PETG/PET Injection Molding

SeaskyMedical offers the absolute Polyterephthalate alcohol ester (PETG) injection molding services for medical equipment parts and medical disposables manufacturing. 

PETG/PET Injection Molding in Seaskymedical

The chemical name of PET is Polyterephthalate alcohol ester and is also called polyester. As of now, the highly utilized by consumers is the GF-PET, primarily for the bottle preform. It retains a powerful hygroscopicity at elevated temperatures. The PETG injection molding procedure is one of the best and most crucial technologies for refining plastic, PET plastic parts, etc. 


SeaskyMedical primarily concentrates on the improvement and creation of medical injection molded products. We offer the best quality PET  injection molding services at an affordable price. 

We can help with product design and expansion, mold planning and building, material selection, and injection molding, among other things. You can get in touch with the experts at SeaskyMedical for any queries related to PET molding services. 

Custom Various PETG/PET molding services

In our day-to-day life, medical plastic injection has a critical role, which is why healthcare establishments have to make sure to use only the best quality products in order to ensure positive results. SeaskyMedical provides the following PETG molding services, including custom options.

Medical TPU Injection Molding

Injection molding is one of the best affordable way to manufacture medical parts. Medical equipment packaging, medical devices, and surgical disposable product are some of the typical products made from medical injection moulding by plastic medical device manufacturers.

Medical Overmolding

In medical overmolding procedure, more than two molded parts are chipped together. The PET plastic material utilized can be the same or different, but the combinations of plastics are nearly infinite. We perform this two-stage process with maximum precision.

Medical Insert Molding

Insert injection molding is performed near different plastic inserts or pieces. In general, most of the time ordinary parts are injected. But, depending on the client’s necessities, complicated PETG components insertion also happens. 

Medical Micro Molding

Micro injection molding procedure develops plastic parts for weights from 1 to 0.1 grams with a wide tolerance range of 10 to 100 microns. This process allows the generation of particular micro-featured components.

Compression molding

Compression molding is a technique where the molding substance is heated and is fixed in an open and heated mold nook. This process makes it possible to produce different PET molded parts in various sizes, lengths, thicknesses, and complexities.

Ultrasonic Bonding

Ultrasonic molding procedure employs high-power ultrasound in order to wilt and mold thermoplastic polymers. The ultrasonic vibrations are utilized to incorporate metals, plastics, and even distinct metals to assure quality.

What is PETG/PET plastic material?

Polyester, Polyterephthalate alcohol ester, or PET is a primarily used material in injection molding. The glycol-modified PETs are known as PETGs or copolyesters, and this transformation is accomplished by putting another glycol during polymerization. In general, this material has several properties like precision, toughness, stiffness, and clarity.

What are the PETG/PET material properties?

PETG PET material

The PETG or PET-G are called Polyethylene terephthalate glycol. It is a thermoplastic polyester that provides substantial durability, chemical resistance, and formability for medical component molding. Below, we have some of the essential properties of PETG:

Extrusion Temperature

It comes with an extrusion temperature ranging between 220 degrees Celsius and 260 degrees Celsius.

Print Speed

PETG is very suitable for 3D printing and retains a print speed of 40 to 60 mm/s.

Impact Resistance

PETG is comparatively less fragile than other materials and shows great resistance to impact.

Tensile Strength

PETG comes with a tensile strength of 7,000 psi.

Water Absorption

The water absorption rate of PETG for 24 hours is 0.20%.

Difference between PETG and ABS: PETG Vs. ABS

When it comes to durability and strength, PETG and ABS stand at the top list. However, there are some key differences that make each of them best in specific aspects: They are as follows:


From a health standpoint, PETG molding is relatively pleasant with little to no minimal odor. However, ABS can have mild to strong printing odors.

Hygroscopicity And Storage

It is relatively easy to store ABS. PETG is slightly more hygroscopic and easily consumes moisture from the air.

Temperature Requirements

In comparison to PETG, the temperature requirements of ABS are much more high. ABS demands high-level temperatures which sometimes cross 100 degrees Celsius.

Ultimate Tensile Strength

When it comes to maximum tensile strength in XZ orientation, ABS has 32 MPa. Meanwhile, PETG material features a tensile strength of 50 MPa.

Why We Use PETG/PET material for
Injection Molding

PETG eliminates the hazing that can affect PET and lessens the crystalline impact that can result in PET becoming brittle. The plastic injection molding machines utilize PETG to generate more flexible and softer medical disposables that feature a comfortable grip.

PETG is used in injection molding because of its considerable reliability and chemical resistance

PET injection molding also has incredible formability that eases the manufacturing process.

Because of PET injection molding’s low forming temperatures, this material may be brushed and pressure-formed speedily, as well as heat-bent.
