Introduction: Why choose thermoforming technology?

Do you need to customize large plastic parts, such as equipment housings, car body kits, special vehicle interiors, display cabinets, or industrial protective covers? In the face of these needs, thermoforming technology (especially vacuum forming and pressure forming) may be your best choice. Hengtuopu, as an industry with 20+ years of experience in thermoforming manufacturing, will analyze the advantages, material selection and practical application scenarios of thermoforming technology in detail to help you easily find a suitable customized solution.

Thermoforming is a technology that heats and softens plastic sheets and then forms them through molds. It is widely used in the manufacture of large and complex plastic parts. Whether it is a sturdy and durable industrial housing or a light and beautiful display part, thermoforming can provide an efficient and economical solution. So, how to choose the thermoforming method that suits you? This article will take you step by step in a “problem-solving” way, combined with cases.

What is thermoforming? Understand the difference between vacuum forming and pressure forming

What are the types of thermoforming technology?

Thermoforming is mainly divided into vacuum forming and pressure forming. What is the difference between the two processes? In short:

Vacuum forming: The heated plastic sheet is adsorbed to the mold through vacuum negative pressure, which is suitable for manufacturing large, simple structure parts, such as truck linings or large plastic shells.

Pressure forming: Using a combination of positive and negative pressure, the forming accuracy is higher, which is suitable for parts that require complex details, such as medical equipment panels.

Case: Imagine you need to customize a large plastic display cabinet for a coffee shop. Vacuum forming can quickly produce the basic shape of the cabinet, while pressure forming can further carve out exquisite surface textures, making the display cabinet look more high-end.

Expert Tip: According to research by Productive Plastics, vacuum forming costs are usually 20%-30% lower than pressure forming, but pressure forming is better in detail performance. Which method to choose depends on your budget and product complexity.

Choose the right material: Make your plastic parts more durable

How to choose the right material for large plastic parts?

In thermoforming, the choice of materials directly affects the performance, cost and service life of the parts. The following are several common thermoforming plastic materials and their detailed application scenarios:

ABS (Acrylonitrile-Butadiene-Styrene):

Features: high strength, impact resistance, easy processing, and the surface can be painted or screen-printed.

Applications: large equipment housings, automotive interiors, industrial pallets.

Case: A logistics company needs to customize a sturdy truck lining, and ABS is the first choice due to its impact resistance and cost-effectiveness.

Advantages: Suitable for scenarios requiring high strength and medium cost, with a smooth surface after processing, suitable for brand logo printing.

HIPS (High Impact Polystyrene):

Features: low cost, good formability, light weight, but slightly lower strength than ABS.

Applications: retail display racks, billboards, disposable packaging.

Case: A supermarket chain needs a lightweight promotional display rack, and HIPS can be quickly formed and is affordable.

Advantages: Suitable for projects with limited budgets and low strength requirements.

PC (polycarbonate):

Features: transparent, high temperature resistant, ultra-high strength, excellent UV resistance.

Applications: medical equipment housings, outdoor protective covers, aviation parts.

Case: A hospital needs to customize a transparent equipment housing, and PC materials can ensure clarity and long-term durability.

Advantages: Suitable for scenes requiring high transparency or outdoor weather resistance.

PVC (polyvinyl chloride):

Features: chemical corrosion resistance, good flame retardancy, and moderate cost.

Applications: chemical laboratory equipment covers, pipe housings.

Case: A chemical plant needs a corrosion-resistant equipment protective cover, and PVC is an ideal choice.

Advantages: Suitable for chemical environments or scenes requiring fire resistance.

PETG (Polyethylene terephthalate):

Features: High transparency, good toughness, easy secondary processing.

Applications: Medical packaging, retail display covers.

Case: A pharmacy needs a transparent protective cover, and PETG combines beauty and durability.

Advantages: Suitable for parts that require high transparency and complex post-processing.

Does your project need to be lightweight or high strength? Is it for indoor use or does it need UV resistance and chemical corrosion resistance? Tell me your needs and I can help you recommend a more suitable material!

Authoritative citation: According to Plastic Ingenuity’s material guide, ABS, PC and PVC are the most widely used in heavy gauge thermoforming, accounting for more than 70% of the market share. When choosing materials, you need to consider the use environment, budget and processing requirements.
