What clamping force does Vesimentor have for plastic injection moulding?

Vesimentor operates injection moulding machines from 50 tons to 500 tons clamping force. Shot volume up to 1800 cm³, part weight up to 2000 g. This range covers small precision components, technical housings, and large structural parts in a single facility — without subcontracting between machines.

What plastic materials can Vesimentor inject?

We process the full range of commodity and engineering thermoplastics: PA (polyamide / nylon), PE, PP, ABS, POM (acetal), PC (polycarbonate), PC/ABS, PMMA — including glass-fibre filled and mineral-filled grades for structural and thermal applications. Material selection is made with the customer based on the part's mechanical, thermal, regulatory and downstream-process requirements (e.g. compatibility with vacuum metallizing, FIPFG sealing or ultrasonic welding).

What is the typical lead time for an injection-moulded order?

With existing tooling: typical first-series delivery 4 to 8 weeks from order. New tooling: 8 to 16 weeks from design freeze, depending on tool complexity. Rush orders against existing tooling can be turned in 2–3 weeks subject to machine capacity. DFM review is offered before tooling commitment to reduce iteration cost.

Is there a minimum order quantity (MOQ)?

Vesimentor is set up as a contract manufacturer — typical MOQ from 500 to 1,000 parts, lower in special cases. For prototypes and small series below 500 parts we offer vacuum-cast polyurethane or CNC-machined parts as a more economic alternative. The transition between methods is defined in the DFM phase.

What certifications does Vesimentor hold?

Vesimentor is certified to ISO 9001 (quality management), ISO 14001 (environmental management) and AQAP 2110 (NATO Quality Requirements for Design, Development and Production). The AQAP 2110 certification is exceptionally rare among injection-moulding contract manufacturers in the Baltic / Nordic region and qualifies Vesimentor for defence and critical-infrastructure programmes.

Can Vesimentor supply a finished assembly, not just moulded parts?

Yes. Beyond injection moulding we operate vacuum metallizing (chrome / gold finishes), CNC machining, FIPFG foam-gasket sealing, ultrasonic and high-frequency welding, tampoprint and assembly — all in the same facility in Pärnu, Estonia. The customer can specify a finished, ready-to-fit assembly with a single quality record and a single delivery, instead of coordinating multiple subcontractors.

Plastic Injection Moulding in Estonia — Contract Manufacturing for the Nordic and Central European Markets

Vesimentor has been a plastic injection moulding contract manufacturer in Pärnu, Estonia, since 1997. We produce engineering and technical plastic parts in volumes from hundreds to hundreds of thousands per year, and — where required — complete the product with vacuum metallizing, FIPFG sealing and potting, CNC post-processing, ultrasonic welding and in-house assembly, delivering a ready-to-install component from a single supplier.

Why Estonia for Injection Moulding

Plastic injection moulding is the standard process for high-volume, dimensionally precise plastic parts: molten thermoplastic is injected under pressure into a steel mould, cooled and ejected. The process is fast, repeatable and ideally suited to complex geometries with tight tolerances. What differentiates a good supplier is not the process itself but substrate control, quality system, engineering support and the ability to finish the part in-house. Vesimentor offers all four — combined with EU-level IP protection, short nearshoring lead times to the Nordics and Central Europe, and a defence-grade quality system (ISO 9001 + ISO 14001 + AQAP 2110) that remains uncommon among injection moulding subcontractors in the Baltic region.

Equipment and Technical Capability

Clamping force range: up to 500 tonnes, across semi- and fully automated injection moulding machines
Shot volume: up to 1800 cm³ per cycle
Part weight: up to 2000 g in a single shot
Materials processed: PA (nylon), PE, PP, ABS, POM, PC, PC/ABS, PMMA, and filled or reinforced grades (glass-fibre, mineral-filled) on project basis
2-component / over-moulding: supported on suitable machines — combining hard and soft polymers or different colours in a single part
Tooling: in-house engineering support for mould procurement, mould-in-motion development, maintenance and modifications; steel and aluminium tooling for both prototyping and serial production
Batch sizes: from pilot series through to tens and hundreds of thousands of parts per year

Our injection moulding line is part of a broader in-house plastic production capability that also covers rotational moulding for large hollow bodies and vacuum forming (thermoforming) of plastic sheet for large, thin-walled components. This means a single supplier can cover the full range of plastic forming routes, and finish the product in-house with metallizing, FIPFG sealing, CNC machining, ultrasonic welding and assembly — one specification, one quality record, one shipment.

The Integrated Process

DFM and co-design. Our engineers review the 3D model against injection moulding constraints — wall thickness, draft angles, parting lines, gate placement, ejector positions, shrinkage and warp — together with the target surface finish and downstream operations (metallizing, sealing, assembly).
Tooling. Mould design, procurement, commissioning and qualification are supported in-house. We work with the customer's preferred tool maker or propose a vetted partner, and take the tool through first-article approval together with the engineering team.
Process qualification. Cycle time, melt and mould temperatures, holding pressure, cooling and ejection are tuned to lock in a stable production window. Critical dimensions and cosmetic criteria are agreed before serial release.
Serial production. Batch traceability — raw material lot, tool usage, operator log — can be maintained for every production run, if needed and agreed.
Post-mould operations. Vacuum metallizing for decorative chrome, gold and reflector finishes; FIPFG foam gasket sealing and potting for IP65+ enclosures; CNC machining of mounting features; ultrasonic welding of assemblies.
Assembly and dispatch. Moulded parts can be assembled with inserts, fasteners, gaskets, electronics and further components in-house and shipped ready to install.

Materials and Standards

Material selection is driven by the service conditions of the part — mechanical load, temperature range, chemical and UV exposure, flame class, regulatory requirements and cost target. We work across the full range of commodity and engineering thermoplastics including PA, PE, PP, ABS, POM, PC, PC/ABS and PMMA, with access to glass-fibre-filled and mineral-filled grades for structural and thermal performance. Substrate choice is made together with the engineering team to ensure that the thermoplastic selected for the part is also compatible with downstream operations — metallizing adhesion, FIPFG bonding, weldability and regulatory class. Material qualification records, process parameters and batch traceability can be maintained for every production run, if needed and agreed, supporting customer audits, PPAP submissions and change control throughout the product lifecycle.

Vesimentor is certified to ISO 9001 (quality management), ISO 14001 (environmental management) and AQAP 2110 (NATO quality requirements for design, development and production). For defence and critical-infrastructure programmes, AQAP 2110 is a qualifying criterion that remains exceptionally rare among injection moulding subcontractors in the Baltic and Nordic region.

Typical Applications

Electronics and electrical: enclosures, sensor housings, junction boxes, control-cabinet covers, bus-validator housings, industrial enclosures requiring IP65+ when combined with FIPFG sealing
Telecommunications: cable and fibre-distribution components, outdoor-cabinet parts, gateway housings
