Servizi di stampaggio ad iniezione assistita da gas

Services from TOPS Precision’s Gas-Assisted Injection Molding provide robust and lightweight plastic components with improved structural properties. The advanced molding method utilizes high-pressure gas to make hollows inside plastic parts in order to save material and improve structural strength.

Engineers and designers work together in TOPS Precision to design gas-assisted injection molding processes for both prototypes and manufacturing. Our gas-assisted injection molding machines have great control over gas pressure, materiali, and part quality in the molding process.

The advanced gas-assisted injection molding provides improvements in terms of increased structural strength, decreased wastage, and better manufacturing performance, either for lightweight structural parts or improved surface finish.

Salient Features of Our Gas-Assisted Injection Molding Services

These capabilities will enable gas-assisted injection molding to be an efficient method for creating lightweight and strong components:

1. Less Use of Plastic Material

Using gas-assisted injection molding will result in a lower amount of plastic used to fill the cavity in the mold. The material used will be less compared to other processes, but at the same time, the part will remain strong enough.

2. Better Surface Finish

The process of controlling the gas pressure ensures that the plastic material remains firmly held within the mold cavity. Di conseguenza, a high-quality external appearance is ensured, thus avoiding the need for any secondary finishing.

3. Fewer Sink Marks

A sink mark can appear in a plastic part because of different rates of cooling. Using gas-assisted molding, the internal pressure of gas ensures that the material solidifies from the inside, hence no occurrence of sink marks.

4. Light and Strong Components

A hollowed core is achieved in the process, which makes the component light in weight while maintaining its strength. A lighter component increases efficiency while reducing its load-bearing capacity.

What is Gas-Assisted Injection Molding?

Gas-assisted injection molding refers to an advanced plastic forming process where high-pressure gas is injected into the heated plastic material to create a hollow core inside it, allowing the plastic to flow uniformly. The final product is made up of lightweight yet robust plastic with a stable shape after cooling.

This manufacturing process is recommended for the production of thick plastic components because the gas assists in creating light and strong components.

Some common items made using gas-assisted injection molding include:

Car interior panel
Furniture parts
Household appliance case
Parts for industrial machines
Electronics casing
Plastic structure

The method enables the production of durable products at relatively low costs by minimizing waste material.

How Does Our Gas-Assisted Injection Molding Process Work?

TOPS Precision follows a standardized procedure in gas-assisted injection molding manufacturing processes to ensure quality control of both gas and products. The manufacturing process is continuously monitored to achieve a uniform wall thickness of the produced component.

1. Design and Mold Preparation

The process begins with design planning, where we ensure gas channel location as well as the melt flow path. It is important to evaluate the part shape and its thickness to ensure gas flow. Preparations of the mold for the injection process are essential.

2. Material Injection Process

The first step involves the injection of the molten plastic material into the mold. Qui, we aim to partially fill the part's shape to create its skin. There will be empty spaces for the gas channels during this process.

3. Gas Injection Stage

Following partial filling, gas is injected into the superheated material using channels. In turn, the gas pushes away the material and results in the creation of internally hollow parts. Così, it saves us material, yet retains strength in our products.

4. Raffreddamento e solidificazione

After gas distribution, the component is cooled down. Even cooling helps prevent warping. Così, cooling and stabilization become an important process in achieving strength in our products.

5. Finishing and Quality Inspection

Dopo il raffreddamento, the part is cut, and other finishing operations may be done. Our products will then be tested based on wall thickness, finitura superficiale, and mechanical properties. Only quality products are dispatched.

Properties of Gas-Assisted Injection Molded Components

Gas-assisted molded parts are strong, leggero, and possess good surface quality. The presence of air inside makes the parts tough, but at the same time, cuts down on material costs. Quindi, these parts are best suited for use both structurally and cosmetically.

Advanced Gas-Assisted Injection Molding Techniques

Our company utilizes advanced gas-assisted injection molding techniques to improve production efficiency. These techniques provide better materials flow, Qualità della superficie, and stiffness of parts. Advanced processing technology guarantees repeatable results.

1. Shot-Shot Gas Injection Technique

Shot-shot gas injection technique refers to the injection of the gas into the partially filled mold. This helps to move the melt into the mold using gas pressure. Da questa parte, uniform walls can be obtained with minimum material.

2. Full-Shot Gas Injection Technique

Full-shot gas injection technique means the injection of material until the mold gets filled under pressure. Then the gas penetrates the hollow areas within the part. This helps to increase its strength and reduce stress.

3. Sequential Gas Injection Technique

With the sequential gas injection technique, a proper time frame is used to perform gas injection. Such a technique allows for improving cavity formation precision and shape consistency.

4. Temperature-Controllable Processing

Precise temperature control during injection molding helps to improve material flow and evenness of gas penetration. Warpage and shrinkage can be minimized in this way.
