Deep Throat Presses: The C1S Series

Throat depth options from 600 to 1,300 mm on a dedicated 45-160 ton C-frame series, built for wide sheet and perforated products.

The Deep Throat Press in This Range: C1S

Throat depth — the distance from the centre of the bolster to the frame behind it — decides how deep a sheet or part can reach into the press. The manufacturer's dedicated deep throat series is the C1S, published at 45-160 tons, with throat depth options from 600 to 1,300 mm: several times the throat of a standard gap frame press of similar tonnage. The official product page describes the C1S as a deep-throat variant built for wide sheet and perforated products.

Selected per-model specifications for the C1S — die height, bolster and slide dimensions, cushion and motor per model — are published on the C-frame press page, alongside the standard-throat C1N and A1 tables it is compared against.

What the Extra Throat Buys

The manufacturer's C1S series is its dedicated deep throat series, specially designed for wide sheet and perforated products and published at 45-160 t, with the throat depth customized to the sheet width the customer runs. In the manufacturer's own description, the press is customised on the customer's requirement for throat depth — the distance from plate centre to press frame — and that depth relates to the metal sheet width the customer is using.

Documented Features of the C1S

  • Precision grade: the published C1S table states GB (JIS) Class 1 precision.
  • Overload protection: the fast-response hydraulic overload protection system is a published standard feature on the C1S page.
  • Variants: the published table lists all five C1S models in V-Type form, each with variable and fixed SPM figures.
  • Family context: the C1S carries the C-frame family's documented feature set — high-torque low-noise clutch and brake, forced lubrication with monitoring — and its own page publishes a rigid frame with less deflection.

Deep throat work is one branch of the gap frame family: the standard-throat single crank models are on the single crank press page, and the whole family is tabled on the C-frame press page. The hydraulic series, documented for drawing work on its own pages, is at hydraulic presses.

Frequently Asked Questions

How deep is the throat on a C1S?

The manufacturer's C1S page publishes throat depth options from 600 to 1,300 mm — the option is selected per model and fixed in the quotation.

What work needs a deep throat press?

Wide sheet and perforated products are the manufacturer's stated case: work where the sheet must pass deep into the press so the die can reach the middle of the panel.

What tonnage does the deep throat series cover?

45 to 160 tons in the published C1S table, with strokes of 80-200 mm at 20-100 strokes per minute.

Is the C1S precision graded?

Yes — the published C1S Technical Datas table states GB (JIS) Class 1 precision, the same grade as the C1N, D1N and M1N tables.
