Pipe manufacturing using CFRTP (Carbon Fiber Reinforced Thermoplastics) is gaining attention as a method that combines lightweight properties, high strength, and excellent mass productivity. The method introduced here utilizes a braided CFRTP preform, combining press molding and air injection to efficiently form pipe shapes. Compared with conventional CFRP pipe manufacturing, this process significantly reduces production time and offers cost advantages. 【Overview of CFRTP Pipe Molding】 Because CFRTP uses a thermoplastic resin matrix, it can be repeatedly softened by heating and hardened by cooling. This characteristic enables fast processing with a press machine. In this method, a braided CFRTP preform is used. The process begins by wrapping the braided preform around a tube-shaped base material. Thanks to the flexibility and fiber orientation freedom unique to braided structures: Strength can be adjusted by controlling winding angles Uniform pipe structures can be formed Required rigidity can be secured efficiently 【Molding Process Flow】 The process consists of four main steps: 1. Wrapping the Braided CFRTP Preform The flexible braided preform is carefully wrapped around a base tube. By adjusting the fiber orientation during wrapping, the rigidity and strength direction of the pipe can be optimized. 2. Press Molding in a Heated Die The wrapped assembly is placed in a mold shaped to the desired pipe geometry and hot-pressed. As the thermoplastic resin softens: Fibers conform tightly to the mold surface The outer shape is precisely defined 3. Air Injection After press forming, air is injected into the interior of the pipe. This internal pressure: Stabilizes the inner diameter Ensures uniform wall thickness Improves overall rigidity and dimensional accuracy 4. Cooling and Solidification While still set in the mold, the component is cooled. As the thermoplastic resin solidifies: Final strength is established Shape accuracy is fixed A lightweight, high-rigidity CFRTP pipe is completed 【Comparison with Conventional Methods】 Carbon fiber pipes are commonly produced using CFRP (Carbon Fiber Reinforced Thermosetting Plastics). In conventional manufacturing: Prepreg is wrapped around a mandrel The assembly is cured in an autoclave While this method produces high-quality pipes, it requires long heating and curing times, limiting productivity. In contrast, CFRTP pipe molding: Utilizes thermoplastic resin properties Enables short cycle times Allows rapid press-based processing Supports continuous production for standardized sizes Higher productivity directly contributes to cost reduction. 【Application Potential of CFRTP Pipes】 CFRTP pipes offer: Lightweight construction High impact resistance Fast manufacturing speed Potential applications include: Mechanical components Sporting goods Transportation equipment requiring weight reduction The braided preform structure allows more flexible fiber orientation design than traditional CFRP pipes, enabling performance customization according to specific application needs. 【Summary】 By combining braided CFRTP preforms, press molding, and air injection, this manufacturing method enables the production of lightweight and high-strength pipes in a short time. Compared with conventional autoclave molding: Production efficiency is significantly improved Manufacturing costs can be reduced Rapid prototyping and small-lot production are feasible Although size limitations exist, this process is highly effective for components within a practical dimensional range. If you are exploring lightweight, high-strength, and cost-efficient pipe solutions, CFRTP pipe molding presents a strong alternative worth considering. 【Contact Information】 Kawamura Kikai Co., Ltd.

Our company also performs injection molding using bio-plastics. In particular, we focus on developing and producing products using biodegradable resin “PLA (Polylactic Acid)” made from plant starch and sugars. This is a new molding solution that achieves a balance of functionality, design, and sustainability. ▪ Features and Technical Examples - Achieved thin-wall molding with 100% PLA (without blending petroleum-based resins), which was previously considered difficult. - World-first molding: wall thickness 0.65mm, flow length 135mm. - Applied long-accumulated know-how from reflector molding, etc. - Reduced resin usage through thin-wall design. - Weight reduction using MuCell® (microcellular foaming system). - Zero scrap with hot runner system. - CO₂ emission reduction by replacing petroleum-based resins. ▪ Applications and Deployment - Replacement of petroleum-based products with plant-derived materials. - SDGs-conscious novelty products to enhance corporate appeal. ◎ Consultation We handle everything from product planning, collaboration, mold manufacturing to mass production. Please feel free to contact us for injection molding with resins other than PLA. We also welcome inquiries for quotations and samples of our original products “Bio7”, “4Tiers”, and “N1”! ◎ Related Articles PLA Glass “Bio7”: https://ja.nc-net.or.jp/company/1285/product/detail/265575/ PLA Glass “4Tiers”: https://ja.nc-net.or.jp/company/1285/product/detail/265576/ PLA Glass “Foam”: https://ja.nc-net.or.jp/company/1285/product/detail/265581/ Heat-Resistant PLA Mug “N1”: https://ja.nc-net.or.jp/company/1285/product/detail/265578/ ◎ Contact Nissin Precision Machines Co., Ltd. – Head Office 〒146-0095 2-29-21 Tamagawa, Ota-ku, Tokyo, Japan TEL: 03-3758-1901 E-mail: gn_info@nissin-precision.com

[Machined SUS316L 3D shape, surface roughness, chemical/medical business] 【Material】 SUS316L 【Dimension】 Outer diameter φ95 【Lot】 1 to 100 pieces 【Precision】 ±0.05㎜ 【Processing method】 Machining, wire cut 【Industry/Application】 Chemical, semiconductor, medical business related 【Features】 This is a stainless steel precision item made of SUS316L that is used in the chemical and pharmaceutical industries. SUS316L clearly has inferior machinability when compared to SUS304. We chose and prepared a knife suited for SUS316L processing. As shown in the photo, the product has a round form, but through trial and error in setup and construction methods, we were able to finish it virtually entirely by machining. The slope at the top of the photo is where the liquid flows, so a severe surface roughness is required. Using optimal cutting tools and processing conditions, we are able to create a high surface roughness even when liquids flow through it. We carefully examine the blades and processing conditions used depending on the material and processing content, and strive to provide our customers with high-quality products in short delivery times. ☆Shimizu Trym Precision Inc., a manufacturer of precision parts and precision molds☆ 421-1 Shinden Nagasaki, Shimizu-ku, Shizuoka-shi, Shizuoka TEL：+8154-340-6631 FAX：+8154-340-5571 mail：eigyo@shimizutrym-pc.co.jp http://www.shimizutrym.co.jp/ We process anything from mold parts to industrial parts, precision parts, and ultra-precision parts regardless of material! by Nobita
