Today, we welcome the ninth of the twenty-four solar terms – Grain in Ear. Also known as "Busy Planting", Grain in Ear signifies the ripening of awned crops like wheat and the emergence of awns; and the urgent sowing of summer grains (rice, beans, millet) – a cycle of harvest and planting. For modern agriculture, missing the window of opportunity for harvesting and planting can impact the entire season's yield.
During this crucial harvest and planting season, the stability, durability, and precision of agricultural machinery are paramount. Failure or wear of any non-standard part can lead to downtime, delays in planting, and ultimately, reduced yields.
This is precisely the problem that Longway excels at solving. We specialize in providing custom-made parts for agricultural machinery through casting, forging, and machining processes. Whether it's harvester parts like blades and guards, or tractor parts like transmission components and gearbox housings, Longway provides stable, durable, and reliable support for your agricultural equipment.

The high-temperature steel billet slowly stretches on the ring rolling mill, and the tolerances are strictly controlled for each rolling pass from the billet to the finished ring forging. The rolling process straightens the metal flow lines and eliminates inherent defects such as loose porosity inside the billet.
As a controlled plastic deformation process, forging refines the internal microstructure through materials plastic deformation, improves material density and integrity, stabilizes mechanical properties, ensures consistent surface quality, and enhances raw material utilization efficiency. By optimizing grain flow and eliminating internal defects, the forged components exhibit superior strength, fatigue resistance, and reliability compared to counterparts produced by casting or machining.
Due to these advantages, forging has become the preferred manufacturing method for critical components in industries such as agricultural machinery, construction equipment, mining machinery, power transmission systems, fire protection piping, pumps and valves, and water treatment systems.

More than just selling pulleys, we're the one solving our clients' "transmission anxiety."
Those unfamiliar with industrial equipment often think of pulleys as just ordinary small parts. But anyone who's worked on a production site knows that pulley misalignment, wear out, or runout errors will directly affect production efficiency.
Recently, we received a request from a machinery manufacturer in Italy. They hope to switch supplier to get better quality pulleys, because their previous pulleys occured transmission instability issues in less than six months.
Given in above information, we provided our production solution based on their equipment's operating environment. We mainly focused on the key details: groove dimensional accuracy, concentricity control, and dynamic balancing inspection.
Actually, what clients care about most isn't price, but whether their equipment will running well with assembly of our components.
This is exactly what we do: providing one-stop customized parts manufacturing services for industries such as agricultural machinery, construction machinery, mining equipment, power transmission systems, fire-fighting pipe fittings, pumps and valves, and water treatment—covering investment casting, sand casting, forging, as well as CNC machining, surface treatment, heat treatment, and assembly.

Small components, Big Impacts: How Longway Uses Non-Standard Fasteners to Solve Industrial Connection Problems
In the industrial world, bolts and nuts are often the most inconspicuous items. But have you ever considered that—a hydroelectric generator might shut down simply because a single nut loosened due to vibration; the soaring maintenance costs of a cross-sea bridge might stem from hundreds of small parts being unable to withstand salt spray and temperature differences…
The more basic the component, the less it should be treated "good enough."
Baoding Longway Trading Co., Ltd. specializes in non-standard mechanical parts. We not only provide customized non-standard mechanical parts, but also leverage investment casting, sand casting, forging, cnc machining, and subsequent surface and heat treatment to create customized connection solutions for every demanding working condition. From agricultural machinery to construction machinery, from mining equipment to power transmission systems, from fire-fighting pipe fittings to pumps and valves, we use an "extraordinary" fastener to solve the problems of "not being able to tighten, not being able to lock, and not being able to find the right parts" for global OEMs.

How to Choose the Right Production Solution for Small Customized Components Projects?
For such projects, the primary concern for purchasing and engineers is not the mold design itself, but rather ensuring the dimensional accuracy, surface quality, and batch consistency of the components, while controlling subsequent processing costs.
Take a cantilever connector we produce for a client as an example. This part has a complex structure: a slender shank with a single hole at one end, a thick fl**ge with two holes at the other, and a reinforcing rib in the middle for transition. During production, key attention needs to be paid to hole position accuracy, the uniformity of pouring in the thickness transition area, and the stability of subsequent machining…
For your small project, we suggest you consider the following when selecting a supplier:
1. Whether they have the capability to coordinate multiple processes such as sand casting, precision casting, forging, and machining;
2. Whether they can guarantee the dimensional consistency and surface quality of castings under small-batch conditions;
3. Whether they can flexibly handle complex part structures and reduce the risk of defects;
4. Whether they provide full-process support from production to inspection to ensure that the final parts can be directly assembled and used.
Longway supports small-batch customized parts production, providing a one-stop service including sand casting, investment casting, forging, cnc machining and necessary post-processing steps. Our parts are widely used in agricultural machinery, construction machinery, mining equipment, power transmission systems, fire-fighting pipe fittings, pumps and valves, and water treatment industries. We are committed to helping our clients achieve stable delivery and cost-effective solutions in small-batch projects.

Water Glass vs. Silica sol – What’s the Real Difference in Investment Casting?
A long-term customer recently asked me:
“I’ve never fully understood – what’s the difference between water glass and silica sol?”
It’s a great question. And the answer is not just about chemistry – it’s about cast quality, cost, and capability.
Here’s a quick side-by-side, based on what we actually see on our shop floor at Longway.
🔹 Wax pattern
• Water glass: low-temp wax, softer, moderate dimensional stability
• Silica sol: medium-temp wax, higher hardness & surface finish
🔹 Shell building – the real dividing line
• Water glass: chemical hardening (ammonium chloride), 2–4 hrs per layer, lower strength
• Silica sol: physical hardening (air drying), 8–24 hrs per layer, high strength, zircon sand/mullite face coat
🔹 Dewaxing
• Water glass: hot water (90°C+), efficient but higher shell impact risk
• Silica sol: steam autoclave – clean wax removal, lower crack risk
🔹 Firing
• Water glass: 800–900°C – strength drops at high temp
• Silica sol: 1000–1100°C – excellent hot strength for high-temperature pouring
🔹 Pouring capability
• Water glass: mainly carbon steel & low alloy steel
• Colloidal silica: stainless steel, heat-resistant steel, high-temp alloys – ideal for thin-wall complex parts
🔹 Surface & finishing
• Water glass: Ra 6.3–12.5μm, more orange peel, more grinding
• Silica sol: Ra 3.2–6.3μm, near net shape, much less machining
At Longway, we have decades of expertise and practical experiences in both water glassand silica sol investment casting, which enable us to flexibly choose the appropriateprocess according to customer needs. Complied with different national material standardsof carbon steel, stainless steel, and alloy steel, we are pleased to see our products performing well in the global OEMs' machinery and equipment across various industrieslike agricultural machinery, construction machinery, mining equipment, power transmission systems, fire-fighting pipe fittings, pumps and valves, and water treatment industries.
