Core Technologies

Built on Precision, Integrated by Process

At ELPHA Formwork, core technology is not limited to one machine or one production step. It is the integration of all key stages of aluminum formwork manufacturing — from alloy preparation and extrusion to system design, automated fabrication, quality control, and project delivery. This is what allows us to maintain consistency, shorten lead times, and support large-scale projects with stable quality.

 

Our technology platform is built around five core strengths:integrated aluminum processing, advanced extrusion capability, system design and engineering, automated production, and standardized quality control.

Integrated Aluminum Processing

Integrated Aluminum Processing

ELPHA Formwork runs a fully integrated production model linking scrap aluminum, billet prep, extrusion, machining, fabrication, assembly, and delivery within one controlled system. By keeping processes in-house rather than across multiple suppliers, ELPHA Formwork strengthens material consistency, production coordination, and on-time delivery. The integrated chain also cuts waste, boosts repeatability, and stabilizes costs, supporting reliable long-term supply.

OEM Manufacturing

OEM is for customers who already have their own product design, section drawings, or system requirements. Clients can send ELPHA Formwork drawings for custom extrusions, formwork panels, complete formwork systems, or steel accessories, and we will develop the required molds and manufacture according to the approved design. This model is suitable for customers who need stronger customization, proprietary sections, or tighter control over product design.

 

For OEM projects involving new molds, extra lead time is required before standard production can begin. Depending on the complexity of the section and testing requirements, new mold design, turnover, and validation usually take around 1 to 3 months. After that, the regular project workflow moves into drawing finalization, production planning, manufacturing, packing, and dispatch.

ODM Manufacturing

ODM is for customers who need a faster and more practical route. Instead of starting from a completely new design, customers can choose from ELPHA Formwork's existing extrusion range, formwork components, and mold library, or let our engineering team develop the system based on project drawings using available production resources. This shortens development time and reduces the waiting period caused by new mold preparation.

 

ODM is usually the better choice when project schedules are tight, when customers want to reduce front-end development time, or when a proven and production-ready solution is preferred. The engineering process is still structured, but because it is based on existing molds and sections, the project can move faster into production.

    Flexible Manufacturing Path

    If a customer wants OEM customization but cannot wait for new mold development, ELPHA Formwork can also offer a hybrid route by using existing molds and available sections where possible, while customizing only the necessary parts. This helps shorten the schedule while still keeping part of the system tailored to the customer's requirements.

Crushing Process Overview

Aluminum formwork scrap from construction sites and recycled aluminum materials are evenly fed onto the loading apron conveyor. The materials are transported into the crusher for size reduction.After crushing, the mixed material (aluminum, iron, and dust) passes through a magnetic drum at the end of the conveyor, where ferrous materials and aluminum-attached iron are separated. The aluminum-attached iron is further processed by a secondary hammer crusher to separate aluminum from iron.

 

After iron removal, the material enters a rotary screening drum. Particles smaller than 6 mm (dust and fine aluminum) are screened out and then separated by an air separator and an eddy current separator.Materials larger than 6 mm (aluminum blocks and impurities) are further processed by an eddy current separator. By adjusting belt speed, eddy current frequency, and splitter position, aluminum is effectively separated from impurities. The cleaned aluminum is then weighed and stored in designated areas for subsequent processing.

Aluminum Formwork Production Process (Summary)

Aluminum formwork is manufactured using dedicated aluminum profiles such as flat panels, C-channels, and angle sections. Based on shop drawings, production lists, and technical instructions, production is carried out through both automatic and manual lines.

 

The process sequence includes cutting, punching/milling, welding, straightening/grinding/shot blasting, and coating to produce formwork of the required specifications and quantities.

 

The finished components are then transferred to the assembly stage, where sorting, drilling, accessory installation, stacking, and packaging are performed according to packing lists before delivery to construction sites.

  • 1.Cutting

    Cutting

    Profiles are cut to required lengths per production drawings, with first-piece and in-production batch inspections, then sorted and transferred to the next process.

  • 2.Milling

    Milling

    Holes and slots are processed according to drawings. Positioning accuracy is strictly controlled, with first-piece and sampling inspections to ensure quality.

  • Welding

    Welding

    Components are assembled and welded as per design requirements. Weld seams must be uniform, firm, and free from defects to ensure structural integrity.

  • 4. Shape Correction

    Straightening & Surface Treatment

    Deformed parts are corrected to meet flatness requirements. Surface treatment (texturing or shot blasting) is applied to achieve uniform roughness and improve coating adhesion.

  • 5 Coating

    Coating (Powder Coating)

    Powder coating is applied (single-side or double-side as required). Coating thickness and adhesion must meet specified standards to ensure durability and corrosion resistance.

  • 6 Packing

    Assembly & Packaging

    Finished components are sorted, drilled (if required), and assembled with accessories. Products are then stacked, labeled, and packaged according to packing lists before delivery to site.
