Powder Metallurgy Sintering Mesh Basket For Metal Parts High Temperature Sinter Process

This stainless steel sintering mesh basket is specially developed for tiny, miniature powder metallurgy components that are easy to slide and scatter during high-temperature sintering. Different from flat mesh trays, it adopts surrounding high frame structure to lock all small workpieces inside without falling off during furnace feeding, discharging and heating circulation.

Made of high-temperature resistant 310S stainless steel wire, the mesh basket can withstand long-term working temperature up to 1100℃ inside vacuum or atmosphere sintering furnaces. Integrated lifting lugs are reserved on both sides for convenient crane loading and unloading, greatly improving the operation efficiency of small-batch intermittent sintering production lines. It is widely matched with box vacuum sintering furnaces, small pit furnaces and laboratory heat treatment equipment.

Put miniature metal blanks into the mesh basket, lift the whole basket into vacuum sintering furnace via lifting lugs. The hollow mesh wall allows full circulation of hot gas inside the furnace cavity, achieving uniform heating of all small workpieces. The high surrounding frame limits workpiece displacement, avoiding material loss caused by rolling during furnace operation. After sintering is completed, the whole basket can be lifted out directly for rapid material turnover.

1.Mesh Surface: Plain woven high-temperature metal wire mesh with uniform holes for optimal heat and gas flow

2.Reinforced Edge: Solid stainless steel round tube fully wrapped frame, anti-deformation under load, no mesh cut during stacking

3.Welding Craft: Full seamless welding, no cracking or wire shedding under long high-temperature operation

4.Standard Material Options:

1. 310S (2520): Max temp 1350℃, best anti-oxidation, top choice for vacuum sintering
2. 309S (2320): Max temp 1200℃, cost-effective for atmosphere sintering
3. 304: For low-temperature degreasing and temporary part transfer

1. High Surrounding Anti-Scattering Frame Integrated bending high fence prevents miniature gears, small fastener blanks and tiny metal parts from rolling out during heating and transfer, greatly reducing workpiece waste rate.

2. Reserved Lifting Lugs for Easy Batch Handling Custom integrated lifting ears on two sides, compatible with workshop cranes and material trolleys, one-time loading & unloading of a whole basket of small parts, saving labor cost.

3. Hollow Mesh Uniform Heat Conduction Uniform mesh structure ensures hot air or vacuum atmosphere penetrates all parts inside the basket, no internal temperature dead zone, consistent sintering density for tiny components.

4. Deform-Resistant Welding Structure Full argon arc seamless welding at all joints, no cracking or deformation after repeated high-temperature heating & cooling cycles, long service life over 3000 production batches.

Q1: How to choose between 310S and 309S mesh trays?

A: Choose 310S for vacuum sintering over 1250℃ and long service life; select 309S for atmosphere sintering below 1200℃ to cut procurement cost.

Q2: Will the tray warp under high temperature?

A: Full wrapped thick tube edge + full welding structure effectively prevent warping under rated single-layer load; reinforced double frame design available for heavy loading.

Q3: Will fine powder leak out through mesh holes?

A: Custom dense small-aperture mesh or double-layer composite mesh to stop fine powder leakage and furnace contamination.
