an oil-type mold temperature controller circulates heat-transfer oil to hold mold temperatures that water-based units cannot reach — typically up to 200°C on standard models and 300°C (occasionally 350°C) on high-temperature machines. It is the standard choice for high-temperature engineering plastics such as PEEK, PPS and LCP, for die-casting dies, and for any process needing stable high temperature at low operating pressure. This guide covers how they work, when to specify one, oil selection, maintenance and safety.

choose a water-type mold temperature controller when your mold runs at about 120°C or below (up to 160–180°C with pressurized high-temperature water) — water heats and cools faster, is cheap and clean, and suits most general injection molding. Choose an oil-type unit when the process needs sustained temperatures above roughly 120–150°C, commonly up to 200°C and as high as 300°C, because thermal oil delivers high temperature at low pressure without scale or corrosion. This guide compares the two on the factors that actually drive the decision.

Recycle injection-molding runners with beside-the-press granulators: setup, safe 10–30% regrind ratios, machine sizing by press tonnage and blade choice.

Four types of plastic granulators explained: powerful, low-speed beside-the-press, medium-low-speed and heavy-duty, with speed, noise, fines and use cases compared.

How to choose a plastic granulator in 2026: match material, size kg/h throughput, rotor, screen & SKD/9CrSi blades, and compare beside-press vs central systems.

Crushers, chillers, dryers, loaders, mixers, mold temperature controllers, cooling towers — can one Chinese factory really supply all of them and stay accountable? A 20-year manufacturer explains.

Standard beside-the-press granulators cannot swallow large blow-molded parts, bins, drums, pallets and thick purges. That is exactly the job of a heavy-duty plastic crusher with an oversized feeding mouth, a reinforced rotor and high cutting torque. This buyer-focused guide explains what actually distinguishes a capable large-hollow-part crusher from an undersized “heavy-duty” label: feed opening and chamber design, rotor and knife configuration, customizable knife steel (SKD-11 / 9CrSi), motor sizing, safety and maintenance access, and the total cost of ownership. It is written for injection molding plants, blow molding factories, packaging producers and plastic recyclers evaluating a bulky-waste granulator from a Chinese factory-direct supplier.

Sizing an industrial chiller is not about matching the chiller brand to your injection machine or simply picking the biggest unit you can afford. The correct chiller size is driven by the heat you need to remove per hour, then cross-checked against your machine clamp tonnage, material, cycle time, ambient temperature, and the water flow rate your mold requires. As a quick reference, 1 HP of chiller capacity is roughly 3,000 kcal/h, 12,000 BTU/h, or 3.5 kW of cooling, and a common rule of thumb for standard commodity plastics is about 1 HP per 80–100 tons of clamp force, rounded up for engineering resins, fast cycles, and hot climates. Undersizing is the single most common and expensive mistake buyers make.

A practical guide to double shaft shredders (twin-shaft shredders): how they work, what they shred, how they differ from single-shaft granulators, blade and capacity selection, and why CE-certified LESINTOR double shaft shredders suit plastic, metal, wood and bulky waste recycling.

Should your plastic factory use standalone vacuum hopper loaders, or invest in a central feeding system? The answer depends on the number of machines, materials, workshop layout, and automation plan. This article compares machine-mounted vacuum autoloaders with central material conveying systems, explains which factories benefit from each, and shows how LESINTOR helps overseas buyers and distributors start with standalone loaders and upgrade to automated central feeding later — all backed by CE certification, one-year warranty, and a full range of plastic auxiliary equipment.
