I. Production Processes Extrusion Molding: A continuous process in which various semi‑finished products of different shapes are produced through the action between the extruder barrel and the screw. Functions: The extrusion process subjects the rubber compound to shearing, mixing, and compression. Characteristics: Wide range of applications and high flexibility; extruded semi‑finished products exhibit uniform, dense textures and can easily be adapted to different specifications. Extrusion equipment is compact, lightweight, features a simple structure, delivers high production efficiency, has low capital costs, and offers substantial production capacity. Calendering: Refers to the process whereby a compounded rubber mixture passes between the two rolls of a calender, with the pressure between the rolls inducing elongation and deformation, thereby producing rubber sheets or tapes as semi‑finished products.

I. Production Process Methodology

Extrusion molding: A manufacturing process in which a variety of semi-finished products of different shapes are continuously produced through the interaction between the barrel wall and the screw of an extruder.

Function: The extrusion process subjects the rubber compound to shearing, mixing, and compression.

Features: wide range of applications, high flexibility and maneuverability; the extruded semi‑finished product exhibits uniform, dense texture and can be easily adapted to different specifications; the extruder occupies a small footprint, is lightweight, has a simple structure, delivers high production efficiency, boasts low capital costs, and offers substantial production capacity.

Calendering: A manufacturing process in which compounded rubber stock is passed between the two rolls of a calender, where the pressure between the rolls induces elongational deformation, producing semi‑finished rubber sheets or tapes. Characteristics: This process places high demands on the technical expertise of operators; skilled operation requires strict and meticulous control of processing parameters. The thickness and surface quality of the calendered sheet must remain within tight tolerances relative to specified targets, and scorching should not occur during high‑speed calendering.

II. Production Equipment

Extrusion molding

Mixing: rubber cutting machine, internal mixer, open mill

Refining and Molding: Rubber extruder, open mill, extrusion molding

The apparatus (comprising a main unit and an auxiliary unit);

Stone Transformation: Stone Transformation Jar

Calendering: calender, single-drum devolatilizer, devolatilization tank, internal mixer, rubber filter, rubber cutter, open mill.

III. Production Process: Rubber Compound Preparation

Various raw materials are subjected to batching, internal mixing, and sheeting;

Filtering and hot mixing to produce a rubber compound;

Roll forming

The rubber compound is extruded or calendered into a sheet.

Stone packaging inspection;

The roll material is further processed through stone‑rolling, inspection, slitting, and packaging to produce finished rolled products.
