Md-5008 High Sensitivity Underground Metal Detector for Gold, Silver, Copper

Md-5008 High Sensitivity Underground Metal Detector for gold , silver ,copper 

Introduction:
MD-5008 metal detectors, 3-3.5m depth of detection, adopt advanced technique and attach high quality components which have features of ground balance, good discrimination ability, wide detection range, accurate orientation, strong resolution and easy operation


Application:
The metal detectors are mainly used to detect and identify underground metals. Besides military using, they are widely used in:
(1) Security inspection, public security organs' ransack:
(2) Scan metal foreign matter in raw, fuel and foods;
(3) Scan metal articles in mail or luggage;
(4) Detect underground pipelines, cables;
(5) Archeology, mineral exploration, find underground metal articles.

Component:
(1) Attach external battery box and bag
(2) Attach big and small search coils


Specification:
(1) Emission Frequency: 6.99KHz
(2) Signal Frequency: 437Hz
(3) Weight: 2.87KG
(4) Sensitivity: Small coil: 25~30cm (test 25US cent)
                        Big coil: 35~40cm (test 25US cent)
(5) Max Detection: Small coil: 1.5 meters
                               Big coil: 3.0~3.5 meters
This conclusion is elicited by testing a aluminium sheet (60cm*60cm*1cm) buried in dry soil.

Sand Casting, also known as sand molded casting, is a metal casting process characterized by using sand as Sand casting, The term "sand casting" can also refer to an object produced via the sand casting process. Sand castings are produced in specialized factories called foundries. Over 70% of all metal castings are produced via a sand casting process.

Sand casting is relatively cheap and sufficiently refractory even for steel foundry use. In addition to the sand, a suitable bonding agent (usually clay) is mixed or occurs with the sand. The mixture is moistened, typically with water, but sometimes with other substances, to develop strength and plasticity of the clay and to make the aggregate suitable for molding. The sand is typically contained in a system of frames or mold boxes known as a flask. The mold cavities and gate system are created by compacting the sand around models, or patterns, or carved directly into the sand.

Basic process

 There are six steps in this process:

 1.Place a pattern in sand to create a mold.

 2.Incorporate the pattern and sand in a gating system.

 3.Remove the pattern.

 4.Fill the mold cavity with molten metal.

 5.Allow the metal to cool.

 6.Break away the sand mold and remove the casting.
