TONGHOU / FAQ
Answers to 10 questions about choosing sheet, flocked inserts and preparing samples. Wenzhou Tonghou Plastic Products Co., Ltd. · Updated 27 September 2026.
Start with samples similar to your product and compare thickness, surface finish and forming results. Ask about material sourcing, batch records, inspection methods and consistency on repeat orders. Tonghou produces PET, PS, PP and flocked sheet in-house alongside thermoforming. Send a product photo or drawing so we can discuss the material and process.
Compare flat sheet and formed samples from the same batch to see whether shedding appears before or after forming. Check whether it is concentrated around deep cavities or corners where the sheet stretches. Review adhesive coverage, surface preparation, fibers, electrostatic conditions and curing records to narrow down the cause. Use the same rubbing method, cycle count and acceptable fiber-loss limit when comparing samples.
For an initial enquiry, use 0.13–1.5mm for PET, PP and PVC, 0.25–3.5mm for PS, and 400–800mm width as reference ranges. Send the application, dimensions, colour and flock finish so we can confirm a suitable material and size combination. Final specifications are agreed through drawings and samples before ordering.
Plaster tooling can help check an early shape or fit. For surface finish and production planning, consider electroformed copper or aluminium tooling according to dimensions, quantity and tool life. Send photos or drawings with the material, critical dimensions and the question you want the sample to resolve. We can then confirm tooling and timing, followed by acceptance samples before production.
