good design ≠ great design

Integration of great product appearance in ideal form factor with perfect functionality and ergonomics,
as-simple-as-possible tool design and issue-free manufacturability equals to great design

we hear you

Bring on the requirements - we solve the realization.
Excellent and smooth, direct communication. Responsive customer support.

focused and efficient

Design and engineering specialists in their own right - product development, mold-flow simulation, prototyping, in-house molding and tool shop, waterproofing, production and more -
form an efficient skill pool to get your custom made products up and running in surprisingly short time.

flexible approach

No matter how it starts, we get things running:

- modification of existing designs. We work together from any standard product but change size, add features, branding etc.
- completely different case, form factor, combination of features, branding, IML etc., bring your ideas and we develop for you.
- injection tool production starting from the 3D file of the part or delivered 2D / 3D sketches of finished tool designs.

Affordable through smart design

Plastic injection molds are high temperature, high pressure and high precision tools.
Therefore only high end quality steel material should be used and we are absolutely strict about this.
So mold costs depend basically only on 2 factors:

Mold Size

How big is the mold?

Well, this depends of course on your design.
Smart part design could reduce tooling costs.
For example complex or oddly shaped parts could be broken down to sub assemblies of smaller parts, if possible combined in one mold.

Can different parts be made in the same mold?

Yes, but
- part's plastic volume should not be too different
- must be of course the same material
- moving parts for undercuts must fit in

How many parts in one mold (Multi-Cavity)

Producing many parts in one production cycle (closing and opening of the tool) is very cost effective, but bigger molds are more expensive.
We calculate the ideal most cost effective numbers of cavities for each tool.

Mold size vs. Break-even quantity

Mold investments pay-off over quantity. A multi-cavity mold is more expensive, but production costs are significantly lower than a single cavity mold with a higher cost efficiency with respect to machine costs, energy costs, labor costs and other related factors.

Special Features

Moving inserts to produce undercuts?

It is possible and usual to produce certain features located at part sides or to create undercuts with moving parts inside the mold (slider).
It is also possible to design interchangeable inserts to produce different part versions with one mold.

Threads?

Plastic screws and threads are usual. Threads require special inserts with rotate and move upon opening and closing of the mold.

Mold-in metal parts?

Mold-in metal parts, like screw threads, magnets etc. can be mold in during the injection process and reduce assembly cost and time.

Multi-material / color overmolding?

Overmolding is a multi-shot injection molding process which produces a single end product from two or more different thermoplastics.
Used very often to ruggadize parts or add better grip with a rubbery elastomere over a rigid core (example: case handle)
A great way to create strong, functional, and aesthetically pleasing parts that won’t separate over time.
Works very well with low-production runs.

Two-shot injection molding?

Look at your toothbrush. It is certainly made with double injection of widely different materials (hard / elastic) in one production cycle.
Special machines with rotating tools make this possible. If you think about employing similar attributes, ask us. We show you how to do it.
Ideal for larger production runs.

IML?

In-Mold labeling is a modern way to integrate graphic features, similar to sticker or print, directly during the production cycle on your part. Interesting?
Check out more IML information here.

Break-even Quantity

Initial mold cost investments pay off over produced quantities.
Depending on the size and value of the parts produced,
mold costs pay-off after 10,000 to 50,000 units -
with the benefit of a highly individualized custom part or case.
Reduced assembly and branding costs are additional benefits.

Affordable through cost transparency

We pro-actively support your part design to identify potential cost reduction options with respect to mold design and production costs and deliver transparent calculations and cost breakdowns.
Hassle-free, reliable, predictable.

Expertise and Accuracy: The red line leading to predictable and beautiful results

Ideas are unique expressions of creativity and invention. Different. Individual.
Examples of custom products can only show a small slice of our scope.
We picked a few products which show interesting applications:

Examples of Custom Products

DriBiz - Innovative Dry Solutions (USA) ▼

DriBiz manufactures and markets unique dry solutions for shaving razors, hearing aids and smartphones.
DriBlade keeps your razor sharp and smooth over 3x times longer than air-drying.
DriSonic keeps your hearing aids dry and sounding great. Its simple and effective design provides quality storage for all popular mini hearing aids.
Used is a unique DriPacket silica technology to offset oxidation and germ build-up, and comes as a secure unit with locking clasp for easy travel.

We designed and produce for DriBiz the case and two blister inserts, for the DriBlade shaver box and the DriSonic hearing aid box.
The case features a long locking clip and a silicone gasket.
Branding on the top and back was accomplished with hot-foil printing

Ørgreen Optics - High-end Design Eyewear (DENMARK) ▼

Ørgreen Optics is famous for high-end Danish design eyewear, handcrafted in Japan.

We designed and produce for Ørgreen Optics their spare part box.
The PP case features additionally a printed reference card.
Branding with the Ørgreen logo on the lid. The case surface is matte but still very scratch resistant.

ByField Optics - Polarized Binoculars (AUSTRALIA) ▼

ByField Optics is an Australian-owned company specialized in custom-made eye protection for the military. Their products incorporate maximum strength UV lenses that are certified to ANSI Z87 1-2003 and US MIL DTL 43511D ballistic protocols.

We designed and produce for ByField Optics two different carrying cases for their line of polarized binoculars.
Additionally we produced branding on case lid with the ByField logo and black overprinting.
The case features an anti-reflective coating for military applications.

Loupe System - A Macro Lens for the Eye (HONG KONG) ▼

The best optical quality ever made available in a hand-held loupe.
Loupe Systems supplies watchmakers, jewelers and anyone looking for highest quality hand held magnification.
The Loupe System is the official loupe of the Grand Prix d'Horlogerie de Genève.

We supply the waterproof carrying case for all Loupe system kits and acessories.

Together with Loupe Systems we designed the Loupe Clip.
It features two different materials, produced in an overmolding process.

The custom made Hard Case protects the Loupe perfectly.
Polycarbonate / ABS material provides excellent stability, low weight,
and perfect surface - a high quality case for a high quality product.
A knurled silicone feature adds comfort and grip functionality to the design.
Both case parts and the silicone grips were produced separately and then subsequently assembled.
