Application Review
Component candidates
Electrical support parts, motor covers and reinforced brackets. Check weld-line position, insert areas and loaded interfaces. The supplier values belong to WHG25A and should not be ranked against another grade by filler percentage alone.
Assembly interfaces
Define mounting points, ribs, inserts, sealing faces and critical fits on the drawing. Agree which dimensions and functional features require sample approval.
Sample acceptance
Use representative parts made with the intended formulation and process. Specify the load, environment, appearance and inspection conditions that matter for the application.
Processing and Part Checks
Check weld-line position, insert areas and loaded interfaces. The supplier values belong to WHG25A and should not be ranked against another grade by filler percentage alone. Follow the current processing instructions for PBT WHG25A. Review gate location, weld lines, shrinkage and inspection timing with the molding team before fixing production conditions.

Material Supply and Manufacturing Support
Nylon Plastic connects engineering plastic supply with custom manufacturing. WANHAN is our cooperating compounding factory; the photographs below show its material-feeding equipment, extrusion process and laboratory.
Grade and formulation selection
Share your current grade, application and operating conditions. We coordinate the material review and identify the matching datasheet for the formulation offered.
Quality documents for your order
Specify the TDS, batch records, inspection requirements or compliance files your purchasing team needs. The documents and acceptance criteria are agreed for the quoted material.
Support beyond resin pellets
For a finished component, connect material selection with part design, tooling and molding review. Start with the drawing, expected quantity and critical dimensions.
Cooperating Factory Management-System Certificates
The supplied ISO 9001, ISO 14001 and ISO 45001 certificates identify Guangdong Wanhan as the certified entity. Their scope concerns modified plastic granules and the related management activities; it does not certify every material grade or every finished-part manufacturing service.
Review manufacturing capabilities and quality documentation. For document approval, match the legal entity, certificate scope and quoted grade.
Frequently Asked Questions
What material does this page cover?
PBT GF25 is a 25% glass fiber reinforced PBT compound supplied as pellets. The reference grade is PBT WHG25A. Electrical support parts, motor covers and reinforced brackets are candidates for review against the actual component requirements.
Does more glass fiber always mean a stronger or stiffer grade?
Check weld-line position, insert areas and loaded interfaces. The supplier values belong to WHG25A and should not be ranked against another grade by filler percentage alone. Compare the actual formulations, methods and conditioning rather than using filler percentage as a performance ranking.
Are these values a production specification?
No. They are typical reference values for PBT WHG25A. Agree the current grade, test conditions, acceptance limits and required documents for the order.
Do the images show the exact supplied color and finished parts?
The images illustrate resin appearance and possible component concepts. Confirm color and finish on the offered material and samples; the pictured parts do not establish suitability for your design.
What is required for a material replacement?
Identify the current resin and reason for changing it. Compare exact-grade data, dimensions, loads, temperature and environmental exposure, then validate the intended part before production.
What should I send for a quote or sample request?
Send the reference grade, application, color, estimated material quantity and required documents. For a molded-part inquiry, add the drawing, critical dimensions and acceptance requirements. A CAD file is optional for a material-only inquiry.
