We turn and mill PBI, including Celazole, and PBT to technical drawings. We select the grade for the component’s operating temperature, loads and electrical requirements.
We specialise in PBI CNC machining and PBT machining. We machine these plastics where maximum stability and resistance are required, in aerospace, electronics and high-temperature applications.
We work with PBI and PBT grades selected to meet the project requirements.
PBI and PBT are available as rods, plates and machined blocks.
Available forms of both materials:
PBI – key properties:
PBT – key properties:
Aerospace insulation and specialist spacers for the space industry are applications for both materials. PBI is used where dimensional stability and radiation resistance are required.
Electronic housings, including fuse housings. With its very good electrical-insulation properties, PBT is a standard choice for electronic components. PBI is used for high-temperature applications. PBI and PBT are used for CNC-turned insulators.
We machine thermal insulators and high-temperature guides from PBI. PBI’s exceptional heat resistance and dimensional stability make it the material of choice where other plastics lose stability.
PBT is widely used in automotive applications because of its strength, rigidity and stable electrical properties. We make housings with increased fire resistance from PBI or, for PBT, from PBT FR grades available only where the project requires them. Standard PBT is not fire-resistant.
PBI and PBT applications by industry:
Typical CNC-machined components:
We offer:
We machine PBI and PBT where maximum stability and resistance are required. Standard PBT is not fire-resistant. ANBI-TECH holds ISO 9001:2015, ISO 14001:2015 and PN-EN ISO 45001:2024.
Choose ANBI-TECH as your partner for machining PBI or PBT and work with a company focused on your success. We provide high quality, competitive prices and reliable service. Our experienced team works closely with customers to understand specific requirements and propose optimal solutions.
We build long-term relationships based on trust, reliability and repeatable results. Our flexible approach accommodates changing requirements while maintaining quality standards and delivery timeliness.
Technical consultations help optimise designs for PBI and PBT machinability, potentially reducing costs while improving functionality. Our team provides reliable assessments and recommendations based on many years of manufacturing experience.
We coordinate the complete part-delivery process to supply a finished component that meets the specification.
Our aim is to provide products and services of the highest standard, making us a preferred partner for current and future PBI and PBT machining orders. Contact us to discuss your project requirements.

Yes. We machine PBI and PBT where maximum stability and resistance are required. We turn and mill both materials as rods, plates and machined blocks.
PBI, or polybenzimidazole, is a high-performance plastic with unrivalled thermal and dimensional stability. It operates continuously up to +310°C and briefly up to +400°C. It is resistant to radiation and wear.
PBT, or polybutylene terephthalate, is a versatile, rigid and strong thermoplastic. It has very good electrical-insulation properties and is resistant to radiation and wear. It is widely used in electronics and automotive applications.
PBI and PBT are two different plastics with distinct application profiles. PBI stands out for very high heat resistance and dimensional stability, so it is selected for aerospace applications and high-temperature insulation. PBT is a rigid, strong thermoplastic with very good dielectric properties, used in electronics and automotive applications.
The best-known PBI trade name is Celazole®. The best-known PBT trade name is Crastin®. We work with both materials under these brands.
PBI is used mainly in aerospace, thermal insulators, high-temperature guides and specialist spacers for the space industry. PBT is used in electronic housings, fuse housings and automotive components. Housings with increased fire resistance are made from PBI or, for PBT, from flame-retardant PBT FR grades available only where the project requires them. Standard PBT is not fire-resistant. We also machine both materials as CNC-turned insulators.

I can wholeheartedly recommend Anbi-Tech as a reliable and professional partner in machining and in manufacturing parts for the pharmaceutical industry. This is the third company where I have had the pleasure of working with Anbi-Tech, and the cooperation has been of the highest standard every time.
The pharmaceutical industry is exceptionally demanding: precision, on-time delivery, material quality and a full understanding of the customer’s needs all matter. Anbi-Tech has repeatedly proved that it is very well suited to this environment. The company has manufactured change parts, spare parts, filling needles, conveyor screws, components for dispensing powders and liquids, and many other production components for us.
The quality of the parts deserves particular recognition, whether they are made from 316L and 304 stainless steel or plastics such as POM, polyurethane and polycarbonate. The components are manufactured to a very high standard, with close attention to accuracy and detail, which is crucial in our industry.
Anbi-Tech has literally ‘saved our skin’ on many occasions in emergencies where time, a rapid response and a flexible approach to the customer mattered. A major strength of the company is its modern machinery, which enables it to complete even highly demanding projects while maintaining the highest standard of workmanship.
The people are equally important: the company’s staff always show complete commitment and a willingness to cooperate and provide technical support. Their extensive experience, professionalism and collaborative approach to customers are clear to see.
In pharmaceuticals, the ‘paperwork’, meaning certificates, is also important. The certificates have never been questioned during customer or regulatory audits, for example by GIF.
I strongly recommend working with Anbi-Tech to any company looking for a proven, reliable and quality-focused technical partner.
Dariusz Stachowicz, Senior Maintenance Manager, Polfa Warszawa S.A.
We had a very good experience working with Anbi-Tech on a new production line project for a bottling plant. Using a bottle sample and components from the old line, its engineer prepared the design and documentation for new change parts in SolidWorks. Anbi-Tech then manufactured timing screws, star wheels, drive components, bottle orienters, bottle turners and feeding components, among other items.
A major advantage is the end-to-end approach, from analysis and design through to the manufacture of finished components. Their considerable technical experience, precision and ability to solve unusual problems are clear. I recommend them.
Bartłomiej Ć, Specialist, ORLEN
We work with Anbi-Tech to manufacture parts and technical components for our projects. We value them above all for their workmanship, on-time delivery and excellent communication. When requirements are unusual, they can advise us and find a solution instead of simply manufacturing a part from a drawing. A reliable partner that I am happy to recommend.
Marek P., Production Manager, Triccor
A reliable company with extensive experience! They manufacture parts from steel, aluminium and specialist plastics such as POM and PTFE. Every service, whether turning, milling or CNC cutting, is carried out perfectly and with attention to the smallest detail. Excellent communication, professional advice and consistently on-time delivery. I wholeheartedly recommend them to anyone who needs reliable components.

For a quotation, send a PDF or DXF drawing or a STEP model with dimensions. State the material, the number of pieces and the quality requirements. A photograph of the part alone, without dimensions, does not allow a reliable quotation to be prepared.
If the project combines several operations, we will agree the scope of machining, inspection, assembly and processes carried out by partners.
