Our Vacuum Forming Process
At BLG, our vacuum forming plastic process is designed to produce high-quality, durable components for a variety of industries. We work with materials such as PC, ABS, PVC, PS, PET, and more, using advanced blister forming machines. The process involves heating the plastic sheet, forming it to match the mold under vacuum, cooling, and precisely trimming it on a punching machine.
Our team also performs additional finishing steps, including folding, punching, and assembly, to deliver fully functional components. Businesses across North America trust us as a leading plastic supplier for custom plastic forming in Canada, the USA, and the EU, and as a provider of composite material for commercial vehicles that meets strict industry standards.

Step-by-Step Vacuum Forming Process
Here’s what the process looks like from start to finish
Step 1: Heating the Plastic Sheet
The process begins with a flat thermoplastic sheet, typically made from materials such as ABS, PC, PVC, PS, or PET. The sheet is clamped into place and gradually heated until it reaches its forming temperature. At this point, the material becomes soft and pliable but does not melt.
Controlling the heating stage is critical – uneven heating can cause warping or weak spots in the final part.
Step 2: Applying the Vacuum
Once the sheet is properly heated, it is lowered over a pre-made mold. A vacuum pump is then used to remove the air between the sheet and the mold, pulling the softened material tightly against every contour.
This ensures accurate replication of the mold’s details.
The precision of this step directly impacts the quality, strength, and dimensional accuracy of the final component.
Step 3: Cooling & Trimming
After forming, the plastic must cool and harden to maintain its new shape.
Cooling is controlled to prevent shrinkage or deformation.
Once the part has cooled, it is carefully trimmed using CNC cutting or punching machines to remove excess material and achieve the final dimensions.
This trimming stage is where tolerances are refined to meet exact specifications.
Step 4: Finishing & Assembly
Depending on the application, additional finishing steps are performed to prepare the component for use.
This may include:
- Folding or bending for structural strength
- Drilling or punching holes for fasteners
- Painting or coating for durability and appearance
- Bonding or assembly with secondary parts
Step 5: Quality Inspection & Delivery
Before components leave our facility, they undergo strict quality control checks. Dimensions, surface finish, and overall durability are verified against customer requirements and industry standards.
Only parts that meet specifications move forward for packaging and delivery.
This final step ensures customers receive reliable, high-performance components they can integrate with confidence.
Vacuum Forming vs. Injection Molding – What’s the Difference?
| Feature | Vacuum Forming | Injection Molding |
|---|---|---|
| Tooling Cost | Lower upfront cost (affordable molds) | High tooling cost (expensive steel/aluminum molds) |
| Lead Time | Faster setup, ideal for prototypes and small runs | Longer setup, best for large production volumes |
| Part Detail | Moderate detail, good for large/simple parts | High precision, complex geometries possible |
| Production Volume | Best for low-to-medium quantities | Cost-effective at very high volumes |
| Material Use | Uses plastic sheets (less material waste) | Uses pellets, more control over material properties |
| Applications | Panels, covers, housings, trays | High-volume consumer goods, automotive parts |
Vacuum Forming vs. Thermoforming – What’s the Difference?
| Feature | Vacuum Forming | Thermoforming |
|---|---|---|
| Definition | Uses vacuum pressure to pull heated plastic sheet over a mold. | General process of heating plastic sheets and shaping them with molds (includes vacuum forming). |
| Process Specificity | Subset of thermoforming focused on vacuum suction. | Umbrella term for several methods: vacuum forming, pressure forming, twin-sheet forming. |
| Detail Level | Moderate detail; good for simple or large parts. | Can achieve higher detail with pressure forming or twin-sheet methods. |
| Cost | Lower tooling cost, best for prototypes and short runs. | Cost varies—some methods more expensive, but more versatile. |
| Applications | Trays, enclosures, housings, packaging. | Packaging, medical trays, automotive panels, consumer products. |
