Prototyping with
Simple Injection Molding Service

What We Offer

Prototyping with Simple Injection Molding service utilizes aluminum molds that offer a streamlined approach to creating prototypes and transitioning smoothly to medium-scale production. This method is not only faster but also more cost-effective compared to traditional molding techniques.

At INAC US, we understand that flexibility and efficiency are crucial when developing new products. That’s why our simple injection molding service is designed to handle frequent design modifications and quick turnarounds, making it ideal for producing a variety of small to medium quantities.

Whether you’re in the initial stages of prototyping or ready to scale up, our aluminum molds, crafted from precise 3D data used during prototyping, ensure a seamless transition to mass production without the need for extensive rearrangements.

Choose INAC US for your prototyping needs and experience the advantage of our simple injection molding service today.

vs. Other Processing Methods

vs. CNC Machining

Advantages of simple injection molding:

  • Economical for large volumes as the same mold can be used repeatedly.
  • Offers high repeatability and good surface finish.
  • Allows for the use of a wide range of materials.

Disadvantages of simple injection molding:

  • Initial costs are high due to the need for mold creation.
  • Not ideal for design changes as each change requires a new mold.
  • Longer lead times compared to CNC Machining.

vs. Turning/Lathing

Advantages of simple injection molding:

  • More cost-effective for large volumes compared to 3D printing.
  • Better surface finish and precision.
  • Supports a wider range of materials.

Disadvantages of simple injection molding:

  • Not as quick for producing single prototypes.
  • Less flexible for design changes compared to 3D printing.
  • Requires molds, which can be expensive and time-consuming to create.

vs. 3D Printing

Advantages of simple injection molding:

  • More suitable for large-scale production due to mold reusability.
  • Produces parts with consistent quality and good surface finish.
  • Can handle a wide range of materials.

Disadvantages of simple injection molding:

  • Less ideal for one-off prototypes or low volumes.
  • Design alterations require new molds.
  • Longer set-up times compared to lathe processing.

vs. Vacuum Casting

Advantages of simple injection molding:

  • Provides better accuracy and repeatability.
  • More suitable for large production runs.
  • Can accommodate a wider range of materials.

Disadvantages of simple injection molding:

  • Higher initial costs due to mold creation.
  • Less flexible for design changes compared to vacuum casting.
  • Not as quick for producing single prototypes.

FAQs

8.27 x 11.69 x 2.36 inches

Materials containing pellet material can basically be injection molded.
Please consult with us for materials containing glass or fibers. Molding with supplied materials is also possible.

The following factors affect cost: material, form, dimensional accuracy, finish level, delivery date, quantity.

We can accept solid 3D CAD models in IGES (.igs), STEP (.stp) or PARASOLID(.x_t).

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.
