- Dimensional stability within tight tolerances
- Smooth surface finish that reduces your machining time
- Minimal internal stress that prevents cracking during processing
This means lower scrap rates for your manufacturing operations. You save money on every tool you produce.
Complete Manufacturing Control
From raw material to finished bar, everything happens in-house. We don't outsource critical steps.
Our integrated workflow includes:
- Custom alloy formulation based on your application
- Precision melting and metallurgy control
- Controlled extrusion processes
- Heat treatment optimization
- Final inspection and testing
You benefit from consistent quality. No surprises. No batch-to-batch variations that disrupt your production schedule.

Primary Applications in Oil & Gas Operations
Dissolvable Frac Plug Components
Your multi-stage fracturing operations demand reliable temporary isolation. Our High-Temperature Dissolvable Magnesium Alloy Round Bar serves as the core material for plug mandrels and slips.
During fracturing, these components maintain 70 MPa pressure seals. After stimulation completes, they dissolve completely in wellbore fluids.
No coiled tubing. No milling operations. Just clear wellbores ready for production.
This saves you significant time and operational costs on every well.
Dissolvable Ball Seats and Drop Balls
In multi-stage incitement, you require exact arrange confinement. Components machined from our circular bars give brief seats that seal beneath pressure.
When uncovered to high-salinity completion liquids, they corrupt on your plan. The wellbore opens actually for generation flow.
Geothermal Completion Tools
Standard polymers come up short in extraordinary geothermal conditions. Your high-temperature applications require superior materials.
Our magnesium amalgam bars keep up mechanical properties where other materials lose quality. They give basic keenness amid establishment and controlled disintegration afterward.
Zero flotsam and jetsam remains in your store. The whole component breaks down at the atomic level.
How Our Manufacturing Process Protects Your Investment?

Frequently Asked Questions
What makes your circular bars appropriate for high-temperature wells?
Our combination definition incorporates particular components that keep up mechanical quality at hoisted temperatures. We've tried execution up to 200°C in HTHP research facility conditions. The grain structure remains steady, avoiding untimely debasement whereas protecting the disintegration capability you require after breaking completes.
How do you control the disintegration rate?
Dissolution rate depends on amalgam composition, grain measure, and downhole conditions. We alter the metallurgical parameters amid fabricating to target your particular necessities. If you require speedier disintegration in low-salinity situations, we alter the cathodic stage dissemination. For slower disintegration in forceful brines, we alter the defensive film arrangement characteristics.
Can you create bars bigger than 300mm diameter?
Our current greatest is Ø300 mm with ensured quality. For bigger distances across, contact our designing group. We're ceaselessly extending capabilities based on client needs.
What's the least arrange quantity?
This depends on the detail. For standard sizes, we oblige littler orders. Custom details ordinarily require bigger minimums to legitimize setup costs. Reach out and we'll work with your volume requirements.
Do you give fabric testing data?
Yes. Each shipment incorporates comprehensive test reports from our CNAS-accredited lab. You get mechanical property information, chemical composition investigation, and grain structure documentation. If you require extra testing, we facilitate third-party verification.

How do I get begun with a custom formulation?
Email us your well conditions and execution prerequisites. Our building group will survey your application and prescribe an combination determination. We'll give a citation and timeline inside three trade days.
What quality certifications do you maintain?
We work beneath ISO 9001, ISO 14001, and ISO 45001 administration frameworks. Our research facility holds CNAS accreditation, and we keep up HSE compliance. Documentation bundles back your provider capability process.

Can you offer assistance with apparatus plan optimization?
Absolutely. We collaborate with clients on material-structure co-design. Our encounter with dissolvable components makes a difference you maintain a strategic distance from common plan botches that lead to untimely disappointment or fragmented disintegration.
