At Ladata, we believe every successful in-mould assembly starts with a well‑engineered pre‑mould. From the moment your concept enters our system, we design and optimize the pre-moulded structure to seamlessly support insert integration, dimensional stability, and overmould compatibility.
Our Pre‑Mould Design Assistance service is built on deep cross‑disciplinary expertise—from precision metal stamping and plastics engineering to mould design and automation—delivering manufacturable, robust substrates for multi-stage moulding processes.
At Ladata, the pre‑mould is not an afterthought—it’s the critical base that determines mechanical strength, sealing performance, and electrical function. Our engineering team collaborates with yours to define the optimal substrate design that integrates:
Stamped inserts (leadframes, busbars, terminals)
Mounting or snap-fit features
Flow paths that support overmould uniformity
Critical sealing zones and undercuts
Backed by Layana’s 20+ years of in-mould assembly experience, Ladata ensures every pre-mould is built to perform under demanding applications, from EV modules to medical sensors.
As the UK division of Layana Taiwan, Ladata carries forward a fully integrated approach: designing, stamping, moulding, and validating all components within one tightly controlled process.
Our pre‑mould design work combines:
CAD development for high-complexity 3D geometries
Insert seating tolerance studies
Shrinkage and thermal expansion balancing
Overmould anchoring and sealing strategy integration
We tailor your 3D model to include zero-clearance insert pockets, undercuts, alignment pins, and mechanical locks—ensuring that your insert stays in position during high-pressure overmoulding.
Our designs consider thermal mismatch, bonding behaviour, and interface tolerances between metal and plastic. This prevents stress cracks, warping, and functional failures down the line.
We engineer pre‑mould structures with the second shot in mind—supporting perfect encapsulation, flow balance, and cosmetic quality. Sealing ribs, draft angles, and flow channels are all tailored for the full in-mould journey.
Complete Control from Insert to Overmould
Backed by decades of precision manufacturing expertise from Layana, Ladata stands apart by offering fully integrated insert solutions. Unlike others who depend on external suppliers for metal components, Ladata—leveraging Layana’s in-house metal stamping and toolmaking—can design, stamp, and integrate all inserts under one roof. This ensures exceptional control over tolerances, alignment, and interface performance.
Engineering Rooted in Real-World Mould Behaviour
Our team uses mould flow analysis, thermal simulation, and decades of trial data to refine every detail of your pre‑mould—balancing manufacturability with functional requirements.
Cross-Functional Collaboration for Faster Results
Plastic engineers, tooling specialists, and metal stamping experts work in parallel to eliminate bottlenecks and resolve design issues early—reducing cost and compressing timelines.
Experience Across Demanding Industries
Ladata supports projects for power electronics, automotive EV, medical, and smart devices—ensuring pre‑moulded substrates meet high safety, performance, and regulatory expectations.
Your questions answered
A pre‑mould is the first-shot plastic structure in a two-stage in-mould assembly. It serves as the foundation into which a second plastic material is injected (the overmould). Pre‑moulds house inserts like terminals, leadframes, or busbars, and must be designed to ensure proper retention, sealing, and compatibility with the second shot. Poor pre‑mould design leads to defects, failures, and costly tooling revisions.
Involving Ladata at the design stage—before tooling or prototyping—allows us to optimize the insert layout, premould structure, and overmould strategy together. We help validate critical dimensions, draft angles, flow paths, and mechanical locking features before they’re finalized, saving cost and improving first-shot success.
Yes. Ladata benefits from Layana’s in-house stamping capabilities, supporting the development of copper, brass, and hybrid alloy leadframes, terminals, and busbars. This close collaboration enables smooth integration between insert geometry and pre-mould form, helping reduce alignment challenges and tolerance stack-ups throughout the process.
Our pre‑mould design is ideal for:
EV connectors, charge ports, and power modules
Automotive sensors and isolation chambers
Medical devices requiring multi-shot or hybrid materials
Power electronics like inverters and battery systems
Smart locks, IoT enclosures, and control housings
Whether your application requires high electrical performance, sealing, mechanical strength, or all three, Ladata’s designs ensure your assembly functions reliably from first shot to final use.
