What Are You Trying to Estimate?
What will the finished roll diameter be?
Use the roll diameter calculator before discussing rolling machine setup or element size planning.
Question 02How much membrane sheet do we need?
Estimate flat sheet usage for purchasing, batch preparation and early production cost planning.
Question 03How much spacer or carrier should we prepare?
Connect spacer and carrier estimates with material data sheets and cutting preparation.
Question 04How much glue or tape will be consumed?
Plan production consumables before confirming batch quantity and material specifications.
Question 05What output can this line support?
Use capacity estimates to compare semi-automatic and fully automatic production options.
Question 06Which equipment or material should we choose?
Move from calculator results into selection guides for equipment, materials and line planning.

FAQ
Calculator Notes
Are WECOME calculator results final production specifications?
No. Calculator results are planning estimates. Final values should be confirmed according to actual membrane design, raw material specifications, machine configuration and production tolerance.
Can these calculators be used for 1812, 4040 and 8040 RO membrane elements?
Yes. The calculator library is designed around common domestic and industrial RO membrane element production scenarios, including 1812, 4040, 8040 and customized element sizes.
Why do calculator results need engineering confirmation?
RO membrane element production involves material thickness, compression, adhesive behavior, rolling tension, machine settings and quality control requirements. These factors can change final production values.
