1:ultrahigh and stable pressure machine, 2: Electronic and Automate System, 3:high-end technically antiseptic, 4:equal shrinkage - details see: https://www.machineto.com/supply-ultrahigh-water-pressure-ptfe-machine-hgi-0120-10056368

The technology of isobaric pressure has been widely used in the lined PTFE in the developed areas: Occident, Japan …Due to the bearing pressure of the isobaric machine being equal or greater than 30Mpa, the large and complicated containers connected with the PTFE powder are all produced in this method.

Traditionally, the pressure for lined PTFE powder isn't enough and generally less than 15Mpa.Due to the lacking of pressure, the PTFE powder in the steel inside wall couldn’t be pressed tightly, leading to high contractibility rate in liner after sintering, in this way, lots of disadvantages appearing, such as the fissure, bubbling, seepage.

The method used in the equal-pressure could produce some of thick wall straight pipe of the large diameter and some PTFE liner of complicated container. The quality of liners for finished products is placed in the best state when the water pressure is reached or more than 30Mpa. This is the high-end technically equipment in lining PTFE powder, also is the urgent needing in technological equipment of domestically antiseptic machine for the lining PTFE powder.

The features for the isobaric machine produced in our company are ultrahigh and stable pressure;32Mpa of maximum pressure; full-automatic control and tightening up <tightening up automatically through water pressure in one minutes >;time-program saving; flooding water, tightening up, pressure boost, pressure maintaining, depressurization, dropping water being all operated simply and safely on supervisory control desk while the density and the equal shrinkage of products are surely well-distributed and equal shrinkage. Avoiding abnormal shape of products caused by the inner stress.

The Isobaric Machine is based on the principle of Pascal” when there is an increase in pressure at any point in a confined fluid, there is an equal increase at every other point in the container”, used in shaping different PTFE products and guaranteeing the identity for finished ones, high pertinency and better effects for complicated or abnormal PTFE article of manufacture.

Structural use:

Different large-shape or abnormal products connecting with PTFE powder which the mould pressing couldn’t finish in one time, Such as the steel pipeline; abnormal bend; the liner for triple-valve body; pressing for the cutting boards and so on .

we can produce as follow :
