2. Brief Introduction:
 
HFD-C Multi-Function Natural Electrical Field detector is a water detector which is specifically designed for depths of 300m.
It monitors the changes of underground electrical resistivity by measuring the intensity of natural electrical field, then analysing the position and depths of underground water.
This instrument solved a major issue, which is freqency choosing and anti-jamming in a natural electrical field.
It uses waterproof shell and touch screen, which is easy of handling and easy to learn.

Hfd-C Portable Underground Water Detector

HFD-C Multi-Function Natural Electrical Field detector is portable, efficiency, easy-handling and accurate analysis. It is auto-measuring which could show data and curves clearly and simple.
Comparing with traditional DC electrical water detector, its speed of measuring was increased more than 8 times, but the instrument weight was decreased 8 times. 
In the past 20 years experience, we won a high reputation and were high acclaimed by our customers.

3.Compare with traditional geo-electrical water detectors:
Traditional geo-electric water detectors HFD-C Ground Water Detector
Heavy meter and complicated wiring due to manual power supply. No need power supply, use natural electric field and 20 meters receiver pole, through special amplify method to complete survey.
Need 3-5 persons or more to operate it and cause heavy work and low efficiency. 2 people are enough to finish the work High efficiency
Heavy, about 50-500KG, hard to remove. Light weight, <5KG, easy to carry.
Need to convey data to PC and use various software to draft and analyze. We configure a 4G U-disk storage to introduce the data! Then you can do various operations for the measured data.
Professional operations and expensive Very practical and low cost
Just know water location and depth Can know water location, water supply direction, water depth and water outflow.

4. Application:
Metal and non-metal ore survey;
Decrease mineral invest venture and increase exploration success rate;
Underground water detect in all kinds of the geological conditions;
Meet demand of drinking water, industrial usage and agricultural irrigation;
Engineering geological prospect and disaster geological detect;
Coal goaf, archaeological mining, city exploration and non-metal pipe survey.
 
5. Main features:
Fast and high efficiency.
Easy to carry.
Easy operation.
Good precision and high accuracy.
Very practical and low cost.
Flexible array-traditional and unique array method.

6. Advantage:  
 
1. It is integrated into an aluminum alloy tool case, then can be carried freely.
2. Built-in charging lithium batteries, can fast charge for 4 hours, then you can use it for 16 hours.
3. Special rough measurement and fine measurement electrodes largely improve the speed and precision of equipment.
4. Multiple anti-jamming design and unique anti-jamming modes to choose largely increase the accuracy and stability of data.

"Gravity Die Casting. A permanent mould casting process, where the molten metal is poured from a vessle of ladle into the mould, and cavity fills with no force other than gravity, in a similar manner to the production of sand castings, although filling cn be controlled by tilting the die."

Gravity Die Casting

Sometimes referred to as Permanent Mould, GDC is a repeatable casting process used for non-ferrous alloy parts, typically aluminium, Zinc and Copper Base alloys.

The process differs from HPDC in that Gravity- rather than high pressure- is used to fill the mould with the liquid alloy.

GDC is suited to medium to high volumes products and typically parts are of a heavier sections than HPDC, but thinner sections than sand casting.

There are three key stages in the process.

  1. The heated mould [Die or Tool] is coated with a die release agent. The release agent spray also has a secondary function in that it aids cooling of the mould face after the previous part has been removed from the die.
  2. Molten metal is poured into channels in the tool to allow the material to fill all the extremities of the mould cavity. The metal is either hand poured using steel ladles or dosed using mechanical methods. Typically, there is a mould [down sprue" that allows the alloy to enter the mould cavity from the lower part of the die, reducing the formation of turbulence and subsequent porosity and inclusions in the finished part.
  3. Once the part has cooled sufficiently, the die is opened, either manually or utilising mechanical methods.

Advantages

  • Good dimensional accuracy
  • Smoother cast surface finish than sand casting
  • Improved mechanical properties compared to sand casting
  • Thinner walls can be cast compared to sand casting
  • Reverse draft internal pockets and forms can be cast in using preformed sand core inserts
  • Steel pins and inserts can be cast in to the part
  • Faster production times compared to other processes.
  • Once the tolling is proven, the product quality is very repeatable.
  • Outsourced Tooling setup costs can be lower than sand casting.
