Decoring Hammer

A cost-effective pneumatic core removal tool. Decoring work for cast aluminum, cast steel, and other castings where internal sand core removal is difficult or sand core remains

Decoring hammer is a specialized tool used in foundries and metalworking industries to knock out the core from castings. Cores are used to create hollow sections of a casting, which are often difficult to remove after the casting is cooled and solidified. Decoring hammer is a powerful tool that delivers high-impact blows to the casting to loosen and remove the core.

KCE 70 plus Decoring Hammer

In the Chinese market, KCEN70plus has won more trust due to its quality and high efficiency of decoring in casting, and of course, there are more orders.

KCEN70plus series high-frequency air flushing decoring hammer is mainly used for core removal of cast aluminum, cast steel, and other castings that are difficult to remove internal sand cores, or have sand core residues, such as automobile engine cylinder blocks and cylinder heads, automobile turbochargers Decoring of steel castings, heat exchangers and other castings.

It has the advantages of high frequency, high productivity, good reliability, long service life, and low maintenance cost. And fully compatible with Italy O* **70, 70-, 70-, France G2638. ***2634 decoring hammer replacement, and provide the same warranty.

At the same time, it provides Italy O70, 70-, 70-, France G**2638. ***2634 decoring hammer maintenance service, spare parts supply service, provide the same quality assurance, and the cost performance is also higher.

Three Featured Products of KCE 70plus Decoring Hammer

KCEN70plus: special exhaust system, shock frequency, and shock stability are suitable for the casting decoring of general cast aluminum, cast iron, and cast steel;
KCEN70plus-BL: The shock force is more stable, and suitable for casting decoring of cast aluminum, cast iron, and cast steel parts with complex internal structures and difficult sand cleaning;
KCEN70plus-BR: The shock frequency is higher, the shock force is smaller, and the air pressure is lower, so the air consumption is smaller at the same decoring hammer frequency, especially suitable for the new generation of small and precise (thin walls and cavities) ) castings and castings produced using inorganic sand cores;

Notes: The three decoring hammers can be equipped with an air cleaning device to prevent sand from accumulating on the hammer end and entering the inside of the hammer, especially suitable for occasions with high-reliability requirements; (such as hammering stations that require rotating functions).

• – The service life depends on the working environment conditions, such as the temperature of the struck casting.
/ – Decoring Hammer needs to be replaced after 1500 hours of hammering time, but if the distance between the hammer head and the casting (that is, the striking distance) is not within the specified distance, then such parts need to be replaced after 1000 hours of hammering time.
* – Prevention and maintenance of Decoring Hammers (after 500 hours of hammering or slightly longer) will require repair or replacement of these parts.
# – Such parts are recommended to be replaced every time maintenance is performed.
♦ – It is recommended to be replaced by the original engineer.

Warnings

Decoring hammers must be lubricated regularly with air tool lubricant. Mobil Amer 525 ISO VG 46 oil is recommended. Each decoring hammer must have an independent lubrication system (a drop of oil is lubricated every 3-4 seconds, and a vibration cycle is 20-30 seconds) o
If the decoring hammer is not used for a long time, the inside of the air hammer must be cleaned with a degreasing agent.
The decoring hammer must be inspected and cleaned every 250 hours of actual work (referring to the cumulative hammering time), and a degreasing agent can be injected into the air inlet.
Never use a decoring hammer without a hammer head.
Do not use a decoring hammer without a casting to strike.
In order to ensure that all decoring hammers work normally, all pneumatic hammers are connected with pipelines of the same length.
