DK-300A Semi-automatic Headspace Sampler

·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 the 
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. 
5. Micro-computer control, easy to operate, with membrane keyboard, has the function of data processing starting synchronously.

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.


The designing of die casting tooling
1, According to the materials, shape and precision product, analyze technology, decide of the process.
2, Confirm the location of product in the mold cavity. Analyze parting surface, overflow system and the gating system.
3, Design the various activities of the core are assembled and fixed method.
4, Design the core-pulling distance and force.
5, Design the ejection device.
6, Confirm the die casting machine, design the mould base and the cooling system.
7, Checking the mould size and die casting machine, drawing the process flowchart and component of die casting mold.
8, Design is complete.

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.
