How TJJ Solves the Procurement Headaches of Patio Door Handle Replacement
Inconsistent Quality
Many foundries cut corners on mold precision and finishing. With 20+ years of experience, TJJ runs strict incoming raw material checks and in-process inspections. Our casting shop floor is equipped with modern spectrometers and tensile testers. Every patio door handle replacement piece is inspected for surface finish, dimensional accuracy, and function before packing.
High MOQs & Inflexible Design
We offer MOQs as low as 500 pcs per design for standard models, and even lower for prototypes. Our in-house engineering team can work from your drawings, samples, or even a concept. OEM/ODM is our core strength—we have developed over 300 custom handle designs for US and European brands.
Long Lead Times & Missed Shipments
Typical lead time from sample approval is 25–35 days. For repeat orders with stable molds, we can reduce to 20–25 days. Our logistics team coordinates FOB/CIF shipments to major US ports (LA, Houston, Savannah) with regular consolidation.
Lack of After-Sales Support
We provide a warranty on manufacturing defects (12 months), replacement parts for bulk orders, and technical documentation. Communication is handled directly by your dedicated project manager—no language barriers, no runaround.
Our foundry and QC stations – over 48,000 sq. ft. of production capacity.
