Invisible braces (including transparent aligners and clear retainers) have
the advantages of being aesthetically pleasing, comfortable, easy to maintain,
easy to clean, having a short treatment cycle, and being convenient to put on
and take off. They are quickly becoming the preferred alternative to traditional
wire braces. In short, invisible braces are made by processing plastic sheets
through thermoforming on custom 3D-printed dental models.

1. Intraoral Scanning

Before manufacturing transparent dental aligners, the first step is to obtain
the patient's oral data. Usually, a 3D intraoral scanner is used to scan the
patient's mouth, or a desktop 3D scanner is used to scan physical models or
plaster models to obtain 3D digital model data in STL format.

2. Design

Import the scanned digital model files into appropriate orthodontic or dental
computer-aided design (CAD) software (such as 3Shape, Exocad). The design
software includes two main categories: making transparent aligners and making
clear retainers.

Invisible Aligners

Dentists perform tooth separation, tooth arrangement, animation, and staging
based on the scanned data, communicate with clients to confirm the treatment
plan and schedule, and sometimes use CBCT data for assistance during the
planning stage.

After the treatment plan is finalized, the dental model data for each stage
is output.

Clear Retainers

Retainers are used in the post-treatment phase. To make retainers, only the
scanned dental model data after treatment is needed. Simple operations such as
trimming and filling undercuts are performed in the design software, and
finally, the dental model data is output.

Optional Designs for Dental Model Data

– Hollow Models

To save costs, dental models are usually designed to be hollow, with a wall
thickness generally ensuring no less than 3mm.

– Through Holes

Hollow models have cavities, which may lead to printing failures. It is
recommended to add through holes at the bottom.

– Honeycomb Filling

To reduce the decrease in overall strength of the hollowed model, honeycomb
structures can be used to fill the hollowed areas.

– Reinforcing Crossbars

To avoid shrinkage and deformation of arch-shaped dental models, crossbars
are added at the opening.

– Fixture Positioning

To match automatic invisible brace cutting machines, positioning holes need
to be added at the bottom of the dental model, with specific shapes referring to
the cutting machine.

– QR Codes

Adding QR codes to the dental model, which can be read by industrial cameras,
enables quick and accurate access to relevant information about the dental
model, realizing automatic identification of dental model information.

– Text Markings

Adding concave or convex text markings on the dental model facilitates later
sorting work and greatly improves work efficiency.

3. 3D Printing

(1) Load the model in the slicing software. Thermoformed dental models are
generally printed directly on trays without supports. Then, select the resin and
parameters to complete slicing.

(2) Upload the sliced data to the printer and complete the printing.

4. Post-Processing of Dental Models

(1) Remove the dental model from the tray.

(2) Place the model in a cleaning machine filled with isopropyl alcohol (IPA,
≥96%) for cleaning. To ensure thorough cleaning, it is usually cleaned
twice.

(3) Take the model out of the IPA and air-dry it in a well-ventilated area at
room temperature or dry it with an air gun.

(4) Put the cleaned and dried model into a curing oven and set appropriate
parameters for post-curing.

5. Thermoforming

Using the printed model, process the sheets into invisible braces with dental
thermoforming equipment.

6. Laser Marking

Use laser marking on the sheets for easy classification, packaging, and
traceability.

7. Trimming

– Manual cutting

– Automatic trimming

8. Polishing

Cutting or trimming with scissors or dental handpieces can result in sharp
and rough edges. Use grinders and polishers to trim and polish the edges.

9. Quality Inspection

Quality inspection is a particularly important step in the manufacturing
process. The finished products need to be thoroughly inspected to ensure they
are clean and free of defects.

10. Packaging

Classify according to the client and their treatment cycle, and pack the
invisible braces into custom boxes.

A Quick Look at Iron Casting Basics

Iron casting is a process where molten iron is poured into a mold and cooled into a solid shape. This method has been used for hundreds of years because it can create complex parts with steady quality.

Today, you can find iron castings in engines, pumps, pipes, machine bases, and even home décor. As a buyer, learning the basics gives you a clear picture of how each type performs in real-world applications.

Why Choosing the Right Iron Casting Matters

Before you place an order, it’s important to know how the type of casting affects performance. The right choice can lower maintenance costs, improve safety, and extend product life.

Gray iron and ductile iron have different structures inside the metal, which leads to different mechanical properties. Let’s explore them step by step.

Gray Iron Casting: Affordable and Steady

Gray iron is one of the oldest and most common materials in foundry work. It gets its name from the gray color of its fracture surface.

Key advantages of gray iron casting:

• Excellent vibration damping, great for machine bases and frames

• Smooth surface finish that needs less machining

• Lower cost compared to other iron castings

Gray iron is best when you need steady performance at a reasonable price. It works well in applications where heavy strength is not the main goal, such as cookware, housings, or decorative items.

Ductile Iron Casting: Strong and Versatile

Ductile iron, also called nodular or spheroidal graphite iron, is a newer option that offers impressive strength. During production, magnesium is added to the molten iron, forming round graphite nodules inside the metal.

Key benefits of ductile iron casting:

• Higher tensile strength and toughness

• Good impact resistance, even in cold temperatures

• Long service life for demanding industrial uses

Ductile iron is often used in automotive parts, pipes under pressure, heavy-duty gears, and safety components where strength and flexibility are critical.

Comparing Mechanical Properties of Gray and Ductile Iron Castings

When you compare gray iron casting with ductile iron casting, you’ll see clear differences in strength, hardness, and elongation.

• Strength: Ductile iron has far higher tensile strength, often more than double that of gray iron.

• Hardness: Both can be adjusted through heat treatment, but ductile iron usually offers a better balance between hardness and toughness.

• Elongation: Ductile iron can stretch without breaking, while gray iron tends to be brittle.

This means ductile iron is safer for parts that must bear shocks or constant pressure. Gray iron, on the other hand, is perfect for stable bases and components where vibration control is key.

Cost and Production Considerations

Price always matters in procurement. Gray iron casting is less expensive because its production is simpler and faster. Ductile iron casting costs more due to extra steps, such as adding magnesium and controlling cooling speed.

However, ductile iron’s longer lifespan and strength can reduce replacement costs over time. Buyers should weigh the upfront price against long-term savings before making a decision.

When to Choose Each Type of Iron Casting

Picking between gray and ductile iron depends on your project goals.

Choose gray iron if you need a cost-effective material with good vibration damping, such as for housings, benches, or cookware.

Select ductile iron if your parts will face heavy stress, like pumps, valves, truck axles, or pipelines.

Think about the environment, load, and safety standards of your final product. Talking with a trusted supplier can also help you match the right material to your design.

Tips for Buyers Sourcing Iron Castings

1. Check supplier experience. Look for foundries that specialize in either gray or ductile iron.

2. Review quality records. Ask for inspection reports, tensile tests, and surface finish samples.

3. Request prototypes. Testing a sample can confirm that the casting meets your strength and size needs.

4. Plan for lead time. Ductile iron may take longer to produce, so include extra time in your schedule.

A careful sourcing process helps you avoid delays and ensures you get castings that meet global standards.
