Plastic Injection Molding

Plastic injection molding is the classic technology for serial production of plastic parts: molten plastic is injected under pressure into a metal mold, cools, and takes its shape. The big barrier is the mold itself — traditionally an expensive investment that doesn’t make economic sense for smaller runs. At LASKOR, we designed our process around that problem: a two-stage approach combined with making the tooling ourselves brings injection molding within reach for small and medium batches.

First a Prototype Mold, Then the Series

Before committing to an expensive metal tool, we build a prototype mold from heat-resistant plastic or specialized casting resin. On this prototype we produce 2–3 trial parts in the same material you have chosen for the series. What you get back is not a render — it is a real, physical sample: you can check geometry, fit, wall thickness, strength, and appearance. If something needs adjustment, changes at this stage are cheap and fast. Only once the part fully meets your requirements do we move on to cutting the production mold.

Aluminum Mold on Our Own CNC

The production mold is milled in-house, from aluminum, on our own CNC equipment. This matters: no markups from external toolmakers, no weeks of waiting. Aluminum tooling is ideally suited for small and medium runs — noticeably cheaper than steel, faster to produce, and perfectly capable of delivering batches from tens up to several thousand parts.

Materials — from Standard Grades to Fiber-Reinforced and Heat-Resistant

We work with standard engineering thermoplastics: ABS, PP, PE, PA (nylon), PC, PC-ABS, and others. Material selection is driven by the part’s real operating conditions — mechanical load, temperature, chemical exposure, and appearance requirements.

For applications that demand extra stiffness or strength, we can also mold plastics reinforced with glass or carbon fiber — these runs are arranged individually. When heat resistance is critical, we turn to materials like PBT-GF20: finished parts consistently handle temperatures up to ~200 °C, which makes them suitable for service near heat sources — in automotive electrics or household appliances, for example.

Who It’s For

Our machine injects up to ~50 g per cycle and accepts molds up to 120 × 200 mm — the natural fit is small to medium parts: electronic enclosures, functional plastic components, fasteners, gears, knobs, caps, packaging, replacement components, and spare parts for equipment. Exactly the niche where large factories will not take runs under several thousand units, and one-off 3D printing is already too slow and too expensive.

Pricing is transparent — no hidden tooling markups. You know upfront what the prototype mold will cost, what the production mold will cost, and what the per-part price will be. Send us a 3D model (STEP, STL) or a description of the task, and we will size the run, recommend the material, and quote both stages.
