Ukukhiqizwa okusheshisiwe (1-2 weeks for standard, 3 weeks for custom) iyatholakala ngokungeziwe 25% imali.

Q: Does Excellence provide material testing reports for screw components?

A: Yebo. All screw components come with a material certificate (certificate of analysis – COA) verifying material grade, ubulukhuni, and chemical composition. For HIP materials, we also provide HIP processing reports (ukuminyana, porosity) and non-destructive testing (I-NDT) imibiko (ultrasonic testing for internal defects).

Q: How do I select the right material for my extrusion application?

A: Excellence’s technical team provides a free material selection guide based on:

• Uhlobo lwezinto (virgin/recycled, filled/unfilled, corrosive/non-corrosive).
• Extrusion temperature (high-temperature engineering plastics vs. standard polymers).
• Production volume (24/7 operation vs. batch production).
• Isabelomali (upfront cost vs. izindleko eziphelele zobunikazi).

We also offer a trial program (30-day test of a sample screw) for new customers to validate performance before full purchase.

Q: What warranty is provided for Excellence screw components?

A: Standard warranty: 12 months for 38CrMoAl and 316L screws, 24 months for W6Mo5Cr4V2 and HIP material screws (covers manufacturing defects and premature wear <0.5mm in the first year). Extended warranty (36 izinyanga) iyatholakala ngokungeziwe 15% imali, including annual wear inspections.
