Lab Instrument/Semi-Automatic Headspace Sampler/Injection Sampler/Sample Instrument
The domestic current
situation of the die-casting mould
Die Casting Mould industry
has developed rapidly in our country, the total output growth significantly,
domestic die casting mold production after the United States, has become the
second in the world, become the veritable die-casting superpower. It can have
such achievement because of our country with unique broad market advantages and
relatively cheap labor force. Depend on very obvious price in the international
trade market, we produced the die casting mould which occupies a bigger
superiority, according to the situation, in the future Chinese die casting
industry development prospects are very broad.

What is the Moldflow analysis, this conception
derived fromtaiwan.
it's a precess through the computer for injection molding simulation by data
simulate software, and get data result. Then assess the feasibilty of the mold
program through these results to perfect mold and production designation.The
common software for plastic mold such as moldflow, moldex 3D and so on. And the
common software for Aluminum Die Casting Parts such as PROCAST, FLOW 3D and so
on.

·Product description
Headspace injection technique is a convenient sample pretreatment processing for gas chromatography. It's adapted for volatile component analysis. The principle is putting theÂ
sample which is under test to a pressure-tight container, and separate the volatile components from sample through heating-up, reaching balance in gas liquid (or gas solid ) phase, and then extract the top gas to analyze the volatile components and content in sample.
It can avoid complicated sample pretreatment processing, also can avoid the interference to analysis from organic solvents. Reducing the injection inlet pollutant for the gas chramography. It and can be compatible with all kinds of gas chromatography both here and aboard.
·Features
1. Sampling pump cooperate with sampling valve, negative pressure sampling, precision quantitative, high sensibility.
2. Sampling valve and sample transfer line can set temperature, to avoid sample condensation.
3. Anti-blow function for the sampling pipeline and sampling valve, to avoid cross contamination.
4. Good compatibility, can be compatible with all kinds of gas chromatography both here and aboard.Â
5. Micro-computer control, easy to operate, with membrane keyboard, has the function of data processing starting synchronously.
