Resources
HEMSUN ENGG. INDUSTRIES provides technical Resources, calculation formulas, and material engineering guidelines compiled from 30+ years of manufacturing experience. Explore guides and datasheets below.
Working principle and engineering architecture
Use this section in the order your question sits. If you are choosing a process, start with Technical Guides. If the process is settled and you need a number, go to Technical Data for the property or to Tools & Calculators for the sizing. If you are preparing an RFQ, the FAQ covers what HEMSUN needs on a drawing and how export shipments are documented, and Downloads has the material datasheets to attach. Every guide links back to the product or machine page it relates to, so a technical answer leads to the item that delivers it rather than ending in isolation.
The guides are written for engineers specifying a part or a press, not as marketing copy. Where a figure is quoted — compaction pressure in MPa, a shrinkage percentage, a tonnage from F = P × A — it is stated with the condition it applies under, because a number without its condition is not useful on an RFQ. Material data is given by grade rather than as a single PTFE figure, since a bronze-filled compound and an unfilled one behave differently under load, temperature and chemical attack.
