Quality Control

In-house manufacturing

Built under one roof.
Checked at every step.

Our team controls the production process in-house, from material selection to final inspection. That means stable quality, reliable lead times and a clear point of contact for every wholesale drinkware order.

01

Raw material preparation

Qualified materials, ready to perform.

Food-grade stainless steel and approved components are checked before production begins.

02

Tube cutting & forming

Precise dimensions from the start.

Sheets are cut, shaped and formed into inner and outer shells with repeatable tolerances.

03

Welding & vacuum insulation

Insulation that holds its promise.

Welded shells move through vacuum insulation technology to improve heat retention.

04

Surface treatment

Finishes made for your brand.

Polishing, powder coating, spraying and printing create smooth, consistent surfaces.

05

Quality inspection

Nothing leaves unchecked.

Appearance, sealing, vacuum performance and coating quality are reviewed before packing.

06

Packaging & shipment

Ready for the next destination.

Products are packed, labeled and prepared for efficient export service worldwide.

Inspection protocol

Our 4-step inspection process.

We do not just manufacture. We verify excellence against the standards your customers expect.

01

IQC: Material verification

Before any coil enters our warehouse, spectrometer analysis verifies the correct Nickel/Chromium ratios for SUS304 (18/8).

  • Composition check for food-grade stainless steel
  • Lead-free and BPA-free material screening

02

100% vacuum insulation test

Every double-wall vessel is tested for heat retention, rather than relying on random sampling.

  • Automated temperature-sensing line
  • Any heat transfer to the outer wall is rejected

03

Coating & logo durability

Destructive testing protects the brand image on every custom logo tumbler.

  • Cross-cut test with industry-standard 3M tape protocols
  • Dishwasher simulation across 20+ wash cycles

04

FQC & pre-shipment

Final quality control follows AQL 2.5 (Major) / 4.0 (Minor) before commercial orders leave the facility.

  • Drop test from a 1-meter height
  • Leak-proof shaking test with boiling water

In-house laboratory

Testing with hard data.

We validate manufacturing precision before mass production orders are released.

LAB / 01

Thermal performance test

BS EN 12546-1:2000

Filled with 95°C water, the vessel must remain above 55°C after 24 hours, depending on capacity.

Material composition

Confirming the alloy is consistent with the approved specification.

Coating adhesion

Cross-cut testing ensures the finish stays attached to the surface.

Leakage proof

Sealing and lid interfaces are checked before packaging.
