Thread pitch is the distance between adjacent threads on a fastener, measured either as threads per inch (TPI) for imperial fasteners or millimeters between threads for metric fasteners. In this article, we’ll explore what thread pitch means, how it’s measured, and why it matters for precision machinery. We’ll also provide… <a href="https://www.plastiform.info/en/blog/engineering/thread-pitch-definition-charts/" class="read-more">Read More</a>
Acme threads are very common in all sorts of everyday machinery. You’ll encounter them in many different types of machines.However, the specific reason why that distinctive 29° flank angle appears so consistently in engineering blueprints is not that easy to find.Short answer : This geometry is not a coincidental outcome. <a href="https://www.plastiform.info/en/blog/engineering/acme-threads-the-complete-guide/" class="read-more">Read More</a>
Ever wondered why the American Petroleum Institute, or API, specs even came to be?Well, picture this: You’ve got a massive steel pipe, diving down through the seabed, snaking several kilometers underground, and then, eventually, carrying highly pressurized oil and gas all the way back up to the surface. Along that… <a href="https://www.plastiform.info/en/blog/engineering/api-thread-standards-complete-overview/" class="read-more">Read More</a>

Shrinkage in Metal Casting is a constant companion in our world of mechanical engineering, specifically when we’re dealing with cast metals.It’s a sneaky phenomenon that can turn a perfectly designed component into something…Well, not quite right. That moment when you realize the final piece isn’t quite the dimensions you meticulously planned. <a href="https://www.plastiform.info/en/blog/engineering/shrinkage-in-metal-casting-and-how-to-prevent-it/" class="read-more">Read More</a>
Plastiform products are frequently used by OCTG* (Oil Country Tubular Goods) manufacturers to carry out the control and inspection of API threads, tubings and casings.* OCTG is a specific family of steel pipe designed for oil drilling, extraction and transportation of oil and natural gas.IntroductionFunction of threadsThreads on oil well… <a href="https://www.plastiform.info/en/blog/metrology/api-thread-inspection-using-impression-material/" class="read-more">Read More</a>
Plastiform P80 Ra, as its name suggests, is a product capable of copying the Ra roughness of a surface and reproducing it identically. This ability allows it to be used in cases where the surface to be measured is not accessible to the measuring instrument.Roughness with PlastiformDefinitionRoughness corresponds to… <a href="https://www.plastiform.info/en/blog/quality-assurance/plastiform-roughness-control-procedure-with-contact/" class="read-more">Read More</a>
Rolls of masking tape Masking aims to protect areas of a part against surface treatment. Generally, masking is a long and tedious operation that requires handling and lots of adhesive.Adhesive tape is the most commonly used masking tool in industry, yet it’s far from being the most… <a href="https://www.plastiform.info/en/blog/engineering/how-to-substitute-masking-scotch/" class="read-more">Read More</a>
Quality control is a procedure implemented by companies to ensure product conformity.It is carried out by a quality controller with (or without) the assistance of other production stakeholders.Conformity is established based on criteria developed by the company or through mutual agreement between a supplier and a customer.

Traceability is a concept that dates back over 3,800 years to ancient times.In those distant times, people used seals or hot irons to authenticate their exchanges.Today, traceability is ubiquitous in industry, where it provides all necessary information about a product.This information is tracked at each stage of the production chain,… <a href="https://www.plastiform.info/en/blog/quality-assurance/traceability-in-the-industry-what-is-it/" class="read-more">Read More</a>
During machining, no matter how precise the machine used is, surfaces will always have irregularities. These irregularities are micro-geometric roughness caused by the imperfection of cutting tools (yes, perfection doesn’t exist!).Measuring these imperfections is crucial. For over 80 years, surface finish measurement has been used to improve… <a href="https://www.plastiform.info/en/blog/metrology/the-roughometer-measuring-surface-condition/" class="read-more">Read More</a>
Threads are helical grooves commonly known as screw threads. When a thread is inside a cylinder (female thread), it’s called a tapped hole. Conversely, threading refers to an external thread (male thread).Thread, bore, and tap inspection is a common requirement in industry, as numerous parts feature this type of geometry. <a href="https://www.plastiform.info/en/blog/quality-assurance/how-to-inspect-threadings-without-destroying-them/" class="read-more">Read More</a>
Non-Destructive Testing (NDT) is a discipline grouping together processes and techniques to identify characteristic differences, welding defects, and discontinuities, all while avoiding any harm to the original part.The use of non-destructive testing measurement techniques is essential for the industry. Indeed, NDT techniques are very important for a company because they… <a href="https://www.plastiform.info/en/blog/quality-assurance/non-destructive-testing-or-ndt/" class="read-more">Read More</a>
