FAQ
Frequently asked questions about injection molding, prototypes, 3D printing and our filament shop.
We process the full spectrum of engineering thermoplastics: Standard (ABS, PP, PE, PS, PMMA), Engineering (PA6, PA66, POM, PC, PBT, PET, PPE), High-Performance (PPS, PEEK, PEI, LCP, PSU) as well as elastomers like TPU, TPE and PEBAX. Plus COC and COP for optical applications.
We deliver simple injection molding prototypes from 48 hours after order confirmation. For more complex geometries or small batch projects allow 3–5 business days. 3D printed parts (FDM) are often available even faster.
The first conversation (30 minutes, by email or video) is free of charge. More extensive consulting projects are billed by time in CHF/hour. You always receive a clear cost overview before the start.
We accept STEP (.stp, .step), STL, IGES and PDF drawings. For precise dimensions we recommend STEP + PDF drawing. Max. 20 MB per file.
FDM (Fused Deposition Modeling) processes thermoplastic filaments layer by layer. Advantages: affordable, large parts, many materials. SLA/DLP uses photopolymer resins cured by UV. Advantages: high precision (±0.05 mm), smooth surfaces, ideal for medical devices and optics.
As a rule of thumb: from around 500–1000 parts (depending on geometry and material) a steel tool pays off. For prototypes and small batches up to 500 pieces, additively manufactured precision tools are the more economical choice.
Yes — process optimization and defect analysis on existing injection molding processes is a core service. Remote consulting by video and photo is often possible. For complex cases we also come on site.
Yes, of course. We treat all project documents confidentially and sign an NDA on request before the first exchange.
Standard wall thicknesses are 1.0–4.0 mm depending on material. Too thin walls (< 0.5 mm) can cause filling problems, too thick walls (> 6 mm) sink marks. We advise you on wall-thickness optimized design.
Instead of expensive steel tools, injection molds are manufactured by additive processes (SLA/DLP or FDM with engineering resins). This drastically reduces costs and lead times — from weeks to hours. Tool life: up to 500 parts, sufficient for prototypes and small batches.
Yes — we deliver to the EU and worldwide. For consulting services we also work remotely. Please note the respective customs regulations for filament orders.
Our team holds qualifications as certified plastics technologist and plastics specialist. We have experience with ISO-compliant quality assurance and FDA requirements for Medtech materials.
Consulting services and prototypes are paid by invoice (payment term 30 days net). Shop orders by credit card, Twint or prepayment. For first orders we reserve the right to require prepayment.
For prototypes: from 1 part. For the filament shop: no minimum order quantity. For large quantities and special orders please contact us directly.
In our filament shop you find our own SwissInjection niche filaments such as COC, COP, PEBAX and TPU (from July 2026). Pre-orders and registrations are possible.
The filament shop opens in July 2026. Until then pre-orders and registrations for 10% introductory discount are possible.
We compare China Standard, China Premium, Swiss Made Medium and Swiss Made Premium. Decisive factors are cost, risk, precision, lead time and communication needs.
Yes. Sampling, process optimization and FAI documentation can be booked independently of a tooling project.
Project requests support up to 5 files with maximum 50 MB per file. Suitable are STEP, STL, IGES, 3MF, OBJ, PDF, Office files, images and ZIP archives.
We support German, French, English and Spanish. The contact form and chat take the preferred language into account.
Yes. For clearly defined consulting, prototyping, tooling and sampling projects we create fixed-price offers with defined scope.
