Tinplate Necking Cans – Eliminate Neck Cracks: Elongation & Multi-stage Necking
Introduction In the mass production and processing of tinplate necked cans, the necking process is a core link that determines the forming qualification rate and sealing performance of can bodies. Many cans gradually show problems such as unstable wall thickness, tiny wrinkles and hidden cracks at the neck position after necking forming, filling and sealing. These defects rarely appear defective when products are off the production line, but most of them occur during warehousing, transportation and end use, easily leading to batch scrapping, order delays and damaged quality reputation. Especially with the rising demand for lightweight and customized special-shaped cans in recent years, the combination of ultra-thin materials and complex necking shapes has plunged many manufactur...Learn more -
Final Solution to Valve Blockage of Tire Repair Cans: Large Flow Channel Valve & Internal Can Cleanliness Control
I. Four Core Causes of Valve Blockage for Tinplate Tire Repair Aerosol Cans 1.1 Mismatch Between Particle Size and Standard Valve Flow Channel Specifications The minimum flow aperture of mainstream universal aerosol valves is fixed at 0.3mm, while the filler fibers in conventional tire repair fluid have a particle size range of 0.15mm to 1.3mm. Coarse fibers exceeding the aperture size are easily stuck at the valve inlet. In fact, most formula developers only focus on the sealing effect of tire repair, ignoring the matching test of powder particle size and valve specifications. Isn’t this the core reason for frequent blockage of high-fiber formula tinplate tire repair aerosol can? 1.2 Material Sedimentation and Agglomeration Caused by Long-term Warehouse Storage Fluctua...Learn more -
Golden Aerosol Cans Turn Hazy and Whitened After Arrival? Don’t Check the Ink — The Root Cause Is the White Primer Blanking Process
Many procurement and quality control personnel often encounter a tricky inspection problem: customized golden tinplate aerosol cans and silver high-gloss cans feature perfect luster and flawless appearance when leaving the factory. However, after long-distance transportation, the can surface turns whitened and hazy with foggy white spots, looking like aged old products. This issue usually leads to severe consequences including full-container rejection, rework compensation and even supplier elimination from the brand’s supply chain. Most partners will first suspect ink quality defects upon receiving goods. Yet professional on-site tests always confirm that the ink layer maintains perfect adhesion, abrasion resistance and color fastness. Whitening and hazing on the exterior of printe...Learn more -
Necked-in vs Straight-Wall Tinplate Aerosol Cans: Why Strength Differs by 30% Under the Same Design
Batch structural damage often occurs to tinplate aerosol can after long-distance container transportation. A recent deodorant can shipment suffered severe bottom bulging and body denting on straight-wall cans, resulting in full-batch rejection. The aerosol industry universally pursues lightweight production and tinplate material savings. However, simple wall thinning always compromises transportation pressure resistance. This creates a common dilemma for aerosol designers and manufacturers: balancing lightweight cost control and structural reliability. Real transportation conditions are far harsher than laboratory static tests. Superimposed stacking pressure and high-temperature internal pressurization easily trigger lightweight tinplate can dome reversal. Most teams st...Learn more -
Leather Care Aerosol Cans: Silicone Oil Causes Pressure Decay and Half-Can Spraying Failure
Many leather care practitioners encounter a common and troublesome problem: after leather care aerosol cans are launched on the market, frequent end-user complaints arise. The spray fails to produce a uniform mist and only releases thin streams when half or one-third of the product remains, completely losing its practical effect. This is a prevalent after-sales pain point in the leather care industry. Many people attribute the issue to insufficient propellant filling, but in fact, most cases of half-can failure and internal pressure loss stem from organic silicone oil, an essential ingredient in care formulas. With years of experience in custom silicone-resistant leather care aerosol cans, SAILON analyzes the root causes and fundamental solutions to this common industry problem bas...Learn more -
Industrial Release Agent Aerosol Cans: Residues Causing Mold Contamination and Skyrocketing Cleaning Costs
Most injection molding and die-casting enterprises face a hidden universal pain point. The common use of industrial release agent aerosol cans quietly increases production losses and reduces overall capacity. After investigating many small and medium-sized processing factories, we found that most workshops have to stop production to clean molds twice per shift, with each cleaning lasting 45 minutes, resulting in a cumulative production time loss of over 200 hours every year. Who would have thought that release agents, originally designed to assist demolding and improve product quality, have become the core cause of mold contamination, frequent cleaning and reduced production capacity due to residual scale? 1. Release Agent Residual Scale: The Hidden Production Loss Black Hole in...Learn more -

Hairspray Aerosol Can Discoloration Root Cause: Accelerated Test Method and Qualification Criteria for Inner Coating Swelling in High-Alcohol Formulations
Discoloration and off-flavor of hairspray and shaving foam aerosols during shelf life are mainly caused by ethanol-induced inner coating swelling failure of tinplate aerosol cans. When the ethanol content of the formula reaches 70%-95%, the inner wall coating of ordinary aerosol cans will swell due to solvent penetration, leading to reduced adhesion and iron ion migration that contaminates contents. The alcohol resistance of hairspray & shaving foam aerosol cans directly determines the long-term storage quality of cosmetic aerosol products. Based on Fick’s diffusion law, SAILON has established a 55°C/7-day ethanol accelerated swelling test system with four quantitative evaluation criteria, which can quickly predict the alcohol resistance of inner coatings and accurately evaluat...Learn more -
Aerosol Tin Can Neck Ovality Causing Slow Leakage? Infrared Laser Online Inspection and Production Line Rejection Solution
Excessive aerosol can neck ovality is a core hidden cause of shelf-life leakage and soaring seam leakage rate, as well as a frequent pain point in quality control for high-speed can production lines. With years of experience in custom tinplate aerosol can production and quality management, SAILON has found that most gasket sealing failure issues of aerosol cans stem from can mouth out-of-roundness and radial dimension deviation caused by necking deformation, rather than seaming equipment or sealing accessories. Many manufacturers invest heavily in optimizing back-end filling and sealing processes, yet ignore the source control of front-end necking deformation, ultimately leading to mass defective products and frequent after-sales complaints. 1. Core Definition: What is Can Neck ...Learn more -
Tinplate Can Propellant Selection: Influence of LPG, DME and Compressed Air on Can Wall Thickness and Valve Accessories
In the field of aerosol packaging manufacturing, the structural design of tinplate cans is inseparable from the adaptation of propellants. Different gas media not only change the atomization effect of spray, but also directly determine the wall thickness standard, internal coating formula and valve sealing component selection for custom aerosol tinplate cans. With years of deep engagement in aerosol can R&D and production, SAILON has dealt with a large number of actual working condition cases. Many manufacturers only focus on appearance and capacity, ignoring hidden production troubles such as tank deformation, interface leakage and shortened shelf life caused by physical properties of propellants. Gas propellants are mainly divided into liquefied and compressed categories. ...Learn more
