11. Taper Gauge for ID measurement
15-30mm GFD ID measurement by taper gauge.
Before:-
 GFD ID measurement used to be done by using venire calipers.
 Accuracy dependent on operator skills.
 Used to get variation in measurement
After:-
 Taper gauge with 0.1mm (15-30mm range) taken for GFD ID
measurement
 Accuracy not much dependent on operator skills.
 Used to get no variation in measurement.
 Easy & fast method.
 Fit for all of our 4”-14” GFD’s.

• During operation, backing is coming out from BPS
• Also mix is filtering out through BPS during molding.

(284mg)
• Baking fleece is not sticking properly to the poly.
• fleece quality is not consistent throughout the lot.
• We find two type of baking fleece (say high density & low density)
• There is wt. variation in fleece (123x23mm)
• Generally low wt. fleece is creating mix filtration issue in all sizes.

13. #1: VELVET PAPER GFDs
ACTION PLAN
1. Sourced new Velvet paper of higher GSM and better consistency – current velvet paper is 20gsm quality, we have now
purchased heavier GSM (25) which is in line with Chinese suppliers – 25 December 2022
Update: The new velvet paper sourced from Supreme Industries was rejected by our team during trials (attached in email).
After trying three suppliers from India, we have concluded the quality is consistently below par from all. Hence, we have
ordered trial lot of fleece paper from China along with our rovings which will arrive at our factory in the first week of February.
1. Providing refresher training to Coating & Lamination operators – 12 December 2022.
DESCRIPTION OF COMPLAINT
 Velvet paper lamination quality is inconsistent and there are GFDs with tearing /
loose fleece.
 Velvet paper is inconsistent and has density variation.

14. #2: HARDNESS / SOFTNESS IN FABRIC
DESCRIPTION OF COMPLAINT
 Variation in fabric stiffness. Hard fabric leads to bend issue and extremely soft fabric leads to sticky GFD issue.
ACTION PLAN – target date 15 February 2022
• Variation in fabric stiffness is an inherent property of the product. It is affected by various parameters – coating
speed, coating temperature, ambient humidity, ambient temperature and resin formulation.
• Our resin formulation is adjusted seasonally based on our historic experience and we are not facing any issues on
that front. Based on our analysis, the variation is occurring due to variation in coating speed & temperature.
• We have a reference chart for Speed & Temperature based on which the machine is operated. We also have
installed a data logger which measures the zonal temperature inside the Coating oven.
• However, we do not have the current facility to get complete realtime data of the set point vs live data, due to
which any operator adjustments or machine fluctuations cannot be captured in realtime. The same is captured
post process through the current data logger.
• To have better control on the same, our team is working on a realtime data logger monitoring solution (PLC to
HMI) wherein the live speed and temperature can be captured and cross referenced with the set parameters.
Currently. this is being done manually. By automating this process we will improve our process and create higher
operator accountability.
