How the Jiggering Process Works
Overview of the Jiggering Process
The jiggering process is a cool way to shape glass. It’s often used to make round things like plates and bowls. Soft glass is placed on a spinning mold during this process. As the mold turns, a tool called a jigger shapes the glass into the right form.
This method makes sure all items are the same size and thickness. This is important for how they look and work. Unlike blowing or pressing, jiggering focuses on being exact and wasting less material. Sometimes, people call this process “jollying,” especially when shaping ceramics or glass.
Machinery and Tools Used
Machines in the jiggering process are built for accuracy and speed. These machines have special features to do different tasks. For example, they use electric motors for smooth spinning and tools to adjust speed precisely.
Here’s a simple table of key features:
Measurement Type | Specification |
|---|---|
Working Widths | |
Mechanical Speeds | 98 to 492 ft/min |
Roll Batch Diameter | 12 to 55 in |
Drive System | Two separate electric motors |
Speed Adjustment | High-resolution encoder |
Tension Control | Real-time measurement via load cell |
Washing and Rinsing | Countercurrent washing method |
These machines also use molds and shaping tools to make items uniform. The mold gives the basic shape, and the jigger arm presses to refine it. Together, they make sure the process creates the same results every time.
Step-by-Step Explanation
Knowing the steps of the jiggering process shows how precise it is. Here’s how it works:
Preparation of Materials: Start with soft glass, either as a sheet or lump. It must be clean and pure.
Placement on the Mold: Put the glass on a spinning mold. The mold’s shape decides the product’s design.
Shaping with the Jigger Arm: While the mold spins, the jigger arm presses the glass. It moves carefully to shape the glass evenly.
Refinement and Smoothing: The jigger arm smooths and evens out the glass. This step ensures the thickness is the same everywhere.
Drying and Finishing: After shaping, the item is taken off the mold. It is dried and finished to make it stronger and look better.
This process makes sure every item is high quality. It’s fast, wastes less material, and is good for the environment.
Materials Used in Jiggering
The materials used in the jiggering process are very important. They affect how strong, even, and nice the glass looks. Let’s look at the main materials:
1. Glass Blanks or Soft Glass
Soft glass is the main material for jiggering. It comes as sheets or lumps. The glass must be clean, without dirt or bubbles. It also needs to be warm enough to shape. Soft glass is easy to mold and keeps its shape after cooling.
Tip: Check for cracks or bubbles before starting. This avoids flaws in the final product.
2. Molds
Molds give the glass its basic shape. They are made from:
Plaster of Paris: Good for short-term use.
Metal (e.g., Steel or Aluminum): Strong and lasts a long time.
Ceramic: Works well in high heat.
Each type of mold has special uses. Metal molds are great for making many items. Plaster molds are better for detailed designs.
3. Lubricants and Release Agents
Lubricants stop the glass from sticking to the mold. They create a thin layer between the glass and mold. Common ones include:
Graphite powder
Silicone sprays
Special oils
The right lubricant helps remove the glass without breaking it.
4. Shaping Tools
Shaping tools refine the glass. These tools are made from:
Metal: Strong and precise.
Wood: Good for gentle shaping.
Plastic or Rubber: Best for soft finishes.
Each tool has a job, like smoothing edges or making the glass even.
5. Cooling and Drying Materials
After shaping, the glass must cool and dry. Cooling racks or drying chambers help keep its shape. Some factories use special rooms to speed up drying.
Note: Cooling must be done carefully. Cooling too fast can crack the glass. Uneven cooling can change its shape.
6. Finishing Materials
Finishing materials make the glass look better and last longer. These include:
Polishes for smooth surfaces.
Coatings to stop scratches.
Paints or glazes for decoration.
These materials improve the glass’s look and add value.
Summary Table of Materials
Material Type | Examples | Purpose |
|---|---|---|
Glass Blanks | Soft glass sheets or lumps | Base material for shaping |
Molds | Plaster, metal, ceramic | Provides the initial shape |
