Subcontract Vibratory Finishing you can plan around

Delivering consistent results, through short lead times, full documentation on request, and sample runs available.

What is vibratory finishing and why it matters

In manufacturing, the last few microns often decide whether a part passes inspection or holds up in service. Vibratory finishing is a mechanical process that removes burrs, smooths edges and polishes surfaces by tumbling components with media and compounds in a vibrating bowl or trough. It delivers uniform results across batches without the labour and variability of hand finishing.

Why subcontract vibratory finishing

Hand finishing is slow, variable and expensive. PDJ’s subcontract vibratory finishing gives you consistent deburr, controlled edge radius and cosmetic polish without adding headcount. You get a proven process sheet, short and dependable lead times, and audit-ready documentation so bottlenecks stop dictating ship dates.

What “recipe-locked” means

We run a representative sample to tune media, compound, concentration, load, presentation, cycle time and rinse or dry. We record the edge roughness and condition. The same inputs produce the same outputs, every time.

What we finish, where we shine

Precision machined parts in aluminium, steels, stainless and titanium where edge condition and tight Ra bands matter
Additive and MIM components that need smoothing without losing detail
Laser cut, punched and stamped parts that need true deburr with a uniform surface
Pre-treatments, pre-anodise, pre-plate and pre-paint surface improvement
Superfinishing to 0.05 to 0.03 Ra where geometry allows
Sectors, aerospace, medical, automotive, additive manufacturing and general engineering

How it works

Free sample analysis
Send a small batch with target finish and edge radius. We tune media, chemistry and cycle time, then return finished parts with notes, including Ra or Rz, edge condition and handling.
Your process sheet
Approve the outcome. We control the variables and lock the recipe so every run is repeatable and audit-ready.
Short, dependable lead times
Tell us quantity and required date. We confirm the latest incoming window and hit it.
QA and documentation
Traceability, photos and certificates of conformity on request.

Subcontract or buy a machine, a practical guide

Subcontract with PDJ

Best fit, new programmes, irregular or seasonal volumes, pilot batches, limited floor space and tight deadlines. No capex, no maintenance, no operator training and no media logistics. Typical outcomes, less hand finishing, stable cycle times, protected ship dates and more completed orders.

Buy your own machine

Best fit, steady, high volumes in a dedicated daily process. You gain schedule control and lower unit cost at scale, and you own capex, installation, chemistry and media management, training and QA. Many customers validate with PDJ, then move to an in-house cell when volume justifies it. We help specify size and capacity, advise on new or refurbished machines, load your proven recipe and train operators.

Outcomes you can bank on

Consistent deburr and controlled edge radius, faster assembly and less premature wear
Uniform satin or polish, fewer cosmetic rejects and better perceived quality
Less hand finishing, lower variation and labour cost
Predictable cycle times, easier planning and happier schedulers

Fast decision checklist

FAQs

How fast is “fast”?
Typical turnaround is 24 hours once your recipe is validated. Share date and quantity and we confirm an achievable window.

Can you hit my Ra or edge radius?
Yes, from deburr with controlled edge break to cosmetic satin or superfinish to 0.03 Ra where geometry allows. We validate on samples first so production is not the test bench.

What if requirements change mid-project?
We re-validate on samples, update the process sheet and resume production so live work stays stable.

Do you handle regulated work?
Yes, aerospace, medical and automotive programmes with the documentation you specify, photos, certificates of conformity and lot traceability. PDJ is ISO 9001 accredited and is working toward AS9100D.

What if my volumes take off?
Keep running with PDJ or we help you justify and spec an in-house cell, supply new or refurbished machines, load your proven recipe and train your team.
