Custom-made steel moulds for producing concrete frames, pipes and precast parts with dimensional accuracy, controlled height, uniform compaction and cleaner demoulding.
This line is designed for drainage, sanitation and channel pieces. The assembly, transport and interior photographs are used to explain dimensions, supports, compaction and clean release of the part.






The key is not only to close a mould: height, internal void, stability, compaction and extraction must be controlled so each part comes out with industrial continuity.

The assembly defines the part geometry, regulates height, supports compaction and facilitates demoulding without damaging the frame or pipe.
Steel frame that defines the shape of the frame or pipe and provides dimensional stability in each cycle.
Internal element that determines the hollow volume of the part and facilitates clean extraction.
Adjustable system to define the exact height of the part and adapt the mould to the project.
They distribute the load, stabilise the process and participate in the tongue-and-groove of the part.
Integrated in the centre of the mould to improve compaction and reduce defects in the concrete.
Work is based on drawing, sample, part reference or production need. The critical points are geometry, height, supports, compaction, handling and demoulding.
Section, length, height, thicknesses and geometry defined according to the precast part.
Outer mould, core or inner core, delimiting jacket, support rings and vibration areas.
Delimiting jackets to adjust height and adapt the assembly to different needs.
Cores and solutions prepared for vibrators when the process requires them.
Design oriented to assembly, opening, loading, transport and workshop maintenance.
Control of supports, fits, stability, tongue-and-groove and critical points before delivery.
The page brings the product down to earth: what part is to be manufactured, what controls it needs and how that becomes a steel assembly prepared to work.
Dimensions, height, thicknesses, intended use and real workshop conditions are reviewed.
Outer mould, core, jacket, rings, supports and vibrators are planned with practical logic.
The workshop resolves rigidity, fits, welding, finish and handling points before delivery.

Resistant and modular design adaptable to different dimensions, formats and production needs.
Delimiting jackets to control exact height and provide adjustment margin by project.
Vibrator cores designed to improve compaction and uniform concrete structure.
Reliable construction for demanding work, repetition and production continuity.
Other Relente manufacturing lines for precast concrete and deep drilling.
We manufacture steel moulds for concrete box culverts, concrete pipes and heavy precast concrete pieces, with stable geometry, core, outer mould, limiting jacket, supports and closing systems designed for compaction, demoulding and repeated cycles.
When a precast manufacturer needs to produce box culverts, galleries, pipes or special pieces, the mould must control faces, radii, thicknesses, height and supports from the first cycle.
The mould geometry affects how concrete enters, how it compacts, where stresses appear and which areas need stiffness to avoid deformation.
A good design reduces snagging, impacts, marks on the piece and downtime. Openings, closures, supports and extraction must be solved before manufacturing.
The project may start from a drawing, sample, existing mould or production need. The solution is adjusted to real dimensions, tolerances and industrial use.
A precast box culvert or pipe requires dimensional stability and repetition. The mould must maintain geometry, allow uniform compaction, make demoulding easier and withstand cleaning, handling and maintenance without losing adjustment.
The outer mould defines visible faces and contour; the core controls the inner void, radii, thicknesses and extraction. Both must work aligned.
Limiting jackets, rings, bases, supports and auxiliary tools help close the geometry, maintain height and repeat positioning between cycles.
Useful height, closures, reinforcements and lifting points are defined so the mould withstands real plant work without deformation or production delays.
When the piece requires specific dimensions, industrial repetition or reliable demoulding, the mould must be designed around the final product and the manufacturing process, not as a generic solution.
Moulds for box culverts, galleries, crossings, channels and rectangular-section pieces where faces, radii, thicknesses and dimensional stability matter.
Assemblies for manufacturing pipes and cylindrical or special pieces with control of diameter, length, support, closing and extraction.
When the piece does not fit a standard mould, geometry, tolerances, handling, compaction and expected maintenance are studied.
If a mould works but fails because of play, deformation, closing, wear or poor demoulding, reinforcement, adjustment or modification can be assessed.
Mould quality is visible when the piece comes out the same again and again. That is why materials, thicknesses, reinforcements, support points, opening, lifting, cleaning and maintenance are reviewed before manufacturing.
Outer and inner dimensions, length, height, radii, thicknesses, visible faces, tolerances, reinforcement position and expected finish.
Concrete type, vibration, compaction, cycle rhythm, filling system, opening sequence and space available in the plant.
Cleaning, wear, access to critical areas, lifting points, future repair and handling safety during daily work.
Box culvert, pipe, gallery, channel, manhole, special piece or heavy precast item from drawing.
Dimensions, radii, thicknesses, height, length, tolerances, visible faces and critical areas.
Outer mould, core, jackets, rings, supports, closures, opening system, lifting and extraction.
Cycle volume, type of compaction, vibration, cleaning, maintenance and plant conditions.
Practical answers to prepare a technical enquiry without closing dimensions that depend on the project.
Yes. Moulds can be manufactured for box culverts, galleries, crossings, channels and rectangular-section pieces from drawing, sample or production need.
Yes. Diameter, length, thickness, support, closing system, core, outer mould, extraction and expected work rhythm are studied.
Drawings, dimensions, photos of the piece or existing mould, concrete type, compaction system, expected production and current problem if it is an improvement.
It can be assessed. Deformation, play, closures, wear, stiffness, handling and the real possibility of improvement without compromising the final piece are reviewed.
The objective is to deliver an assembly manufactured with use criteria: handling, opening, closing, cleaning, maintenance and technical validation before entering production.
