Taifu Machinery has focused on the research, development and continuous improvement of vertical injection molding machines since it was founded in 2009. Its machines form thermoplastic and thermoset materials into plastic parts of all shapes, and are known for rigid construction, strong clamping force, fast and stable operation, low energy consumption and low noise. The factory is located in the Yangwu industrial area of Shipai Town, Dongguan, and is equipped with CNC machining centers and gantry milling machines. Taifu integrates R&D, manufacturing, sales and after-sales service, offering standardized, serialized products. Machines are delivered within the lead time agreed with the customer, and the after-sales team provides 24-hour online support.

Over many years of technology transfer and in-house development, Chinese vertical injection molding machines have grown from a single product type into a broad range, and they now play a leading role in insert, overmolding and connector molding. At Taifu, the loyalty and motivation of our people are what make the team effective. We welcome people from different backgrounds, support each employee's professional growth and recognize both individual performance and team results. We value team spirit while respecting different opinions. Innovation is part of everyday work: we welcome new ideas and new challenges. Meeting customers' changing needs is our core task. We communicate openly and honestly, building mutual trust and respect for long-term business relationships.

Customers often ask whether they need a liquid silicone (LSR) injection machine or solid silicone equipment. Here is how to tell the two apart. Appearance LSR parts are highly transparent and odorless, with a visible injection gate and no obvious parting-line flash. Solid silicone parts are less transparent, may smell of curing agent, have no injection gate, and show a parting line where the upper and lower molds meet. Applications LSR: baby products, kitchenware and medical products — items that come into direct contact with food and the body. Solid silicone: daily-use goods, industrial parts, waterproof seals for electronics and automotive components. Material safety LSR is a highly transparent, high-safety material; no curing agent or other additives are added during molding. Solid silicone requires a curing agent to speed up vulcanization, demolding and feeding. Molding process LSR is vulcanized in an injection molding machine. The process is simple, accurate and productive, and saves labor, power and material. Solid silicone is mixed, cut to size and placed into the mold, then formed in a compression press at a set temperature, with mold cleaning required after demolding. Tooling Solid silicone molds are relatively simple and inexpensive — a cavity machined to the part's dimensions. LSR molds are more complex: gate location, cold runner system, venting and mold temperature monitoring must all be designed in, so tooling costs more.

Screw size determines how much material a rotary vertical machine can inject per shot, so choosing the right screw directly affects part quality. Screw too large for a light part: excessive melt volume and residence time tend to burn or yellow the part. Screw too small for a heavy part: the part is likely to be short-shot and fail to meet design requirements. Mold design causes of incomplete filling Over-complex molds with many turns, poorly placed gates, narrow runners, too few gates or the wrong gate type. Very thin local sections: increase wall thickness overall or locally, or add an auxiliary runner or gate near the unfilled area. Inadequate venting: short shots often occur at corners, deep recesses, thin sections surrounded by thick walls, and the bottoms of thin housings molded with side gates. Add effective vents, position gates so air is pushed out first, and where necessary make the trapped-air area a separate insert so air can escape through the gap. Unbalanced filling in multi-cavity molds: reduce the number of cavities if needed to keep the remaining parts within specification.

Every Monday, Taifu holds a safety meeting reminding all staff to protect themselves and others: wear safety shoes, goggles and gloves, and use helmets and safety harnesses when working at height. Fires occur in plastics-related industries every year, so fire prevention is a priority for us. Our approach rests on three points: Training: all employees are trained in using fire extinguishers, evacuation routes, fire prevention in the workshop and proper workwear. Infrastructure: site facilities must fully meet fire codes — clear fire lanes, maintained hydrants and so on. Drills and maintenance: regular fire drills, plus routine maintenance of machines and wiring to prevent short circuits. Following the national fire regulations in daily work, raising safety awareness and inspecting site facilities routinely are the simplest and most effective ways to keep everyone safe.

Challenge With demand for phone and computer data cables growing rapidly, a data-cable manufacturer in Jiangxi needed high-volume, stable overmolding capacity for cable connectors and plugs. Machine Taifu fixed-table vertical injection molding machines, 25–35 tons clamping force. Solution More than 20 fixed-table vertical machines were supplied in 2019. The lower mold is fixed and the upper mold moves, suiting insert molding. Machines feature multi-zone barrel temperature control, proportional hydraulic control, a Taiwanese bimetallic barrel with high-torque hydraulic motor, direct-pressure clamping with high-speed, low-pressure mold close, a liftable injection unit for easy mold and material changes, safety light curtains with automatic fault display and stop, and low-pressure mold protection. Result Stable production with a reported finished-part yield of up to 99.8%.
