inventory.
• The Cold Box CoreMaker comes complete with a gas generator & gassing head. Palmer also has a complete line of Scrubbers.
• The No-Bake CoreMaker is not just a core-blower. The mixer rotates 90° to allow mixed sand to discharge outboard of the CoreMaker footprint. This allows for molds and very large cores to be produced – all on one machine!

CM-Series CoreMaker™ with RFID

Palmer Manufacturing & Supply, Inc., has introduced the addition of RFID (Radio-Frequency Identification Tags) to their standard line of CM-Series CoreMakers. The Palmer CoreMaker provides foundries with an economical means for the blowing of No-Bake and Cold Box cores.

Both versions of the Palmer CM-Series CoreMakers™ are available with RFID tagging that saves the settings – program it once & forget it.

Components Overview

Primary Fabrication - The CoreMaker is designed around a backbone of heavy wall steel tubing. Absolute machine rigidity was designed in to the COREMAKER. With full clamping pressure, the machine will not flex. The blowing area is completely enclosed to minimize blown sand and safety issues generally associated in blown core areas.

Blow Chamber - The heart of the COREMAKER is its blow chamber. Specially designed for use with air setting binders, the blow chamber's unique geometry prevents sand and resin buildup within. Super heavy construction ensures long life. Unit requires very little cleaning.

Clamping Table - The COREMAKER's clamping table is a heavy-duty, die set typically used for stamping operations. The unit is thoroughly over designed and features 1 3/4" thick steel plates. Two 6" bore cylinders provide for both the motion of the table and the holding pressure needed for blowing. Note that a cleanout tube is located integrally into the clamping table for easy cleaning at the end of a blow cycle (pictured above). Unit purges into a 5 gallon pail located below the clamping table.

Pneumatic System - The highly effective CM-Series features a simple to operate and easy to maintain pneumatic system. Basic, off-the-shelf solenoids control the entire system. The unit includes a surge tank to reduce demands on the plant air system and ensure consistently dense cores.

Control System - The COREMAKER is fitted with a high quality electrical control system featuring standard OEM components and complete control integration. A smart relay is used to control all timing functions. Timer settings include mixer run timer, resin system work timer, and warning buzzer timer. The cold box version features a PLC upgrade to control all system operating times.
