Springs and Wire Forms for Agricultural Machinery — the Full Range from One Factory

The season is short. When a baler or seeder stops over a missing spring, the countdown is not in days but in harvest.

Operating conditions

What the spring faces in this industry

Seasonality: you need a manufacturer who keeps deadlines and can cover the whole product range — from small retainers to large tensioners.

  • Seasonal peak: machines run intensively on tight schedules.
  • Dust, plant residue, moisture, fertilizers and chemicals.
  • A long parts list: from small retainers to large tensioners.
  • Breakdown-driven replacement — service batches need speed.

What this means

Requirements for the spring

The full set: extension, compression and torsion springs plus wire forms made to drawings.

Wide product range

One supplier for the entire list: from a spring washer to a tensioner.

Service speed

Repair and seasonal batches are needed on short notice.

Environment resistance

Coating for dust, moisture and aggressive media, including fertilizers.

Wire forms to drawing

Not only springs: retainers, clips and hooks of non-standard shapes.

Advantages

What this means for your order

One factory — the whole range Cold coiling, hot coiling and CNC wire bending on a single site.
Prototypes in 48 hours Fast verification on the machine — before the series batch starts.
CNC wire bending Complex shapes to drawing without dedicated, costly tooling for every part.

Proof, not promises

Quality control of every batch

What removes the risks of sourcing from China

  • NDA on request Drawings and technical documentation are never shared with third parties or used for other customers.
  • Prototypes in 48 hours You test the samples first — series production is agreed only after your approval.
  • Reports for every batch Load, geometry, hardness — with measurement protocols and batch traceability.
  • Document package for EAC IATF 16949:2016 certificate, test reports and product data sheets — for declaration and customs.
  • Payment in CNY Payment terms and channel are agreed individually before the order is signed.
  • Delivery to Russia Rail, road and sea freight via the Far East. Incoterms: FOB, CIF, DAP.

How to start — three steps

  1. 01

    Send a drawing or a sample

    PDF, DWG, DXF, a sketch or a physical sample. We sign an NDA on request.

  2. 02

    Get a price and lead time

    Our engineer checks manufacturability and proposes material and coating — we reply within one business day.

  3. 03

    Test prototypes in 48 hours

    After alignment we produce prototypes and ship them to you. Then — a series batch with inspection and documentation.

FAQ

Questions about Agricultural Machinery

Do you accept orders for small batches of different parts?

Yes. For service and seasonal needs we build batches around the parts list; the minimum volume is confirmed against your list.

Can you make a part from a sketch or a sample?

Yes. We work from drawings (PDF/DWG/DXF), sketches and physical samples.

How fast do you ship seasonal batches?

Prototypes — 48 hours after the drawing and material are approved. The series lead time is confirmed once the volume is agreed.

Which materials do you use?

Spring steels 65Mn, 72A, 82B, 60Si2Mn, 55CrSi, 51CrV4, 60Si2CrMn. Wire is sourced directly from Baowu (Baosteel), Kobe Steel, Bekaert and Qingdao Special Steel, which guarantees characteristic consistency.

How do you deliver products to Russia?

We arrange rail container transport, road freight and sea shipping via Far East ports. Delivery terms are agreed per order (FOB, CIF, DAP).

Can we sign a confidentiality agreement?

Yes, we work under NDA: customer drawings and technical documentation are never shared with third parties or used for other customers.
