Frequently Asked Questions (FAQ) – Blow Molding Products

Welcome to HDC’s FAQ section on Blow Molding Products, your resource for understanding the intricacies of this versatile manufacturing process. At HDC, we specialize in providing custom blow molding products and solutions tailored to your unique requirements. Whether you’re exploring the world of blow molding for the first time or seeking to enhance your existing knowledge, our FAQ is here to offer insights and answers.

What Is the Blow Molding Process?

Hollow blow molding, commonly referred to as blow molding, is a molding method for producing hollow plastic components. In this process, plastic material in a highly elastic (near-viscous) state is placed within a mold cavity. By utilizing compressed air, the material is inflated, causing it to conform closely to the mold cavity walls (concave mold). After cooling and solidification, hollow plastic components are formed. There are various methods for hollow blow molding, including extrusion blow molding, injection blow molding, multi-layer blow molding, and sheet blow molding. This process is primarily used for manufacturing hollow plastic containers with smaller neck diameters and larger body diameters, such as bottles and cans.

Which Type of Blow Molding Is the Most Commonly Used?

Extrusion blow molding is the most widely used method for manufacturing hollow thermoplastic components. Extrusion blow molding involves taking molten thermoplastic material extruded from an extruder, introducing it into a mold, and then injecting air into the material. The molten material expands under the influence of air pressure, conforming to the mold cavity walls, and finally cools and solidifies into the desired product shape. It is closely tied to our daily lives, as most of the plastic bottles we come into contact with on a daily basis are essentially produced through extrusion blow molding.

What Is the Best Material for Blow Mold?

High-density polyethylene (HDPE) is often considered the best material for blow molding due to its excellent properties. It’s a strong, durable material that’s FDA-approved and considered the safest type of plastic. HDPE is translucent and can be colored easily. It’s used in many products, including Bottles for consumer liquids, Coolers, Carrying cases, Fuel tanks, and Industrial drums.

Can PVC be Used for Blow Molding?

Yes, Polyvinyl Chloride (PVC) is a translucent thermoplastic that can be used in blow molding. PVC is known for its durability, dimensional stability, and resistance to flame, chemicals, and abrasion. It comes in rigid and soft resin forms, and the soft resin is typically used in blow molding.

What Temperature Is Blow Molding Done?

The temperature for blow molding typically ranges from 180°C to 230°C (356°F to 446°F), depending on the type of plastic material used.

What Is The Typical Gas Pressure for Blow Molding?

The air pressure in blow molding is typically in the range of 0.2-1.0 MPa, primarily determined by the viscosity of the melted plastic. For plastics with low viscosity, such as nylon and polyethylene, which are easy to flow and expand, the molding air pressure can be lower. In contrast, plastics with high viscosity, like polycarbonate and polyoxymethylene, have poorer flow and expansion properties, requiring higher pressure.

What Are The Pros And Cons of Blow Molding?


  • Low production costs: Lower production costs make it suitable for high-volume manufacturing.
  • Low residual material stress: Exhibits high performance in tensile strength, impact resistance, bending, and resistance to various strains and environmental factors.
  • Seamless products: Minimal waste and no visible seams or joints.


  • High mold costs: The design and manufacturing requirements for molds are quite demanding. and it may not be economical for small production runs.
  • Difficult temperature control: It is challenging to control the temperatures of both the parison and the blow molding process. When the temperature is too high, the melted material has low viscosity, making it prone to deformation, resulting in uneven thickness during parison transfer. When the temperature is too low, the product often contains more internal stress, which can lead to deformation and stress fractures during use.

Which One Is Cheaper, Blow Molding or Injection Molding?

Blow molding is suitable for producing hollow products with uniform wall thickness, and it offers better efficiency and cost-effectiveness in large-scale production compared to injection molding. However, the cost comparison depends on factors like material, part design, and production volume.

What Is the Difference Between Blow Molding And Roto Molding?

Blow molding forms hollow parts by inflating a heated plastic material inside a mold, while roto molding (rotational molding) rotates a mold with powdered plastic inside to create a hollow part. Blow molding is typically more precise and suited for high-volume production.

Is Blow Molding Environmentally Friendly?

Blow molding can be environmentally friendly when using recyclable plastics and optimizing production processes. Recycling and reusing materials are common practices in the blow molding industry, contributing to sustainability efforts. However, like all manufacturing processes, it has environmental considerations that must be managed responsibly.
