5-star reviews

I can definitely recommend this company! Very good quality of prints, and materials. Communication with the customer, willing to help and find the best solution on a truly professional level.

Ich war von Rubens Arbeit positiv überrascht. Er hat unsere unsere Erwartungen Unser Ingenieur gab ihm lediglich eine schematische Darstellung, woraufhin er eine maßstabsgetreue, automatisierte Schweißwalze konstruierte. Leider war die Fortführung die Schweißprojekts aufgrund einer Umstrukturierung in unserem Unternehmen nicht möglich.

They responded promptly to my request, providing the necessary details, and the printed items turned out very well. I am very pleased with the way the collaboration went. I highly recommend!

Super collaboration, they helped me even more. Fast processing and delivery. Piece without problems, according to the model. I highly recommend.

Very relaxing to work with someone who cares to understand the client's need and strive for the highest quality. I have had two atypical jobs and both were done from design to print flawlessly.

THIS IS Plastic Mold Design?

A well-designed mold reduces scrap, shortens the injection cycle, and extends the tool's service life. We work with complex geometries—inserts, cooling channels, draft angles—and deliver the complete STEP file, ready for CNC production.

Before moving to the mold, we validate the design through 3D prototyping—this way, you invest in the mold only after the part has been approved.

What we deliver:

Complete STEP file — cavity, punch, injection system, cooling channels, inserts.
DFM Analysis — draft angle, wall thickness, shrinkage areas, and filling issues.
Prototyping for validation using FDM, SLA, or SLS prior to the start of CNC production.

What you can send us:

STL, STEP, IGES, OBJ, 3MF, DXF, DWG, or ZIP (up to 200 MB). If you don’t have a 3D file, we’ll start with a sketch or a physical part. Confidentiality agreements are available upon request.

Why companies choose Capib.ro for mold design:

Real-world experience in designing products optimized for injection molding—we don't just draw; we understand the manufacturing process.
A STEP file ready for CNC machining, with no further modifications required.
CAD design in SolidWorks and Onshape at 100 lei/hour — transparent and predictable.
Compatible with any injection molding material: PP, ABS, PA6, PA12, PC, POM, TPE, and others.
Free consultation — a response within 2 hours on WhatsApp.

Questions frequent

Want to you put a question?
Answer — within 2 hours, or, for complex projects, within 24 hours

What is plastic mold design, and when do I need it?+

Plastic mold design is the process of CAD modeling the cavity and the injection system for mass production via injection molding. It is necessary when production runs exceed 500–1,000 units and the per-unit cost of 3D printing becomes higher than the payback period for the mold.

What do you deliver at the end of a mold design project?+

We deliver the complete STEP file for the mold, ready for production—including the cavity, punch, injection system, cooling channels, and inserts. The file can be sent directly to a mold manufacturer without any further modifications.

Do you also create a prototype of the part before designing the mold?+

Yes—we recommend validating the design through 3D printing before investing in a mold. We produce functional prototypes using FDM, SLA, or SLS for testing, so that the mold is designed based on a design that has already been validated.

What software do you use for mold design?+

We use Onshape and SolidWorks—professional engineering CAD software, ideal for dimensional accuracy, tight tolerances, and generating STEP files compatible with any mold manufacturer.

How much does it cost to design a plastic mold?+

The price depends on the part's complexity, the number of cavities, and the injection molding system chosen. CAD design is priced at 100 lei per hour. We provide a customized quote after analyzing your part—no phone calls required.

How long does it take to design a mold?+

A simple mold can be designed in 2–5 business days. Complex designs with multiple cavities, conformal cooling channels, or inserts may take 1–3 weeks. We will confirm the exact lead time after evaluating the design.

Do you also provide a design for manufacturability (DFM) analysis for the part?+

Yes—we check the draft angle, wall thickness, areas prone to shrinkage, and potential filling issues before we begin designing the mold. This step reduces the cost of subsequent modifications.

Can you design multi-cavity molds?+

Yes, we design molds with one or more cavities, depending on the production volume and the available injection molding equipment. Multiple cavities reduce the cost per part in mass production.

What types of plastics can be molded using the designed mold?+

We design molds compatible with standard injection molding materials: PP, PE, ABS, PA6, PA12, PC, POM, TPE, and others. The choice of material influences the design of the cooling channels and the shrinkage tolerances.

Can I use the STEP file with any mold manufacturer?+

Yes—the STEP file is the universal format accepted by all mold manufacturers and CNC milling centers. We deliver the file optimized and ready for production, without the need for another engineer to intervene.

Do you also offer mold manufacturing, or just design?+

Capib.ro specializes in CAD design of molds and validation through 3D prototyping. For the physical production of the mold, we collaborate with partners who specialize in CNC milling—we can coordinate the entire process upon request.

Why should I choose Capib for plastic mold design?+

We have real-world experience in designing products optimized for plastic injection molding—we don’t just draw the mold; we understand the manufacturing process. We combine professional CAD design in SolidWorks and Onshape, validation through 3D prototyping, and delivery of production-ready STEP files, at 100 lei/hour.
