Plastic Product Prototype Development Services


Stebro Mold is a plastic parts injection molding manufacturer. from prototype to the final product. We provide product design and rapid prototyping, rapid tooling, and low-volume manufacturing services to support your product development needs at a competitive price. T

hese services including custom CNC manufacturing, CNC prototype machining, CNC aluminum prototype, CNC plastic prototype, SLA plastic prototype, SLS plastic prototype, Vacuum Casting, rapid tooling, and Injection molding.

While each provides its benefits, knowing the inner workings of the technology, compatible materials, and typical applications will help you decide which rapid manufacturing technique is best suited for your plastic projects.

Different from other product design and prototyping companies, we also provide valuable advice for optimizing your plastic part design to lower the prototype cost as well as tooling and molding cost in mass production.

What is Rapid Prototyping?

Rapid prototyping involves a group of manufacturing techniques that utilize 3D systems to fabricate high-quality physical products quickly. Without building a mold, rapid prototyping creates parts in a much quicker time frame and at lower prices, saving clients’ money and time. Rapid prototyping is used to produce plastic prototypes and metal prototypes, which allows your product designers to closely simulate the final product appearance and function, and also reflect the validity of the physical dimension and the ease or complexity assembly work, and yet give them space to modify and optimize the design.

SLA 3D Printing and SLS 3D Printing

SLA 3D Printing and SLS are two widely used 3D printing technologies for plastic parts.

CNC Machining Services, Machined parts and Project Prototypes in as fast as 24 hours

CNC machining processes is a widely-used manufacturing process for plastic and metals. We provide various types of CNC machining services with a fast and cost-effective method for producing high quality for metal and plastic parts no matter what your demands or requirements are.

CNC Plastic Machining Prototype Services

In CNC plastic prototype machining, the part is manufactured by machining in the mass of a plastic block by CNC milling machines. In the process of CNC machining, heat will be generated, that would put the effect on the characteristic of plastics. In order to get qualified machined plastic parts, the first important is to use semi-finished products treated with internal stresses, the heat generated during machining process will lead to the release of internal stress, which results in deformation parts. For materials with high water absorption (such as nylon), dehumidification is needed before processing. The tolerance of plastic is bigger than metal, also plastic thermal expansion coefficient is much larger than the metal. So when machining plastics, these two factors must be taken into account.

Advantages of prototype CNC plastic machining:

  • Wide selection of the material for the plastic CNC prototype. Direct use of engineering plastic material such as ABS, PP, POM, PEEK, PC, PPS, PA and PMMA. The mechanical properties close to the injected part.
  • Wide range of CNC plastic prototype surfaces. After the CNC machining, we have to do polish to remove the rough edges and burrs. It is also possible to do high gloss polish, painting, printing, sandblasting and chrome plating on the surface.
  • The general tolerance for the CNC Plastic Prototype is ISO DIN 2768M for plastics.
  • CNC machining offers more potential for threads and undercuts

In conclusion, plastic CNC machining is suitable for unit production in the context of dimensional accuracy, surface finishes, and functional testing. When one big or complex parts is in need of CNC milling prototype. We will consider it to be split and glued together to reduce the manufacturing cost. 

CNC Metal Machining Services

In addition to plastic CNC machining services, we also offer customer CNC Metal machining services. The material can be Aluminum, Stainless Steel and brass.

Vacuum Casting

Vacuum Casting is a copying technique used for the production of small series of functional plastic parts. Using two-component polyurethanes and silicone molds, Vacuum Casting is known for its fast production of high-quality prototypes or end-use products. Silicone molding results in high-quality parts comparable to injection-molded components. This makes vacuum casted models especially suitable for fit and function testing, marketing purposes or a series of final parts in limited quantities. Vacuum Casting also lends itself well to a variety of finishing degrees, and we can match the finish you need for your parts.
