Dutch term or phrase: opgespoten tot een bijna moleculair niveau
This is actually a very creatively written catalogue about decorative lighting made from carbon fibre (really beautiful). Here, the focus is on some technical info, specifically how carbon fibre is made.

In het productieprocédé - pyrolyse: een goedbewaard geheim, zelfs toverkunst genoemd - worden die vezels onder heel hoge druk en een temperatuur van 3.000° **opgespoten tot een bijna moleculair niveau**.

Opgespoten seems to make no sense. I've been asked to translate this job quite freely, so can anyone suggest how to (re)phrase this. Current translation (but not sure if ** is correct):
Carbon fibre is made by a chemical process called pyrolysis – a well-kept secret with almost magical overtones – in which the fibres are heated at 3000°C and under very high pressure **until thermal decomposition**.

English translation:created at virtually molecular level
Explanation:
'opgespoten' must refer to the actual creation of individual fibres at almost molecular level. maybe you could refer to nanoscience too.

afaik pyrolysis inolves 'thermal decomposition', but this is about forming new products through this process

Based on Kitty's info, I moved away from the source (which didn't seem correct to me) and the artist himself OK'd "[pyrolysis] ... in which, under very high pressure and at a temperature of 3000°C, precursor fibres (e.g. acrylic) are transformed into carbon fibre at molecular level." He actually changed "at almost the molecular level" to "at molecular level". Thanks to you all - and particularly Kitty - for the discussion and extra info.

neutral  philgoddard: I think "created" is too vague. It's a specific process.

Reference information:
Carbon fibers are filaments of carbon that can be used to make very strong yarns and textiles. Carbon fiber items are often produced by spinning and weaving the desired item from fibers of a suitable polymer, and then pyrolyzing the material at a high temperature (from 1,500–3,000 °C or 2,730–5,430 °F). The first carbon fibers were made from rayon, but polyacrylonitrile has become the most common starting material. For their first workable electric lamps, Joseph Wilson Swan and Thomas Edison used carbon filaments made by pyrolysis of cotton yarns and bamboo splinters, respectively.
https://en.wikipedia.org/wiki/Pyrolysis

Carbon fibers can be manufactured by converting a precursor fiber, such as a spun polyacrylonitrile (PAN) fiber, in a multi-step process in which the precursor fiber is heated, oxidized, and carbonized to produce a fiber that is 90% or greater carbon. The resulting carbon fibers can be molded into high strength composite materials for structural applications, used in their pure form for electrical and friction applications, or can be further processed for use in adsorbent, filter, or other applications. In particular, composite materials have been developed in which carbon fibers serve as a reinforcing material in a resin, ceramic, or metal matrix.
