Resin / metal machining​ : improve a cutting process for a wide variety of materials

High transparency polycarbonate machining

A HIGH-QUALITY TRANSPARENT MODEL WOULD BE MANUFACTURED BY OUR UNIQUE HIGH TRANSPARENCY TREATMENT.
 
PC (polycarbonate) is a high-functional plastic, which is also called “super engineering plastic” among resins.
Its transparency is nearly in the same capacity as glass (a transparency coefficient of 85% to 90%), it has the highest heat resistance (equivalent to about 50 times that of acrylic resin). 
Depending on usage, it shows excellent heat resistance, ranging from 250 to 266℉.
 

♦Our strengths

Although transparent polycarbonate turns cloudy white after the cutting process, we have established our own unique process to return it to its original transparency using a unique process.
Therefore, we can provide polycarbonate prototypes with an excellent transparency and precision which do not require polishing at a low cost and a short delivery time.
In addition, we offer decorative elements, such as painting and plating on polycarbonate. 
 

♦Examples

  • Transparent external cases on mechanical equipment for flow analysis
  • Display models with a transparent external case for visualization of internal mechanical components
  • Tutorial and educational purpose models.
  • Lens parts for equipment such as headlight, tail light, etc.

High transparency acrylic machining without polishing

REPRODUCTION WITH HIGH-PRECISION DIMENSIONS WITHOUT POLISHING
 

■ Characteristics of acrylic (PMMA)

Acrylic resin is noted for its high degree of transparency (approximately 93%) which is more transparent than glass (approximately 90%).

It is well-suited when creating models that require intricate designs, such as a monument.

◆ Our strengths
We machine acrylic products using an end mill manufactured in collaboration with a top quality blade-making firm, ensuring precise cutting.

This method eliminates the necessity for manual polishing, which can diminish dimensional accuracy, resulting in high machining precision.

In particular, transparency can be reproduced even for detailed shapes such as lens cuts, leading to the possibility of producing outstanding lens cut models.

In addition, cutting processing is performed by the dry cutting method. Therefore, the adhesion of chemical substances contained in the cutting fluid can be minimized. 

♦Examples

  • Our work of “Variations of Time” exhibited at Milan International Furniture Fair [Milano Salone]
  • Experimental micro-channel flow models such as a microscope and a camera for observation of fluid flow channels
  • Exhibition models featuring design, including monuments
  • Lens parts for transport equipment such as headlight and tail light, etca top quality

Vacuum casting

3D PRINTING MODELS × VACUUM CASTING: ULTRA-SHORT DELIVERY TIME POSSIBLE.
 

By using a 3D printed model as a master model for the vacuum casting process, it is possible to deliver in the ultra-shortest time.

♦ Process overview

  1. A silicone rubber mold is made in a reversed shape of the master model using silicone rubber material.
  2. Liquid casting material is injected into the silicone rubber mold in a vacuum environment.
  3. Vacuum casting materials are cured and then taken out of the silicone rubber mold, and finally, made into finish products.

♦ Characteristics

  • Generally suitable for molding a small amounts (10-20 lots).
  • This method would be the best especially for experimental designs in the developmental process when quick delivery is required because the design might need to be modified. This can be easily done by modifying the shape of the master model.
  • Various types of casting materials often can be combined in a single mold.
  • Simultaneous multi-color casting is made possible by our unique method.

♦ Materials

ABS like (urethane based), PP like (urethane based), Acrylic like (epoxy based) and elastomer, etc.

In addition, toning, GF blending, and blending of light-diffusing agents are available. The hardness of the elastomer is adjustable.

STEP5: Quality Assurance and Precision Inspection

A quality inspection is performed. At INAC, where quality comes first, we use CMMs, gauges, and other equipment for precision checks.

STEP4: Post-Processing and Finishing

Finishing is done by removing the supports, polishing, and applying transparency treatment. It is also possible to paint and apply plating to the formed product.

STEP3: UV-Laser Print Formation (SLA Process)

Output: The product is formed by irradiating the liquid with a laser beam of UV light and laminating it. The conditions of the external environment, such as room temperature and humidity, must be maintained.

STEP2: Model Program Generation and Support Adjustment

A program for model formation is created. Depending on the shape, it may be necessary to adjust the degree of tilt and the position of the supports.

STEP1: CAD File Submission

Upload your CAD to our online quoting platform.

STEP 3: Rendering and Scene Integration

We can also handle exterior modeling and interior structure design based on illustrations. After creating the 3D models, we can create a rendering to fit a scene. We can deliver images even if we do not proceed with production.

STEP 2: Detailed Design and 3D Modeling

Once the design is determined, drawings and 3D models will be created. The structure will be examined, taking into consideration not only the external design but also functionalities such as mating and sliding.

STEP 1: Initial Design Consultation

The first step is a meeting to discuss the project. Drawings are not required for this meeting. We will create a design from a sketch based on the overall image and concept that you have in mind.

STEP5: Quality Assurance and Inspection

We perform quality inspections. At INAC, where quality comes first, we use CMMs, gauges, and other equipment for precision checks.

STEP4: Post-Casting Finishing

Vacuum casting materials are cured and then taken out of the silicone rubber mold. Then we perform finishing such as deburring and gating, and they are made into finish products.

STEP3:Material Injuction

Liquid casting material is injected into the silicone rubber mold in a vacuum environment.　

STEP2: Mold Preparation

The silicone mold is cut open into a male and female mold, and the master model is removed.

STEP1: Mold Creation

The master model is fixed to a wooden frame and silicone is poured to create a mold.
