3D Printing Prototype
3D Printing is an additive manufacturing process that works best for rapid prototyping, complex designs, multipart assemblies and even functional, end-use parts. Choose from SLA(Stereolithography ) for photosensitive resin parts,PolyJet used for a variety of simulating overmolds, Selective Laser Sintering (SLS) for industrial-grade nylon components and Direct Metal Laser Sintering (DMLS) for fully dense metal production.
SLA(Stereolithography)is a great choice for complex prototype geometries because of the precision to which it builds and the ability to apply a multitude of finishes. Jevny’s expert finishers also make Stereolithography (SLA) a wonderful medium for your sales and marketing needs. We can handle full assembly models for photo shoots to focus group samples and everything in-between.
SLS (Stereo Laser Sintering)is one of our most versatile and cost-effective 3D printing technologies.Made from durable white nylon, SLS parts are typically used for concept models, fully-functional prototypes and first article production pieces.SLS parts have a slightly grainy matte finish, but retain high dimensional accuracy and detail.
PolyJet 3D printing is our fastest and most precise 3D printing option. The technology is well-suited for creating production-like prototypes in a wide variety of materials, including rubber-like and translucent components. It can also print in multiple materials, which is often used for simulating overmolds.
DMLS（Direct Metal Laser Sintering）is an additive manufacturing technique that uses a Ytterbiu fibre laser fired into a bed of powdered metal, aiming the laser automatically at points in space defined by a 3D model, melting or rather, welding the material together to create a solid structure.
Clear Plastic Machining Prototype
Many applications benefit from using clear machined parts to help view the process or improve aesthetics. Including automotive lighting and lamps, lightpipes and displays all require good optical components characteristics.
Acrylic machining and Vacuum casting techniques can produce clear prototype. Factors that determine the optimal solution include the degree of clarity required, part complexity, quantity and timescales.Acrylic polishing requires the removal of material and it is essential to achieve a good machined finish before polishing to ensure critical dimensions can be maintained. Manual polishing requires different grades of polishing process used in conjunction with polishing paste which will remove surface material and leave high quality polished finish on CNC acrylic and other plastics.Jevny employs skilled craftsman with many years of experience in this highly specialized process.
Vapor polishing is ideally suited to the polishing polycarbonate of small features and offers improvements to internal and external surface finishes. Minor scratches and other small surface irregularities can be removed from machining polycarbonate parts by vapor polishing. The process is performed with a chemical vapor, which attacks the surface of the plastic and smoothes it. When done properly, vapor polishing can provide optical quality finishes.
PU Casting/RIM/Silicone Rubber
Polyurethane casting is ideal for applications that require quantities ranging from one to hundreds of parts, avoiding the expense of a machined injection mold. Because this process is inexpensive (compared to traditional injection molding), time and money are saved when changes in design are required during product development. Since our molds are flexible, difficult geometries such as undercuts or draft can be produced easily, which allows us to build parts that cannot be manufactured elsewhere.
RIM (Reaction Injection Molding) process uses polyurethanes to produce molded parts. The polyurethanes begin as two liquid components, compared with the pellet form of most thermoplastics. These liquid components - an isocyanate and a polyol - are developed in two-part formulations, which are often called polyurethane RIM systems.Compared to Plastic Injection Molding, rapid injection molding is a more simple and convenient process with a shorter production cycle.
Liquid Silicone Rubber(LSR) Jevny is the professional manufacturer of Mould Making Silicone Rubber, Condensation Silcone Rubber, Addition Silicone Rubber , Life Casting Silicone Rubber , Silicone Leather etc.Also We can provides a serial services of silicone such as molding, insoles, sexy dolls, electronics, relative silicone materials and latest developed products, etc.Liquid Silicone Rubber molding has thousands of applications across a variety of industries, including medical, automotive, infant care, general industrial markets, aerospace, electronics and many other specialized industries.
