Plastic Machinery & Parts

Plastic injection molding for automotive applications sits at the intersection of material science, tooling precision, and repeatable manufacturing discipline. This offering — built around Model Solutions Injection Molding — addresses the full spectrum of automotive plastic part categories: exterior body components like front bumpers and bracket assemblies, interior trim and functional pieces, and structural parts that must perform under mechanical or thermal load cycle after cycle. The scope is not limited to high-volume runs; the production setup is equally suited to low-to-mid volume programs where dimensional accuracy and surface quality carry as much weight as throughput.

Device overview: Electrical Supply: 380V/3P/50Hz Control voltage: 220V,50Hz, 24V Material extruded: HDPE Virgin material or HDPE recycled material Useful Width: 1100≈1150mm Thickness Range: 1.0≈3.0mm Use of plate: visor peak for caps Layer Number: single-layer φ120 Product properties: micro-foamed board or solid board Extruding output: 150≈180KG/H Installed capacity: about 130 KW Total water consumption: about 100 KG/H Device features: 1、The gear reducer of this unit adopts the latest hard tooth surface gear reducer with high strength, high stability, low noise and large bearing capacity. 2、The screw of this machine is high efficiency, double mixing and double metal separation type, which has excellent plasticizing and mixing ability, especially suitable for recycled granule. 3、The barrel cooling system can automatically adjust temperature using oil, water, or gas (users may select the appropriate cooling medium based on specific conditions). This ensures the material undergoes mixing, plasticizing, and foaming at a constant temperature, resulting in uniformly dense foam sheets with sufficient hardness, toughness, and a smooth, flat surface. 4、The three-roll horizontal installation with synchronous drive and frequency conversion speed regulation ensures smooth operation of the calender rolls. The rolls are made of 45# seamless steel pipes treated with special processes to significantly reduce surface gradients, resulting in smooth, flat sheets with clear patterns. The movable frame allows production of sheets with different surfaces without changing the roll position, thereby shortening roll replacement time and improving efficiency. 5、With minor modifications, the production unit can manufacture PP, PE (microfoamed), PS, and ABS sheets for various industries including luggage, handbags, golf equipment manufacturing, packaging, stationery, and medical boards, significantly enhancing its compatibility.

The core function of door and window sealing strips is to fill the gaps between the door and window frame and sash, and between the glass and the profile. They also need to be adaptable to conditions such as frequent opening and closing of doors and windows, changes in outdoor temperature and humidity, and exposure to sun and rain. Tolerance to extreme temperature fluctuations: Resistant to -40℃~60℃ in frigid northern regions and -20℃~80℃ in hot southern regions. No brittleness at low temperatures (embrittlement temperature ≤ -50℃) and no softening or deformation at high temperatures (heat distortion temperature ≥ 70℃). Elastic recovery rate ≥ 80% after long-term use (over 10 years). Excellent anti-aging performance: Resistant to ultraviolet (UV) radiation, ozone (vehicle exhaust/atmospheric ozone), and rainwater erosion. After 5000 hours of outdoor exposure, standard EPDM strips retain ≥70% of their tensile strength, with no significant cracking or discoloration (as required by national standard GB/T 12002-2016). Glass sealing strip: Embedded in the glass groove to prevent glass movement and rainwater seepage.

The core function of tunnel sealing strips is to solve the waterproofing and seepage prevention problems of tunnel structures (such as shield tunnel segments and lining joints). They must also adapt to complex tunnel conditions (such as structural settlement, vibration, and corrosive environments). Their performance characteristics revolve around "sealing reliability, environmental adaptability, and structural compatibility." High seepage resistance and waterproofing: They must withstand the pressure of groundwater in the tunnel (typically 0.3- 1.0 MPa, reaching over 1.5 MPa in special geological conditions). After the strip adheres to the segment/lining joints, it forms a "continuous sealing barrier," preventing groundwater and sediment from seeping into the tunnel interior. Most use either "water-swellable" or "elastic compression" designs: water- swellable strips can absorb water and expand (expansion ratio 150%-300%) to fill tiny gaps, while elastic strips achieve long-term sealing through structural compression. In some scenarios, both types are used in combination. In tunnel environments that are chronically humid and lack sunlight (or have weak lighting), the strips must be resistant to... "Damp heat aging" and "ozone aging" (vehicle exhaust contains ozone) are required, with a standard service life of ≥20 years (matching the tunnel structure's design life). After aging, tensile strength retention should be ≥70%, and elastic recovery rate ≥80%. UV resistance does not need to be excessively high (UV radiation is weak inside tunnels), but it must withstand temperature fluctuations (-30℃~60℃, down to -40℃ in frigid northern regions), without becoming brittle at low temperatures or softening and deforming at high temperatures.

The sealing gasket in plate heat exchangers primarily serves to seal between hot and cold media. 1. Possesses excellent elasticity and compression recovery, tightly conforming to the sealing groove of the plate after compression to block medium leakage and accommodate pressure demands under various operating conditions. 2. Withstands temperatures ranging from -50°C to 200°C or broader depending on material composition, adapting to thermal fluctuations during hot/cold medium exchange without brittleness or softening. 3. Resists swelling and aging from common heat transfer media like water, oil, and acid/alkali solutions. Does not react chemically with media, maintaining stable performance. 4. Resists tearing, abrasion, and compression set. Maintains original shape and sealing performance after prolonged exposure to plate compression and media erosion, extending service life. 5. Manufactured with high precision and low thermal expansion coefficient. Minimizes deformation post-installation, ensuring accurate fit with plate sealing grooves and simplifying installation.
